1. White reflects more light than any kind of silver or aluminum. Do some research, prove it to yourself.
2. Mirrors SUCK for reflecting light, the light loses energy/power both ways going through the glass.
3. CFLs work OK, but you need BIG ones, like 300watt ones that use 65 watts (see pic)
4. LEDS are good, MJ likes blue for veg and red for flower, metal halide bulbs are bluish/for veg and high pressure sodium are orange-ish/for bud.
MH and HPS bulbs are expensive and need to be replaced every 12-16 months, but LEDs like the 250Watt BlackStar w/3 watt chips should last several years. I have CFLs, LEDS (a few types) and a switchable MH/HPS system. What I use depends on where I'm growing. MH/HPS generally get too hot for most closet grows so a combination of CFLs and LEDs are usually your best bet. That's the example in the pics.Attachment 290055Attachment 290056Attachment 290057
Plantguardian Reviewed by Plantguardian on . My grow closet. I'm growing nine plants with two florescent lights. The brightness of them are 1570. The light appearance is warm at 2500k I use miracle grow soil and I use mircle grow fert. I give them 24 hours of light. I keep a nice size fan in the closet. I usually keep it on low but some times turn it up to add more wind in the plants. (I call it "exercising") this is my 1st grow but I have read lots of post and info about. I plan on upgrading and purchasing everything in due time. My plants are around Rating: 5
