I don't really understand what you wrote, Andrew. Quick googling led me to discover its a certain type of growing light and that the 6400K is conducive towards 'growing' as opposed to 'blooming' or 'finishing' ...somehow? This is an example of one of the bulbs found from your suggestion: http://www.htgsupply.com/Product-6400K-AgroMax-4ft-T5-Grow-Bulbs.asp Is that what you meant? Also, will T5 bulbs work in a standard fluorescent fixture and are they better for seedlings?
I can buy two 4 FT fluorescent shop hoods for $11 each.
I wanted to mention that I have used a CFL hood setup before to start, but I'm unsure of whether or not the plants were optimally healthy when I started them this way. They were started indoors in an apartment and I did not get to outplant when I had planned, so they stayed in doors much longer than planned. I'm wondering if anyone can share some perspective given the images I've added below?
I have about 16 8.5" lighting hoods and put a 23W CFL bulb into each of them.. Here are some pictures from when I had the setup last time, indoors in my apartment.
