With tent open thats a bit high. Dtw coco in fabirc pots can breathe and will always have good root pressure. So I can handle higher humidity. Soil can be poor level in oxygen rifjt after watering Id think. For example if youre in deep water cultur and your pump dies or doesnt add enough oxygen, the root pressure can increase and gutate in buds.
Thats not super factual just what I gather and asked AI which can sometimes be very accurate. I was putting bags around my pots for pests but it said it will increase root pressure and gutate and it was. So I removed them. It could also explain why my leafs had some issues on some of them at the time mixed with hot and dry environment.
But yea, a 3x3 will do great for absorbing that plants breath and rh and temps should be better. My 3x3 is the easiest to grow in heres a pic. Ive grown in it this my 4th run in it. Idk how dehueys do connected to tent but I see my best results doing traditional way, lung room. I just condition the room to what I want inside of tents.
I think its great to heat up a tent tho. And yea, your room is literally the same size as mine. Be prepared for heat issues unless your home ac is a monster. Ours sucks and cant get are northern home to 75F in summer it gets above that. Also just make note of my advice because of our similar setup, incase you start to upsize little by little.
I dont doubt you can speak for your self and say you wont upsize, upgrade, get deeper into this. But it happens to people often, its addicting and as soon as you become a heavy user if not already, some upsizing may naturally be wanted later. Even if I only smoked and not do dabs only, Id need to grow a good amount still.
Also because this is addicting to grow and you might actually be interested in some care giving. I am willing to to some degree. Looks like you got a window in there so yea try a portable ac if heat becomes an issue. My flower room is the most comfortable place to be in the home ground floor when its 90F out.
