When your using T5'S, HO OR VHO's, your Auto's will do much better if you keep the 6500k from start to finish. I wouldn't worry about buying the 2700/3000k bulbs unless your going to run photo's. Also keep the light on a 20/4 on/off schedule. Never flip to 12/12 on Auto's in any light. 

I'm running a 2015 blackstar chrome 270w led and in flower I add 3 105w 2700k cfl's. I'm seriously looking to add some t5 HO or VHO's. I'm thinking that would make a good mix of light. Anyone know of some sites that have good deals on T5 lights and fixtures? I'm thinking that a couple 2' 2 tube t5 VHO's would be suitable? BTW again great, great thread!
