We just switched from a 6 bulb 54watt fixture (for sale - check the classifies (plotting) (naughty)) to a very nice dual 250w halide w/ t5 actinics.
I know we need to start adjusting the time slowly, and we have. About 2 - 2.5 hours yesterday and today. We are going to increase slowly over the next couple weeks.
My question is how long to leave them on total? 7 hours? Actinics 10? What do you do?
