Gro-Tank is the classic NFT system - a shallow film of nutrient running continuously past bare roots. There is no medium to buy or dispose of, roots get constant oxygen and feed, and growth rates in a working NFT system are as fast as anything in hydroponics. The kits are sized by plant count, so you pick by how many you intend to run.
- Complete kits: GT205 (1-3 plants), GT090 and GT424 (2-5 plants), GT604 (3-7 plants), GT100 and GT901 (4-9 plants) - see all NFT systems.
- Multi Duct: The Gro-Tank Multi Duct NFT complete kit for running separate channels.
- Spreader matting: NFT spreader matting, which distributes the nutrient film evenly across the channel instead of letting it run down one side. Browse grow media.
- Trays: The Libra tray for slabs at 100 x 16 x 9cm - see trays and saucers.
Why choose Gro-Tank?
No medium at all. Nothing to buy, nothing to sterilise, nothing to throw away, and no medium chemistry to manage - just the solution. Provided the pump keeps running, NFT gives you the fastest vegetative growth available and the simplest root zone to diagnose.
Gro-Tank FAQs
What happens if the pump fails?
Bare roots dry out quickly, so NFT is less forgiving of pump failure than a medium-based system. A backup pump is a sensible purchase.
Do I need spreader matting?
Strongly recommended. Without it the film channels down one side and half your roots sit dry.
