Bill, I think your question can be better answered if we have more information on your greenhouse. I'm assuming it's located outside. What are the dimensions of the whole greenhouse. Is it heated? Is energy consumption an issue? Are you locked in to CFL's or are you looking for the most bang for your buck. Is this something your doing as an experiment or are you planning to do this on a yearly basis. Alot of questions I know but the more info we have the better answer we can give. And dcarch is probably one of the most knowlegeable people at TVille on the subject. Ami
