Plants sit on the GT’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.

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 GT without the need for media.

There’s no going back from a GT – the results are incredible.
