i know it says 88F but they look cold man. like, cold roots man. feel the lower leaves, feel the lower portion of the containers..are they cold to the touch? what are your nighttime temps?
you don't want more than a 15-20 degree difference in day/night temps (aka the DIFF) , ie: 88F days, so like max lowest night temp would be around 68 F. For me, i like my days around 75F and my nights in the mid-60's F. Some of my peers like it a little colder or a bit warmer., which is a whole 'nother debate/discussion. the goal is have a low DIFF number.
and like the other guy said, your humidity should be around 50%, with plenty of good airflow.. if your RH is too high, then upgrade your exhaust fan to a higher CFM.. if RH is too low, then put a bucket of water in your tent. a tent is such a small environment, it shouldn't take much to effort to raise/lower temps and RH.
when fully zipped up, the walls of the tent should be sucked in a little bit. yur interior circulation fan should be on all the time, and the exhaust fan should be a stronger (higher CFM rate) than what's called for, for your tent size. ie: a 1m2 tent, use an exhaust fan that's like 400cfm or something like that. And don't just vent out to the room the tent is in, punch a hole into yur attic and attach your ducting to exhaust to the attic, or vent out a window. draw in fresh outside air at a low point, exhaust air out of a higher point in yur room. ie: floor and ceiling points.
and when it comes to watering man, Always water to point of run-off man. then lift up a fully saturated container. feel the weight. then lift it up a few days later. feel the weight. when it's not heavy, then u water.
u can also use your finger. stick yur finger all the way into yur medium,. if the dirt is damp enough to adhere to your finger, don't water. if it's dry, then water.
now if your medium is super dry it will be hydrophobic at first. place the pot into a 10/20 tray, then water it, it will run right out, but leave it sit for a while and the medium will wick up the water in the tray and eventually the entire medium will be evenly wet. then place the fully saturated pot back into the tent.
hope that helps man!
