I'm thinking of using 1000 watts of fluorescent over HPS/MH. Anyone doing this? Does it need ventilation of heat?
Are you thinking of using a 1000w of CFL's? You might want to consider HO T-5 flourescents some very good jounals using them here on G.C. Here's an excellent CFL guide http://forum.grasscity.com/general-indoor-growing/122824-kamels-cfl-guide.html and here's a T-5 HO jounal http://forum.grasscity.com/indoor-grow-journals/477361-t-5-autoflower-grow.html and another T-5 http://forum.grasscity.com/general-...cs-results-t5-veg-flowering-bagseed-soil.html I would use tubes for that much wattage I can't remember seeing a 1000w CFL grow yet.
