What's the best 1000 HPS for flowering (best red spectrum)?
mr2shim Well-Known Member Aug 11, 2011 #3 are you asking which bulb would be the best? I don't get your question. HPS is best for flowering. Generally they are all about the same and put off roughly the same light spectrum. You can get a hortilux bulb but they are a lot more expensive.
