Greetings all. I am an absolute noob -- no kidding. I figure on building 2 stealthy and secure grow cabinets about 2-1/2 foot by 5-1/2 feet inside dimensions -- keeping in mind CA new 2010 referendum for size limitations. One for seedlings / clones / veg state using 2x4 fluorescent tubes, and the other for veg state and flowering using MH. All will be grown organic, in soil. The question is "What kind of MH?" HPS lighting is currently out of the question.
I bought 3 x 250 watt pulse magnetic ballasts, which I can use with either regular MH or with Hg2Vapor bulbs -- I have both types. What I like is that these bulbs are readily available in local HomeDepot / Lowes stores. But I was reading somewhere that the cannabis trichromes grow as a defensive response to protect the plant from UV light. Kind of makes sense, since some of the best sativa cultivars are mountain grown (closer to the UV). I managed to happen upon a number of seeds from a dozen different cultivars, so the experimentation should be fun.
So, do I use the Hg2Vapor bulbs or the MH bulbs for flowering?
