I have this lighting system here http://www.amazon.com/gp/product/B006N6TU/ref=oh_details_o07_s00_i00?ie=UTF8&psc=1 I just had some seeds sprout. The light has 4 bulbs in it. 2 red, 2 blue. Should I run all four now? Or should I run just the red and switch laterr? Would it be better to just run reds or to get more light from both sets?
The light is shit... trust me, you really need the lumens to grow canna, and these 2ft jobs are junk, leap to the 4 footer, with 2-8 (54w) tubes aboard. This is ideal but the .....price? http://www.amazon.com/Evergreen-Fluorescent-Light-Lamps-Installed/dp/B005IYOUCW/ref=pd_sim_sbs_lg_56 See the blue light(cool white 6500 kelvin) makes canna grow horizontal, where as the red light(warm white 2700 kelvin) makes the plant grow vertical ...google or do your own tests, run all colors in veg, but once you hit bud change one of the blue tubes for a red
