testing and dialing in my veg tent, need some help

DemonTrich said:

ok, i turned on the lights in my veg tent this friday with my old CG's help. here is what i have working with to give you an idea of whats going on. the tents are in the basement. ambient basement temps are 66* +/-2*. basement intake and exhaust are pulled from ambient basement air. intake air is opposite side of tents than exhaust air. ive done 5hr test runs and stays stable at 77*. used another temp gauge and reads the same temp (eliminating a possible faulty temp gauge).

tent: 4x4x7 secret jardin dr120 (dark room version) w/white panda film floor (comes black from mfg)
600w apollo XL cool tube hood (dimmable, digital ballast) 100% power
vent tech 6" 440 cfm cfm fan pushing air over an XL a/c cool tube (duct/fan/duct/tent/duct/cool tube/duct/tent/duct) w/speed controller (full/100%)
6" 250cfm booster fan (fresh air inlet) lower hole enterance
8" 500 cfm booster fan (exhaust) roof hole exit
one 5" clip style fan inside tent (i have a 2nd, but need extension cord)
temp/humidity with high/low memory.

i have the hood fan on 100%, lights about 1.5-2' from temp/humidity monitor (monitor placed ditectly under hood/light). temp are stable at 77* +/-1*. humidity im not worried about yet as i have NO plants. still testing and dialing in. now if im hitting 77* w/o plants, once i add plants, my temps will raise correct? i have decent negative pressure in tent as well. im wondering if my current situation will be sufficient or do i need to change something up? im getting my clones next weekend, and want to be ready. this is the last thing i need to work on, besides the flower tent, which im still a ways away from running.

thanks guys

I can also add, that even though, outside temps [CNY] were humid, higher 85 one day, 95 the next, then 67 the next...
My basement stays around 62 night temps on floor, to 68 f at ceiling... never goes over 70 even on a hot day...
It is an unfinished dirt/gravel floor... in my 106 year old house...

thanks everyone for the help. i like to plan things out before actually getting the kids in the tent. little to no surprises is my goal. even tho Murphey's Law is never far behind.

i live in a ranch style condos (4 long per unit). im in a middle unit with 2 neighbors on either side. my basement always stays 65* or lower no matter what month. i only have direct sun light on the front of the condo, no other sun light intrudes in my condo, even with all shades up, and my grow is on the opposit side of the direct sun light side. also, my condo (enev on 90*+ days with all windows shut/shades drawn is 77* w/o air on. its nice and cool in the summer and warm in the winter. so im not worried about summer basement temps.
