and this has been discussed a million times on here, really comes down to what you want. i am a t5 fan and kept over last 2 yrs around 200 diff sps and had luck under t5, have mh now only cause i got a deal on it
I think its important for the T5 users to point out how many bulbs your running just to give people that are scoping this a better idea of how intense your T5 rigs are.
