hydroponics gardening guide how to prepare starter cubes

Starter cubes, used by hydroponic growers, as well as soil gardeners, are comfortable growing media for starting seeds. Made of inert material, starter cubes provide perfect support to the plant and its rhizomes. The cubes are capable of retaining water, but they do not supply a plant with any nutrients, unless the latter are dissolved in the water. Nowadays, there are 4 types of starter cubes: Organo-Cubes, Oasis cubes, Rockwool and “peat pots”. The most popular among the gardeners are the first three kinds of cubes (Organo-Cubes, Oasis cubes and Rockwool), while “peat pots” lose their popularity due to their tendency to accumulate too much water, which can spoil the seeds and the seedlings. Oasis cubes, Rockwool, and Organo-Cubes, on the other hand, retain water along with enough air, which prevents the medium to be too moist.

Preparing hydroponics starter cubes for the use depends on the type of the cube you have. For example, Organo-Cubes are ready for use, while Oasis cubes and Peat pots should be soaked in water (with pH adjusted to 6 – 6.5) before use. As soon as the cubes are saturated with water, they should be left to drain a bit, and then they are ready to be used. Rockwool is different, since it has high pH. Therefore, it should be soaked in water with pH adjusted to 5.0 in order for this acid solution to be balanced to the pH level required for the plants normal growing. These cubes should be soaked in water approximately for 24 hours, followed by the drainage prior to the use.

Having done these easy manipulations, the seeds can now be planted. Small holes about ¼ to ½ inch deep should be made in the cube with a tip of a pencil or a pen. Then seeds may be put into the holes and covered with some cube material from around those small openings.

It is best to keep the seed cubes moist, but not wet, always preventing them from staying in the water. The cubes do not need light until the seeds germinate. Similarly, no nutrients are necessary for the plants until they have their first true leaves developed. In this case a diluted nutrient solution

Tips On Home Made NFT Hydroponics Systems

Nft hydroponics systems have been round since the mid 60’s Allen cooper of England developed nutrient film technique.

The fact that nutrient film technique hydroponics has many advantages other soil culture, but the biggest is the fact that the root system of the plants have constant access to oxygen and that plants have access to as much or as little water as they need, this is important as one of the most common errors when growing is over/and under watering, and that hydroponics prevents this from occurring as large amounts of water can be made available to the plants roots and water that’s not used simply drains away, recalculating and then actively aerated, which eliminates anoxic conditions which can cause problems in root systems.

In siol, a grower needs to be very experienced to know exactly how much to feed there plants, too much and the plants will not be able to access oxygen, too little and the plants will lose the ability to transport nutrients, which are typically moved into the root while in the solution.

MAKING YOUR OWN NFT HYDROPONICS SYSTEM

One of the biggest mistakes “not the only one though” is using oval guttering for your homemade system, as the very nature of this system is to have a film of water “between 1mm & 3mm” over a fairly wide surface area, so as you can see, using a round water gully is somewhat pointless.

As you can imagine, using a squire gully makes life a lot easer as the fidally job of light proofing your water channel, by other means has already been taken care of, all that’s left for you is to blank of the end and cutting out some holes for your plants to grow in, also a way for the nutrients to recalculate back to your nutrient tank

My NFT hydroponics system that’s used in my greenhouse, I’ve built as a vertical NFT hydroponics system, as space is very limited, although I have managed to use every inch available, with 68 plant spaces available for my crop plants, and that just one half of my greenhouse, with plenty of room for more on the same side to add channels too.

Making your hydroponic NFT system water tight, at the same time as being able to remove the channels from a homemade NFT hydroponic setup is easy enough as long as you give a little thought into how.

As your water needs only to be 1mm to 2mm depth within the water gully channel, so any lip/ edges need to be as flat as the base of the gully, any extra height will increase the depth of the water dramatically, and may cause some water logging at the far end.

· NFT WATER PUMP to large/powerful

Using the right water pump is also very important, as having on that to large/powerful, will mean you having to restrict the flow from your reservoir, which will put a strain on the water pump and at the same time, may over heat your nutrient solution too as the max temperature for the water solution is 21c, any hotter and nutrient lock out will take over and some algae may start growing too.

· NFT WATER PUMP to small/underpowered

Depending on the high or distance your water nutrient solution needs to travel, take my vertical NFT hydroponics system for example, the height of which the water needs to travel is two meters, so a 1000 Litre an hour water pump is just right for the job, although with a horizontal NFT hydroponics growing system, getting hold of a pump that’s to small to manage the small vertical clime is fairly difficult, as I’ve even used a bird bath fountain pump before, but I don’t recommend these pumps as there not all that cheap and also break down more than most pumps too.

· NFT WATER TANK

Choose a Tank that’s no higher than your lowest gully, and of course it need to be light proofed to fervent algae growth and also large enough for lots of nutrient enriched water.

Because NFT hydroponic systems are so susceptible to pump and other failures, I use soaka felt that’s used in bench top growing to soak up excess water and to help with stopping plants from falling over, as plant roots grow into the felt side of the matting, and its ideal for NFT systems as a fail safe, if placed in the bottoms of the NFT channels it will help eliminate any dry spots accruing as the roots grow within the growing channels, as the roots grow, some damming of the water solution may accrue, and at least this felt will help with damming and also pump failure.

· NFT HYDROPONICS HOMEMADE MEDIUM “TOP TIP”

You’ll probably have noticed from looking at other nft hydroponics homemade system setups that square rock wool cubes are mainly used, but as my NFT system is a also homemade, I’ve tried keeping the cost down as 70 rockwool cubes would have cost a few quid. so to avoid this expense, my alternative, Earthwool zero carbon loft insulation, the roll covers 8sq meters, so I’m guessing that’s enough to fill my pots and the best part is that the hole roll cost me 5 quid from my local hardware store.

· REMEMBER

All rock wool fibre has a high PH value, which if not balanced to your hydroponic nutrients solutions PH value before use, will throw you your hydro fertilizer off wake, “above 6.5” so soak in a water solution of 3 Ph, over night in a bucket first, then squeeze out the excess water before installing.

Pots that I’ve made for the NFT gullies, all the PVC pipe is, 40mm waste piping, that cut to length, plus a bit extra so’s I can pull the pot out when needed, oh yeah a small groove that will let water underneath the pots easily, Earthwool zero carbon loft insulation IS VERY loose/ airy, and in my opinion is better than the ready bought cubes, as you can decide how airy you need your medium to be, and also mix with other hydro growing mediums if you wish.

If you do try these pvc pipe hydroponic pots with Earthwool zero carbon loft insulation then you’ll need to roll the earthwool up fairly tightly, so’s the nutrient rich water solution is drown up the rock wool.

Alternatively you could use rock wool slabs, take the plastic wrap off and cut the rock wool slab into slices, doing it this way would also keep costs down.

· GLUING YOUR HYDOPONICS HOMEMADE NFT SYSTEM TOGETHER

Choosing the right glue to keep nft systems water tight, and keeping the pvc pipes water-tight, well you have a couple of options, I’ve tried both of these and each work well, utility/ bathroom/kitchen, silicone sealant is fine to use, or pvc piping and guttering is also very good too, which ever one you do you use, you’ll need to lightly rub the surface where sealing is needed with some sand paper to ensure good contact.

As an avid gardener for many years and also worked in garden nursery's with interests in hydroponics stretching back to the early 90's.

the World’s Smallest Hydroponic System

Lovers of tiny homegrown horticulture, rejoice. This is the LabBox Grower, a hydroponic grow box that's here to assist you in your quest to produce very small herbs. And—of course—it's got Twitter integration.

The LabBox Grower, from the PocketGrow, is a brightly lit adventure in miniaturization. And it's got a few technological treats thrown in as well:

The system is made of a few distinct elements: the LabBox Grower itself, with specially selected high intensity LEDs and a nutrient delivery mechanism; the LabBox brain, a controller that automates watering cycles, light schedules, and temeratires; and finally, an iPhone (surprise), through which the whole thing is controlled.

Getting the roots of the problem

When you have your hydroponics system set up you are continually checking your pH levels, your nutrient solution and grow room conditions it is easy to forget about your roots. The roots of your plants however are like their mouths and understandably ensuring they are healthy and functioning properly is key to ensuring the health of your plants.

Rootbound is a common problem and results when your plants’ roots do not have enough space in which to grow and develop. This in turn stunts the growth of your plants and can have a dramatic effect upon the size of your yields; in the worst circumstances it can even led to the death of plants.


Rootbound will typically occur when your plant pots are too small for your plants, causing the roots to deform and become entwined with each other. This reduces the space from which the roots can draw nutrients and subsequently reduces nutrient absorption and eventually growth. It can however be prevented by having various sizes of pots and transferring your plants as they grow.


If you want to spot if your plants are rootbound you should look for yellowing or browning leaves which are beginning to curl. These symptoms aren’t exclusive to rootbound and may indicate other problems such as insects or even root diseases like Pythium root rot.


The best course of action to prevent rootbound and other problems is to check your plants regularly, looking for roots that are tightly bundled (rootbound) or dark brown (rotting). If your plants are beginning to outgrow their pots it is time to change them, if they are infected however, you will have to clean the system in its entirety with bleach, ensuring that it is thoroughly rinsed afterwards. You may even want to replace some of the harder to clean items and also add a plant immune booster to your nutrient solution.


Checking your roots regularly is the best way to prevent them becoming cramped and diseased. As always with hydroponics prevention is better than cure if you want healthy plants and bumper yields.

Hydroponic Nutrients and Growing Mediums

Hydroponics gardening is a way of growing plants central in the growing average added than soil. One of the methods includes suspending the roots in the baptize band-aid with the attenuated hydroponic nutrients in it. Such address offers the plants an achievability to get all the all-important minerals & vitamins for the optimal growth. As a result, nutrients are acclimated added finer & the crops acquired with such address are added good & richer than those developed with added agronomical techniques.

All of gardeners, who abound plants hydroponically inside, adopt the Ebb & Flow technique, which amnion the plants with the advice of the set timer & pump, triggered by the timer. When the address turns on the pump, it floods the growing tray with plants, consistently bartering them nutrients. This ability makes it achievable to accomplish the all-important altitude for the plants to abound best. It additionally allows application assorted types of media. However, it needs to be consistently acquainted in & needs electricity to operate.

Hydroponics food (e.g. Gravel & Abound rocks at the basal of the abound tray) aid in the accouterment nutrients to the plants roots. Small alone plants containers are beneficial, because they are simple to move if necessary.

The Baptize Culture address suggests growing the plants on a Styrofoam belvedere that floats on the baptize with the attenuated hydroponic nutrients. This baptize band-aid is consistently aerated with the pump, so that plants get the all-important bulk of oxygen. Plants that charge abundant damp to advance (for example, blade lettuce) are the best candidates to be developed application this aloft agronomical technique. Added account of this address is the adventitious to advise accouchement the basics of growing plants, if it is abiding in the classroom.

The wick address is said to be the simplest agriculture technique. It consistently provides plants with a abiding accumulation of nutrient-rich baptize with the advice of a wick, which one accomplishment is sunk in to the solution, while the added one is in the growing medium. This address does not charge adult & big-ticket equipment. On the added hand, it is not acceptable for the ample plants, as they may charge added cogent amounts of baptize in the beneath time aeon than the wicks can supply.

To sum it up, gardeners can nowadays aces from assorted hydroponics gardening systems. Each of them has its advantages & benefits; thus, it is up for a agriculturalist to aces what apparel him best, which one appears to be the best convenient, & which may accommodate the richest crops of the accurate plants a agriculturalist designs to grow. Be absolute that with this array of systems & methods of growing central anybody – a abecedarian & an accomplished agriculturalist – will get pleasure agriculture agronomical all year-round.

Hydroponics Systems and Other Considerations

Hydroponics<n most hydroponic systems grow trays come equipped with top of the line tub outlet drain fitting, allowing users to install a stand-off to adjust the solution level in the tray. The hydroponics system is equipped with a drain to handle high volumes of water.

The hydroponic system includes a channel-like trough formed of extruded plastic, the trough having parallel side walls and an orthogonal bottom wall defining an upwardly opening coffer. A pair of oblique walls extend integrally from a medial portion of the bottom wall to a respective medial portion of the side walls to define a V-shaped bottom in the interior of the trough.

The hydroponic system you set up is going to be on a strict watering schedule that is set by you, and which you must follow rigorously for the good of your plants. This will prevent your plants from getting too little or too much water.

The hydroponic system in my house is set up in a walk-in incubator in which the temperature was kept at 25 degrees C. Eight polycarbonate hydroponic trays (27 cm long by 21 cm wide by 14 cm deep), each designed to hold 12 plants, were used.

The hydroponic system mainly consists of culture containers and mineral wool slabs. The hydroponic system is used within a controlled-environment room (CER) for control of the aerial environment. The growing shed/incubator is equipped with an auto calibrating system for atmospheric CO2 control.

Plants grown in soil-free gardens have the perfect balance of nutrients and water delivered directly to their roots when the best nutrient feed products are used. Crops are not forced to expand their limited energy searching for water and food. Plants in the famous, NASA originated, aeroponic system showed increased vegetative growth, delayed tuber formation and an extended vegetative cycle of about seven months after transplanting.

Plants grown in pots usually hit growth plateaus when they become root-bound, requiring messy and difficult transplanting. A properly designed hydroponic system can avoid this and many other problems commonly found with soil pests are simply non-existent. However, Both hydroponic and soil-grown plants need 16 elements in order to grow. The top three elements, known as macronutrients, include nitrogen, phosphorous, and potassium. Three other elements essential to plant growth, known as secondary nutrients, are calcium, sulfur, and magnesium. The remaining nutrients are called micronutrients. All sixteen of these nutrients are vital to any growing system. In any good hydroponic system, the plant receives all these elements in its water.

Plants thrive even with such a small root volume because just the right amount of water containing a soluble fertilizer is continually dripped into the medium. Plants require light in order to photosynthesize, so if your hydroponic garden is an indoor garden then you may consider using artificial light. A regular light bulb will not be any good in this situation.

Hydroponics LED Grow Lights - Is Our Dissatisfaction Our Own Fault?

We all grew up in Hydroponics using HID grow lights, even though we know the heat and high cost disadvantages. And, to be honest, the technology of LED Grow Lights years ago was not very good or effective for growing Hydroponics plants.

Technology for LED grow lights has improved, and manufacturers have improved the quality and spectrum. So why are so many of us still unhappy with the results, or still afraid to install LEDs as our Hydroponic lighting system?

We have all learned how to maintain Hydroponics plants grown under intense HID lights, what to do about the heat output, plant nutrients, and watering cycles. Why should anything change?

There are two big differences between HID and LED grow lights for Hydroponic lighting; the heat output and the "viewed" light intensity. There is relatively no heat output from an LED grow light, and the light intensity is based on Hydroponics plant requirements, not what our human eye perceives.

Heat from HID grow lights in an indoor grow room affects plant nutrients and watering cycles, just as if your Hydroponics plants were growing outdoors in the hot sun. Take away the heat, and plants do not need as much watering or plant nutrients.

But have you changed your routine after installing LED grow lights? Many customers I have talked to did not, and they lost their plants. When you purchase LED lights, you need to go back to square one using your Hydroponic meters for moisture and plant nutrients strength. You cannot keep the same routine and schedule; you will lose your Hydroponics plants from over-watering or overfeeding.

Over-watering will slow root development or cause root rot, stunt plant growth, and cause plant nutrient uptake issues. Check to see if the soil is drying out before watering again. Use porous grow medium, which will allow more oxygen to reach roots, increase plant metabolism and growth, and will help avoid over-watering problems.

Plant nutrients also must be adjusted in order to not over fertilize, which can also be deadly to Hydroponics plants. Start with a smaller amount of plant nutrients, around half of the amount recommended by the manufacturer. Keep a close eye on the growth pattern and color of your Hydroponics plants and adjust the plant nutrients until the growth rate and color are normal. It is absolutely a pleasant benefit to save money on water and plant nutrient costs also.

Light intensity from an LED grow light is a big difference also. LEDs do not give off a bright light glare like HIDs and electric lights have, which does not mean they are not good for your Hydroponics plants. The spectrum provided for the Hydroponics plants is, again, more like growing your plants outdoors in soil and sun. The plants will grow a little slower, which will take more patience. However, since the spectrum provided by LED lights is more specific to your Hydroponics plants needs, they will absorb the light they require and grow healthier.

Most manufacturing specs show an allowable height of 6' to hang your LED grow lights from your plants. The proper height for maximum benefits when growing tall Hydroponics plants should not exceed around 3'. If you keep your plants pruned and cropped, the light intensity will be strong enough to cover the plant canopy from top to bottom for 5' Hydroponics plants, which is what we all strive for.

If you feel more comfortable with a transition while you convert from HIDs to LEDs, you can experiment with your Hydroponic lighting until you achieve the exact results you are looking for. Use your HID lights for a few hours each day, then use your LED lights for about 10 hours a day. The money you save will still be close to 50%, your HID bulbs will last longer, and your Hydroponics plants will receive the spectrum advantages from LED grow lights. There are also some experiments being conducted, with some initial success, with running the LED grow lights for 24 hours a day, and seeing up to 40% more growth. The Hydroponics plants did not seem to be affected without the day/night cycles.

Give LED grow lights a chance. Get to know their quirks and capabilities, just like we had to do with HID grow lights. Change your Hydroponic lighting to LEDs or a combination of both, change your plant maintenance habits, and save that money every month. With proper installation and plant maintenance, you will become a believer in LED grow lights!

Using a LED grow light properly will produce healthy Hydroponics plants and save you up to 80% in electric costs, in addition to the savings realized from bulb replacement, grow ballasts, large light reflectors, plant nutrients and water. Hydroponics and LED lights are the future for gardening and crops.

how to spot nutrient deficiency in your plants

As hydroponic growers we are often guilty of spending too much time worrying about the pests and diseases which can affect our plants. As a gardener however you should also be paying special attention to your nutrient balance and amounts, as nutrient deficiency in your plants can be massively detrimental to your crops.


Below is information on the symptoms of nutrient deficiency for a range of different nutrients.

Nutrient	What to look out for …
Nitrogen	If your plants are not getting enough nitrogen they will often be a lighter shade of green whilst lower leaves may be yellow and root, flower and fruit growth will be stunted.
Phosphorus	Your plant may take on a blue-ish tint or even a reddish colour. Yellow leaves which eventually turn black may be evident.
Potassium	The leaves will be thin and papery whilst the edges will appear to be dying, plant growth is also affected.
Magnesium	Yellow lower leaves will be evident and the veins of the leaves may also take on a pale, yellow appearance. Wilting may appear on the lower leaves.
Calcium	Calcium deficiency affects the growth of your plant and prevents the developments of younger stems and new leaves.
Zinc	Expect to see light coloured leaf tissue and once again a papery feel may be apparent.
Iron	Green veins should be visible in conjunction with yellow leaves.
Copper	Dark green leave edges that begin to curl upwards, young leaves also start to wilt.
Sulphur	Younger leaves turn pale in colour, older leaves will still be green, expect to see spindly growth.
Manganese	Stunted growth followed by blotchy patches of yellow on the leaves.
Molybdenum	Physically malformed leaves which are pale green
Boron	Scorched young leaves around the tips and margins.

The effects of nutrient deficiency are often caused by multiple deficiencies rather than a lack of just one nutrient so it is important to look out for all of these symptoms. The best defence is preparation and taking the time to ensure your nutrient formula ensures your plants are provided with everything they need to grow and develop healthily.

Selecting a Right Hydroponics Growing System

Selecting the right hydroponics growing systems doesn't accept to be a difficult task. There are 3 aloft factors to accede aback chief which hydroponic growing systems to use.

1. How abundant space do you accept accessible to set up your hydroponics growing system?
2. What types of plants do you plan to grow?
3. How much do you plan to invest into hydroponics gardening? Will you abound a few plants as a hobby, or will you abound many types of plants on a beyond scale?

There are 6 capital types of hydroponic growing systems acclimated in hydroponic gardening today. Below is a short explanation for all.

The Ebb and Flow (or Flood and Drain) System

The Ebb and Flow (or Flood and Drain) System is fabricated up of a abound tray placed on top of a reservoir. The way this growing system works is by calamity the abound tray briefly with a band-aid of hydroponic nutrients alloyed with water. The plants blot the comestible solution, and any surplus band-aid is drained aback into the backlog to be recycled. The ebb and breeze systems is commonly controlled by a timer and pump which can be set to flood the abound tray several times per day.

The Drip System
The Drip system is the best accepted system acclimated in hydroponic gardening. The drip system operates in a agnate way to that of the ebb and flow system. Hydroponic nutrients alloyed with water are pumped from the backlog up to the abound tray, about the comestible band-aid is fed through baby dribble curve and is dripped at the abject of the plants. The pump is controlled by a timer which can be set to several watering times per day. Some of these hydroponic growing systems acquiesce the surplus comestible band-aid to cesspool aback into the backlog for recycling, the aforementioned as the ebb and breeze system. These kind of growing systems are accepted as recovery systems.

The Wick System

The Wick system is a actual simple growing system and requires little accomplishment to maintain. The Wick systems are a acquiescent system, with no affective genitalia to it. Comestible band-aid is fatigued from the backlog up to the advance tray via a wick. Various growing mediums can be acclimated with these hydroponic agronomical systems including Vermiculite, Perlite and Coconut Fiber.

Deep Water Culture System
The Deep Water Culture systems is the best basal hydroponic growing system, and was the aboriginal to be acclimated in the aboriginal days. The Deep Water Culture systems consist of a backlog abounding with comestible solution. A amphibian belvedere is placed on top of the solution, and the plants abound in this belvedere with their roots blind bottomward through the belvedere into the solution. An air pump is commonly acclimated with these kind of hydroponics growing systems to accommodate oxygen to the plant's roots.

Nutrient Film Technique (or NFT)

The Nutrient Film Technique (also accepted as NFT) is an actual accepted hydroponic agronomical system. The NFT systems is hardly altered to added growing systems in that the plants abound in a attenuate Film of comestible and oxygen-rich water. The comestible and water band-aid is pumped into the abound tray or tube which flows beyond the plants roots, and the surplus is drained aback into the backlog for recycling as in the aloft systems. Usually there is no growing average acclimated with this growing systems as the plants are accurate in baby baskets which acquiesce the roots to adhere bottomward into the comestible solution.

Aeroponics
Aeroponics technically isn't a hydroponic system; about it is agnate in the way that it makes use of comestible band-aid and air to abound plants after soil. Aeroponics operates by application air as its growing medium. The comestible and water band-aid is sprayed as a accomplished brume anon assimilate the roots of the plants. The plants are abeyant on a lath or belvedere with their roots blind bottomward into an amid backlog or basis alcove below. The backlog or basis alcove is deeply closed to assure the roots from ablaze and anticipate evaporation. Any comestible band-aid that's not captivated by the plant's roots is calm in the backlog and recycled.
Plants developed in an Aeroponics system accept added oxygen to their roots than those which are developed in added systems. The aftereffect is greater bulb growth. Aeroponics additionally makes added able use of water and activity than agriculture or acceptable bulb growing methods.
The Aero Garden uses Aeroponics and hydroponics systems technology and is an abundant way to acquaintance the allowances of hydroponics. Growing plants in an Aero Garden is absolutely accessible and doesn't crave you to accept a blooming deride or be an agronomical expert. Reviews from users of the Aero Garden appearance that bodies who ahead struggled to abound plants central are now able to get pleasure growing their own beginning herbs, flowers and vegetables
