You got to have good ventilation not only to reduce heat and humidity but to supply the plants with CO2 that they need for growth. Your plants are small yet but when they start filling up your space they can quickly use up all the CO2 and growth stalls until they get more.
My basement where the grow room is stays pretty cool and can be around 40F or lower during the winter. Last winter was warmer than usual, (thank you global warming), so the ground didn't freeze as deeply as it can so my basement is warmer this summer. The humidity is higher than usual as well with the wet spring and summer we've had so far and that has me concerned about possible bud rot if the RH remains as high as it is. Hoping for drier weather come August when it usually gets quite dry.
When I first looked at buying this place that grow room was a cold storage room the previous owner had built and lined with shelves. He had built the shelves then spray painted and that's why there's brown stripes on the walls. Already had two 4" ventilation pipes built in and I used one near the ceiling with a fan I took out of a dead microwave to be my exhaust and the other that exited near the floor to be the intake. Worked OK for a 400W or two but wasn't enough when using a 1000W light. About 6 years ago I finally got around to cutting a 6" hole thru the stub wall at the top and installed a 6" inline fan so it works a lot better now. I have a Temp/RH controller and a speed controller on the fan so it only runs when it's needed and not all the time and does the job at half speed.
Are you renting or in your own place where you can cut a hole for ventilation or even make holes in the closet door top and bottom to ventilate? Could buy a cheap door to alter and store the original someplace to put back later. I'll be doing that when I tack the addition on to my room. The door between the rooms will just be a piece of cheap OSB.
One is a revegged AK47 plant originally grown from a fem seed from CanuK Seeds.
Three different Kushes. Hindu, Dutch and a bushy little one called Ayahuasca Purple. Clones from a buddy
Four of a cross of Island Sweet Skunk and DJ Short's Blueberry. It's a cross made by another buddy and he sent me about 200 seeds from each of the 5 ISS females he pollinated with 3 Blueberry males. The four seeds I sprouted all turned out to be female and I really wanted at least one male.
Four hi-CBD plants called Sebring's Revenge. Supposed to be 20+%CBD and 2-4%THC. Sativa leaning judging by their skinny leaves. Fem seeds so all came out girls.
I took two cuttings from each at the time of flipping to flower so I would have at least one of each so if any plants are really worth keeping for breeding I would have a copy to use as a mother. All but the AK47 are new strains to me so will have to sample them all once cured to see which are the best. I'll be running Beam tests on the CBD ones to see which as the better colour response that hopefully indicates higher CBD levels.
Just put all 24 rooted cuttings into small pots last night and have them under my DIY LED fixture in the spare bedroom with a Hindu Kush grown from a cutting I took off the original clone. May stick it in a large pot and put it outside to see if it flowers out before the snow flies or frost kills it. lol
