My question is lights, My grow area is small (4.75sq. ft.) I'm using four 24'' fluorescent bulbs from walmart, 20w each. I have two of the daylight bulbs (1025 lumen each) Do I want the plant/aquarium (750 lumen each) or the kitchen/bathroom (1275 lumen each)?
Question on PH level, do not have a ph meter, any cheap ways to test the water? How important is the ph level? I never worried about it when I grew with dirt, and I use distilled water with the Hydro, as I did with dirt.
