I have a shelf with 4 T12 - reg cheap ones. But most of what I have under it is small seedling some almost touching the tube.
I was considering a T5 from the hydroponic store. 2 tubes 2 ft 67 $. need to check the other store in Queens.
Was wondering if they would provide enough and save me ConEd $$$.
The photo store has also some bright CFLs 250 W equivalent for 7 $.
Wondering if they are realistic in the output. I do not have a light meter anymoree. WOuld be good for testing all this stuff. Anyway for the winter my Ansellia africana will be on my window sill as it is getting too tall...
