Gro-Tanks are often referred to as 'pure hydroponics' because virtually no growing medium is used and roots benefit from unrestricted access to oxygen.

Nutrient solution is constantly pumped up from the reservoir to the roots in the planting channel and flows back into the reservoir ready to be passed over the roots again.

Zero waste – the only growing medium used is the rockwool block the plants were started in. This means there's less chance of disease and less waste material to throw away at the end of the season.

3x Bigger Yields - The constant supply of water and nutrients directly to the roots combined with unlimited access to oxygen means plants are healthier, faster growing and produce 3x more yield than if grown using traditional soil methods.

Healthier plants – plants are never under-fed or over-watered and there is no build up of salts in the root zone.

Get more out of a small space - Gro-Tanks are just 20cm tall and there's a system for every tent size!


NFT stands for ‘Nutrient Film Technique', a very shallow stream (or film) of water containing dissolved nutrients is constantly pumped past the bare roots of plants. 

The main advantage of the NFT system over other hydroponic methods is that the plant roots are always exposed to a perfectly balanced supply of water, oxygen, and nutrients. In every other method there is a conflict between these requirements, the optimum amount of one results in an imbalance of one or both of the others.

The secret to NFT's success is that because very little growing medium is used a thick root mat quickly develops, the upper surface of this root mat is always exposed to the air (so the roots have superb access to oxygen) and the roots are always moist with water and nutrients.

This means that plants have access to the optimum amount of water, oxygen and nutrients all at the same time. The result is higher yields of high-quality produce and a longer period of cropping.
