Hey Rump,
I know you grow in a 4'x'2' space. I am dealing with a similar, but smaller space ( 42'' wide x 16'' and plenty tall at 90''). I am inspired by your setup and would like to mimic/duplicate it for the most part. My question: I know you grow with 2 plants and 1 reservoir. What do you think about 1 plant and 1 reservoir for my space? Do you think the PH would swing too wildly?
Beautiful design BTW. Your posts are a great boon to the community here.
