So how exactly does it work?

The gear contains long shallow trays which feature a long lid keeping the device enclosed. There are cut outs in the lid which is where the plants are placed. The plant sits in a plastic pot with slits allowing the roots to cultivate through them. They seem like an inferior version of the inner pot used in flood and drain systems.

The trays are placed above a water tank and a push connected at one end to pump water into the trays. There must be a good gradient in the trays so your water flows down the tray and back in the water tank. Usually the gradients used are 1:30 or 1:40 this stops water pooling in the depressions caused by uneven surfaces and roots. The idea 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 reference to the thin film of roots that will eventually form on underneath of the tray. It takes to be always a very shallow stream of water with only the foot of the roots submerged; this permits the rest of the root to be ready to accept the air and get the required oxygen necessary for growth.

The systems come in different lengths which can take different variety of plants. Essentially you can have any amount of NFT system, nevertheless the longer the device the more chance that flow might be interrupted. Systems longer than 12 metres tend to get less growth in plants towards the finish due to the nutrients in the water being adopted by the plants closer to the reservoir. However this issue could be overcome by establishing 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’re also on all of times meaning that they get plenty of action within the span of the grow. This along with possible salt precipitation from the dissolved nutrients (especially in hard water areas) means that at some point the pump is likely to break down. If you can catch this quickly then apart from the price of a fresh pump, there’s no real problem to the plants. However if this goes unnoticed it indicates that the roots will dry up rapidly and this can affect growth.

Disease 世博娛樂

The plant roots are constantly submerged in water and this could lead to bacterial infections such as pythuim. Pythuim is much better known as root rot and can decimate your crops when it is not detected early. There are products in the marketplace that could eradicate this if you should be unlucky enough to get it, but the simplest way is prevention. This is often achieved by changing the water reservoir periodically and adding preventative additives to the nutrient solution.

Stability

Heavy fruit yielding plants can become unstable in an NFT system. This is due to the roots growing long and flat and devoid of any a great deal of purchase. This causes the plant to become top heavy and they fall from the trays – not ideal! This is often overcome by supporting the plants by utilizing yo-yos, string or canes. This will give some stability to the plant and allow it to continue growing and bearing fruit without toppling over.
