Anyone use these lights? http://www.lightsofamerica.com/Categories/Specialty/Fluorescent/Grow%20Light.aspx They are 17w "Grow Lights" from Lights of America they do not list a color on the package or the website, got one at Wally World for $11 to check out. The Tube is marked 7800K they give off a nice orange-ish light with a lil bit of purple tinge to it.

hi, im currently using a 45wt 6400k cfl bulb will plants still flower under that bulb? im growing some GOM's

Started with 150 w blue keeping 2-3 inches above cola. At 5 weeks I added a 150 w yellow and another one at 7 weeks on the side so the bottom buds get light. I also rotate it 90 degrees every day.

CFL LIFESPAN
I thought I'd report what is happening with my CFL grow box. I built a box for my first grow about 6 months ago. It measures appx. 16 x 48 inches and has an OSB board with 27 cheap fixtures mounted on it and suspended over the plants. I run cheap ( abt. $3 each) 23 watt bulbs using a mix of 23k and 65k spectrums. This system has been working quite well, however I noticed a couple of weeks ago that the temperature in the box was a few degrees warmer that in the past. This trend is continuing. While it used to hold around 80 degrees, temps are now around 90. I'm thinking that while the bulbs may be still putting out nearly the light they used to, it's likely that they are drawing significantly more electricity as they age. Time to pay the piper and shell out $80 for new bulbs.
