I looked into MH and its a bit of a art and you have to know your stuff, where as t5 is plug and play and what I've done is set them up on timers, ( back on one, front on one) so I have the back come on then 2 hrs later I have the front come on then 4 hrs later I have the back one turn off, then finally 2 hrs after that I have the front one off ( this replicats sun rise/ early morning with not so intense light, the midday with intense light, the later afternoon/ evening ) and gives a 8 hr photo period
