For my indoor grow, I have 1 Trinidad Moruga scorpion in a 5 gallon bucket, and depending on germination, will later have one or 2 Chocolate Bhuts in 5 gallon buckets next to it. I'm going to need a fan to help with pollination. What kind (model, Size RPMs - price range - ) do I need and how many hours a day (all the light hours?) should it be on.
