Hello all. I recently bought a full grow package from someone. It was 5 4x4, 5 1000 watt hps with switchable ballast, buckets, air stones and tubing to set it all up, and reverse osmosis setup. I have a few questions. What would get more yield, 2 plants with scrog, or 5 or 6 plants. I watched several videos, and most had a bucket with a drain hose, mine are just buckets, does that mean I am missing a resivor? Also for feeding I have fox farms dirty dozen. Looking at the hydro feed schedule, dies that mean each 5 gallon bucket gets that amount, or per gallon. If the bucket didn't have a drain, how do I change water without hurting or stressing the plant?
