Get epic roots & giant yields in a shorter growing cycle! All you need is an NFT Gro-Tank!
Your yields will be up to 3 x bigger than if you grew in a pot!
It’s cheap & easy to manage each system - they run 24/7 & minimal growing media is needed.
You’ll save tons of headroom, too – NFT Gro-Tanks are just 20cm high! If you haven’t got the height for bubblers, an NFT Gro-Tank’s great!
They’ve been a bestseller since 1994 and are still going strong – that’s how good they are. Find out what all the fuss is about - try one today!
• Easy to manage - systems run 24/7 without a timer or controls!
• Yields up to 3x bigger than plants grown in pots!
• Unrestricted growth – roots have a constant oxygen & nutrient supply
• Compact – space saving – ideal for low heights!
• Giant roots in record time!
• Low waste! Recirculates nutrient solution – minimal growing media to throw away
• Efficient! Shorter growing cycle!
NFT is for Nutrient Film Technique!
A shallow stream of nutrient solution is constantly pumped past bare plant roots.
Roots get almost unrestricted access to oxygen, water & nutrients. You know what that means? Yes! Epic roots, huge yields & a shorter growing cycle!
NFT systems are easy to manage - systems run 24/7 without a timer or controls.
It’s no wonder that commercial growers worldwide use NFT!

- The Science
How it Works
Plants are placed in rockwool blocks and onto your Gro-Tank’s top tray.
A nutrient solution is pumped to your roots in a shallow, steady stream. Your plant roots then grow along the planting channels in the top tray.
This gives your plants a constant, unrestricted supply of oxygen and nutrients.
• Monstrous roots
• Extreme yields
• Shorter growing cycles!
NFT Gro-Tanks are compact (only 20cm high) and self-contained!
If you haven't got enough height for a bubbler, an NFT Gro-Tank's a great alternative!
• Completely self-contained
• Ideal when there's resricted headroom
• Great alternative to a bubbler
Effcient & Low Waste!
NFT Gro-Tanks are incredibly efficient! Very little growing media is used - only the rockwool blocks you establish your plants in.
Since your nutrient solution is recirculated, little water's wasted, too. It gets pumped from your reservoir straight to plant roots then back round again.
You don’t have to worry about watering your plants – systems run 24/7. You only need just need to check your system, top up your tank and empty your tank roughly once a week!
• Systems run 24/7 without a timer - efficient!
• No watering – reservoir only needs emptying around once a week
• Hardly any growing media - only the rockwool blocks!</p

- How to Use
See how to assemble your system by watching the video above.
Positioning your rockwool cubes
When you position them, make sure that the grooves in your rockwool cubes are lined up with the flow of water, to ensure nutrients can reach your roots.
Topping up your tank
The easy way:
Top up your tank with a quarter strength feed as required, with a complete nutrient change once a week.
To precise way:
Top up your tank as needed with quarter strength feed. Once you’ve topped your tank up by its full capacity (e.g. by 6 litres in a 6 litre tank) you'll need to completely empty and refill your tank.
Never turn your pump off – roots are meant to be kept moist. If you do turn your pump off, your roots will quickly dry and you’ll get lots of cell damage (even dead root mass!) When you finally turn your pump back on, Pythium can quickly take hold.
- Q & A
Questions and Answers (10)How easy is it to change the water/nutrient solution ? Does this become more difficult as the plants mature ?These systems feature a nutrient inspection area at the end of the tanks. The easiest way to change the nutrients is to use another pump, & a length of tubing to drain the tank.
Written by AW | 2 Dec 2013Do you run the nft 24/7 or do you have the pump on a timer so the roots dont get saturatedYou would run the pump 24/7 in an NFT system. As the roots are exposed in this system, they need a constant source of moisture.
Written by Bob | 30 Nov 2013nft gro tank, want to use a tent as part of my set-up but want to use say a 120*120 tent so need to know what size tankYou could use either the Gro-Tank 1000, or 2 x NFT Gro-tank 424 in a 1.2 x 1.2m tent.
Written by leon | 13 Sep 2013Can I use this all the way up until harvest? Will the roots clog anything up?The NFT Gro-tanks are designed to allow you to grow plants to maturity, the roots should not clog up the pump.
Written by Harry | 16 Jun 2013How many normal sized plants can you fit in the nft grow tank 1000You could fit 9 large plants, or up to 25 smaller plants into the GT1000 system.
Written by Billy | 15 Apr 2013Hi what's the lowest height you could hang a 600w light from with a shield that would not harm the plants as I have restricted height For the NFT 205 GTII would say that the lowest that you could have your light would be 70cm from the top of the canopy, when the plants are mature. For earlier stages of growth, I would recommend having the light around 140cm away.
Written by Lewis | 26 Aug 2012do u have the pump on 24/7 or 4-6 25mins intervals,how many plants can a gt205 takeYou need to run the pump 24/7 in an NFT system, you can fit 2-4 plants in the NFT 205 GTi .
Written by EJ | 5 Nov 2011can you use clay pebbles with this system?We would recommend just using the rockwool blocks for this system, as clay pebbles would restrict the run of the nutrient.
Written by sam | 27 Oct 2011What sort of root mass can be accommodated? Would 6 large plants be fine in the 604, or would there be a danger of blocking/clogging sprays? Also, is it whisper quiet, or is the noise that of a standard pump? Thanks!The NFT 604 Gro tank will comfortably accomodate 6 large plants, we would recommend using a product such as Cannazym to maintain a healthy root system. The pump in the tank is very quiet, we would recommend using a slightly longer length of spreader mat going into the reservoir from the top tray to minimise noise.
Written by DS | 7 Jun 2011is there a correx cover supplied with the nft gro-tank 404?,,,thanks:)The 424 Gro-tank comes with the tank, top tray, pump, delivery tube, & correx. These are all available as spares also.
