- 1. According to my uvb meter these lamps produce 300 -400 uw/cm2 at 12-18 inches from the plants.
2. I supplement uvb from sprout to chop on the same timer as the main lighting
3. see above...the sun emits uvb always
4. start out at 300 for indicas and 400 for sativas...maintained til the end
5. these are the T5HO 2 bulb fixtures I use...great pricing, holding up well and externally ballasted..I use four of these 1 fixture in each corner in 5x5x9 height rooms.... http://www.aquatraders.com/48-inch-2...re-p/52123.htm
