I would not use that Phillips plant light. I used it on some seeds and it only lasted me about 3-4 months being on about 12 hours a day.
The CFL will last WAY longer than the agro light. I'm very confident that the CFL you got will work but don't take my word for it, I'm sure somebody else can chime in on that
I was planning on getting the natural daylight light bulb but I had these laying around my house so I jut wanted to get an opinion. What's wrong with the Phillips bulb?
