GLUE GELATO... CMH GROW

day 21 and this plant is so far the biggest in the garden added another 315 bulb to make it a total of 630 cmh watts gave it the first nute feed this week handled it good no burn or problems lst the main stem working on my canopy a week earlier then I usually do only problem is my daytime temperatures are 88 even one day 90 degrees and that's with my air conditioner all the way up high and exhaust up on high, the plants are handling the heat ok in my garden but with my a/c on all the way up and my exhaust fan and other fan on I don't know what else I can do to lower temps in my tent
