What’s NFT?

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! 

We recommend

Don’t forget to buy transplanting cubes, cutting seed cubes, your nutrients (we recommend using Shogun Samurai) & a pH test kit

It’s worth buying a spare Correx cover & spare pump too.

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.

The results?

• Monstrous roots
• Extreme yields
• Shorter growing cycles!

Save Height

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.

Do you run the nft 24/7 or do you have the pump on a timer so the roots dont get saturated
You 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.

nft 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 tank
You could use either the Gro-Tank 1000, or 2 x NFT Gro-tank 424 in a 1.2 x 1.2m tent.
