Am I doing this right?
I am new to starting my seeds indoors and have a few questions regarding artificial light.
1. What is the T rating you refer to when describing fluorescent light? Mine are labeled T12. Is it appropriate for this application?
2. I am using three 24" fluorescent fixtures, each hold 1 bulb per fixture with GE 20 watt plant & aqarium bulbs per 72 cell seed tray. They are fixed about 1.5" above the seedlings. If this enough light, overkill, or very inefficient?
3. Is there a cheaper alternative to what I am doing. My entire setup consists of a total of two shelves, both lit in the same manner with three fixtures per shelf. I feel as if I may be creating an unsafe situation, as I am controlling each set of 3 lights with one timer. Both timers are plugged into a good surge protecter. Any suggestions?
