I haven't heard much about the T5 fluorescent systems as of late.
Do you still look for the same split: 2700K for flowering and 6400K for vegging? Or as close as one can get. Also, what wattage is considered optimal? 100W total per plant as with CFLs?
Finally, do people mix the two Kelvin ratings in a single, say six-bulb fixture and use it for a full grow cycle?
