Just curious what the others are, do you grow your multifloral paphs in the 90s throughout the year?Only cool for the winter, 50-55°F (10-13°C) nights. The rest of the year, it'll be downstairs with the hot growers where it can get up into the high 90's. If that doesn't set its clock to bloom, next winter it'll spend its nights in the refigerator.
I've been wondering what kind of MH fixtures you use, are you using a traditional bulb or a double ended bulb?Winter temps downstairs are 80-85Fday, 63-65F night. My growspace is insulated with 1in thick foam, the house heating pipes run through it, and it's lit by 400W halides that generate a good bit of heat.
I see, I'd love to grow with MH lights, especially having access to 1000W ballasts and double ended MH bulbs, but would worry about all the heat being generated and would definitely need a house for that...so it'll be quite a while from now! lolTraditional, unshielded, Iwasaki 6500°k (they call it hortilux blue nowadays)
