Transplanted everyone into 3 gallon pots. Will veg for a while until I get my water situation under control. I am having to run two ro filters to get my ppm under 50ppm. Right now I have them connection together with a pump to get the right psi. I might change it to fill one 42gal with one cycle and pump that through with a different pump that I have. I have two 42gal brute trash cans connected and it’s not filled up much in a couple days. I will see how long it takes to fill bother. How much water do you think I will need for 25 plants in follower in 3 gallon pots weekly ?
