I'm new to this, but I'd like to share my setup with you. It's taken me a while to get it right, but I'm getting some good results.
I'm growing in two canvas grow tents in my garage. One is 2'x4'x5' for flowering and the other is 2'x2'x4' for vegetative growth. The big tent has a 600W LED and a 300W LED. The small tent has a 300W LED. There is an intake and exhaust vent through the portable AC unit's window adapter. There are 4 fans running at all times. A 600 CFM fan with the filter on the intake pulls air out of the big box and the little box because I have them connected with 6" duct. There is an upright fan in the big box which distributes the cool air from the intake duct. There is a pusher fan on top of the small box and an inline 6" fan in the duct from the AC to the big tent.
Inside the big tent:
The most difficult part has been efficient temperature control. I'm pretty proud of my solution. I was basically cooling the whole garage with a portable air conditioner even though I had the AC ducted into the tents. I had to set it much lower than tent temperature because the temperature sensor for the AC unit is internal. I now have temp sensors in the tents and I programmed an Arduino Nano to trigger a solid state relay which controls household current to the AC unit. So now the AC only turns on when the tent is warm and I don't have to cool the whole garage.
This is the Arduino and an LCD to visually monitor temperature and humidity. This was just testing. I keep them at 75-77 degrees.
This is the SSR which triggers on a low current 5v signal from the Arduino based on parameters I control. It's screwed to a heatsink (which never gets warm with the AC unit's current draw) and zip tied to power strip.
The duct is held to the AC with hard drive magnets and painters tape.
I'm currently trying to regenerate a plant I harvested, grow two seedlings, and one clone here:
Here are my results:
