Does anyone know what small ac unit to put in a 5x5 grow tent

Don't put in the tent. The air coming out the AC will be 30 degrees colder then the tent temp. Way to drastic of a change. Put the AC in the room that the tent is in and let the tent draw in cool lower humidity air. The AC will keep the room around the tent buffered. Just make sure your fan is changing all the air in your tent every 2 to 3 minutes

I have a timer coming in the mail so I can have my intake running for 20 min then off for 40 min do you think this will help keeping the temps down also?

Your fan should be moving air all the time. That is a bad rookie mistake. The plants will drink all the CO2 in the tent in minutes. Without enough air moved to exchange all the air in the tent every 2 to 3 minutes they will grow loose and shitty for sure. Also your letting humidity spike for 40 minutes out of every hr

I have my exhaust on a timer the lowest setting and it takes all my humidity out from 75% to 40% and my humidifier doesn’t keep up!! Fuckkkkkk lmao

I run my fan on 2-3min off 10mins
You need to monitor the temps and rh and adjust the times to your specific needs.

A real controller instead of a timer is what you want. And if you're in an extremely dry environment you're going to need a humidifier with at least a 2 gallon reservoir in my experience, unless you like filling twice a day.

I use the Vivosun grow hub with the Vivosun app and it is awesome. There are other good ones out there as well

Hang two of these up and didn't worry about CO2 at all. I let the exhaust fan completely shut off if it wants to. I never shut off my 5 recirculation fans in my tent though. Ever.

Thanks the left one is a northern lights auto, the right one is a really vigorous pheno of Royal cookies, 22 days into flower.

Have you measured your CO2 by chance? I know a guy that's been growing for a while and he said the bags do work but you should use twice the bags they recommend. I need a CO2 monitor to quantify though so I really don't know. Just took his advice lol. His plants are always so awesome!
