Sure but the pics may not explain thouroughly how all this works. I hope it makes sense. I'll try to give a quick rundown of my rooms too.
I have one room that is approx 14'x9' or so. In this room I have built a 4x4ish room to hold mommas and cuttings. I usually use (2) 4 bulb 2' T5's in there but currently have my diy 400W cob led light in there at about 1/2 power. This room shares the environment from the flower room through a wall with inlet and exhaust. It pulls air from the flower room, and exhausts into the flower room as well. It just runs 24/7 like that with a constant air exchange. If my flower room is 77*F and 45% RH,....so is the momma room. Momma room works just like a tent, but more permanent lol

For the momma room, I use a 400cfm fan that runs from carbon filter, to the first 1K HPS, then to another 1K then exhaust. The room air first gets scrubbed, then cools the lights, then exits out of the room to outside. I have an inlet in the flower room for outside air to come in. This is what I use to cool my room most of the year when Im not running a/c.
I use a 5K btu window unit to cool in the summer months and because the rooms are so well insulated, it hardly cycles in the summer. this has taken me 2 years to dial in the way I want it. In winter, I use the heat from the lights and dehumidifyer to warm the rooms in colder months.
To change over the room from summer to winter all I have to do is take off the cap from the inlet, and connect the ducting from the last light in the series to the exhaust. Takes literally 5 min to do. In summer both inlet and outlet for flower room are capped and I run the AC with Co2.
