Hi, I just recently got my medical card and am going to be a caregiver for some of the local elderly people at my nanas retirement home to try and save them some money. I am going to start two 24 site dwc undercurrent systems as they seem the easiest. I have 500 sq feet of grow space and am using dutch passions auto flowering think different seeds. My questions are... 1) is 500 sq feet enough for a grow this size? 2) what would be adequate lighting for a room this size (preferrably cfls or other low heat/ energy)? 3) where can I find a complete comprehensive diagram of how to build my own dwc system? 4) what method should I use for auto flowering seeds that will be grown using dwc? germination or just plant the seeds? Thank you in advance.
