[i have crabs]

i would run them up how you have them for a few months then drop them halfway then all the way down a few months after that, with my par meter thier was no difference in bulb output after 2 months so im gonna probably wait 4-6 months before droping it down, trust me even all the way up you get alot of light,when i had it close to the bottom of the legs the temp did raise a couple degrees in the day so i dont mind having it up a bit anyway
