The GT604 Complete NFT System includes everything you need to grow plants hydroponically (except media!). The GT systems are compact and effective and many growers choose them for the amazing results they deliver. After you transplant the young plants into bigger rockwool cubes, let them root out a bit more before placing them on the system. When the roots begin to come through the base of the cube, they are ready to use on the GT604! Use a spare cube to cut out holes in the top plate and place the cubes into the holes on to the top tray.
When the pump is active, water pumps up onto the top tray, flows down past the cubes and drops back into the tank at the other end. The pump remains on all the time, constantly bathing the roots in water and nutrients. The water movement helps keep oxygen levels up and the roots have far more access to it. As the top tray sits above the water tank, it keeps it in the dark. This helps prevent algae from developing which can clog pumps and pipes.
The GT604 is very easy to use and when you need to change the nutrients, you can use the pump to do it. Simply disconnect the feed pipe and attach a hose leading to a bucket or drain. This makes draining and refilling easy, like when changing nutrients. These systems are low profile, meaning you don’t lose any head height. They stand just 20cm tall! If ever there was a good introduction to hydroponics.. this is it!
