I set up a little veg/clone area to hopefully hurry along my next set of flowering plants, its got an 4 bulb x 4ft t5 fixture with all blue light in it, and also a 50cfm exaust fan on top and im using a passive intake.. seems to be staying pretty cool, and its mostly light proof.... mostly...
here are some pics...
Oh and btw looks like it wasnt burn on those girls at all, stealth panda i think was right about deficiency.... So now they are back on full strength nutes, hopefully this will help..... I will have pics of the ladies a little later.
