I am getting tired of buying rockwool and will be making an 8 site aeroponic cloner out of a 5 gallon bucket pretty soon. I saw a few setup's through google that I liked but they led me to a couple questions. 1) Does the reservoir on a cloner have to be light proof? Considering I won't be adding any nutrients to the water, there shouldn't be anything in it to cause bacterial or fungal growth. I saw a video of a clear reservoir grow and the roots didn't seem to have been effected by the light at all. They actually looked healthier than my current plans in 3rd week of veg. 2) I was thinking of going with a design that used a plugged garden hose with holes punched in it as a spiraling sprayer. I wouldn't mind spending a little money on PVC and legit aeroponic sprayers but I hear horror stories about clogging. If I am, once again, using water with no nutes (just PH down and superthrive) would clogging even be an issue?
