Plants sit on the Gro-Tank’s sloping tray and nutrient solution is constantly pumped from the tank over the bare roots on the tray above. Whatever the roots don’t take up flows down the slope and back into the tank.
There’s no going back from a Gro-Tank – the results are incredible.
The solution is continuously oxygenated with an air tube. The roots have unrestricted access to nutrients and oxygen – maximising nutrient uptake and growth.
NFT doesn’t require media. Well-rooted plants are added to the Gro-Tank without the need for media.
