lighting: cfl bulbs or t5 tubes ??
I am going to invest in supplemental lighting for my Windowsill area where I grow my orchids. I have done alot of reading and still can't determine which is better - a 'spot' light type of fixture with a CFL bulb, or a 2-ft fixture with T5-tube. I don't have a large growing space
so don't need 4-6-8 bulbs or tubes. 1 bulb or tube would suffice for my needs.
Does anyone use the bulbs or a 1-tube T5 fixture ????
