^^^^^^^that there is the inst manual for the waterfarms unit and it dont re circulate nuets it uses a gravity system. when the level of nuets in the bottom resv bucket gets low the valve allows a thined out mix of food to be fed into the system and then it uses the same princible as an aquairum to "bubble" nuets to the top feeder ring. to me this is different that the drip feeding that others use and is more common. im not sure but with this system not only do u have to have a PH meter but you have it use it in the resv, the bucket and in the feed lines (more work?). in my setup i just change the food every 5 days. i already know that the water in LA is hard but not hard enough to make the nuet toxic as long as im not lazy about changing it. and this place might not be heaven but the water is well tested and consistant in what it has in it.
Ziggy Stardust Reviewed by Ziggy Stardust on . How does Aquafarm/Waterfarm Recirculate Solution? I was looking at the Waterfarm (buckets attached to a controller-bucket), and wanting to build a system like it, but I want my system to be re-circulating. Where the nutrient solution in the bottom of the buckets is constantly flowing into the buckets, like NFT/SWC, and back out. Iā??ve read threads on the construction of Krusty buckets and DWC buckets, but no-one explains the path the nutes take through the lines and buckets. Some (like Waterfarms) only have a single Rating: 5
