Hydroponic Sytems Piece a pair of – Chemical Roll film System NFT

How does it work?

The equipment includes long shallow trays which feature a long lid keeping the system enclosed. There are cut outs in the lid which can be where in fact the plants are placed. The plant sits in a plastic pot with slits to allow the roots to grow through them. They seem like an inferior version of the inner pot found in flood and drain systems.

The trays are placed above a water tank and a push connected at one end to pump water to the trays. There should be a good gradient in the trays so that the water flows down the tray and back into the water tank. Usually the gradients used are 1:30 or 1:40 this stops water pooling in the depressions brought on by uneven surfaces and roots. The concept is that the roots of the plants are continuously bathed in a nutrient rich water supply and produce healthy, linear growing plants.

The name nutrient film is in mention of the the thin film of roots which will eventually form on the bottom of the tray. It requires to become a very shallow stream of water with only the foot of the roots submerged; this allows the remaining root to be open to the air and get the mandatory oxygen necessary for growth.

The systems can be found in different lengths which can hold different variety of plants. Essentially you could have any length of NFT system, however the longer the system the more chance that flow could be interrupted. Systems more than 12 metres tend to obtain less growth in plants towards the end due to the nutrients in the water being adopted by the plants nearer to the reservoir. However this problem can be overcome by creating another water supply along along the channel.

Pump Breakdown

As NFT systems only require a small, shallow water delivery the pumps used are not very powerful. They are also on all of times meaning that they get plenty of action on the span of the grow.  shibo NFT This coupled with possible salt precipitation from the dissolved nutrients (especially in hard water areas) implies that at some point the pump will probably break down. If you can catch this quickly then besides the price of a new pump, there is no real problem to the plants. However if this goes unnoticed this means that the roots will dry out very quickly and this may affect growth.

Disease

The plant roots are constantly submerged in water and this could lead to bacterial infections such as for instance pythuim. Pythuim is much better known as root rot and can decimate your crops if it is not detected early. There are products available on the market that could eradicate this if you are unlucky enough to obtain it, but the easiest way is prevention. This can be accomplished by changing the water reservoir periodically and adding preventative additives to the nutrient solution.

Stability

Heavy fruit yielding plants can become unstable within an NFT system. That is due to the roots growing long and flat and not having any a lot of purchase. This causes the plant to become top heavy and they fall out of the trays – not ideal! This can be overcome by supporting the plants by using yo-yos, string or canes. This will give some stability to the plant and give it time to continue growing and bearing fruit without toppling over.
