LIST:HELP ME PULL THE TRIGGER(14'x15' room) 6- Flower X 1K+T5's-Veg. 2-Ton mini Split

Here are a couple of sketches.scan0068.jpgscan0069.jpg

I'm all set and ready to go. I tried to order yesterday and my CC was declined because I needed to raise my daily limit. Maybe this is a sign to double check with RIU.......I think so!

So this is a sealed room built inside of a garage. The room is approx. 14'x15'x9' on the inside. I already have a 2-ton Shinco Mini Split and a 10" Fantech 10xl exhaust fan that pulls 1,226 CFM's. The veg. room and flower rooms will be vented between one another via 2 booster fans. This way, the mini split A/C and CO2 can easily work for both rooms.

The grow medium will be coco and nutrient will be manually delivered via a pump and watering wand or similar. This will be a drain to waste. Is a water chiller necessary here or what's the deal in this situation??

I have 2 ports for exhaust outside of the sealed environment at the peak of the garage roof. They measure ~9"-9.5" in diameter. One is going to be used for the main exhaust of the sealed environment obviously. Because it gets SO EFFIN' HOT in the garage during the summer, I was planning on using an 8" 745 CFM inline fan hooked up to a thermostat and switch. Anyone have any other ideas or suggestions??

In venting the Veg. and Flower rooms between the divider wall, I'll be using 2 x Duct/Booster fans. Does 6" 250 cfm's sound sufficient or will it need to be 2 x 8" 500 cfm fans? What is the best way to control these fans so that they're utilized efficiently?

Go right ahead and ask if you have any questions. I know I may have a couple more.

Thanks in advance for the feedback, Ty

Looks good man. What materials are you using to build? also are you insulating? That will help a lot with the heat. why the 2 exhaust ports, are you exhausting more then your lights? Im building the same kinda thing, size is 22X9, curious what your budget is for this

Well, I used metal studs and track and only went up to ~6'8" because I was going to keep the garage operational but then decided against it and went up to the A-frames for a height of ~9' but this addition was with wood...Just made wood track on top of the metal, went and plumbed straight up against the A-frames for a wood top track, and filled in with the wood cripple studs.
Yes, I've insulated so far on all walls and will do the ceiling some how as well.

The 2 exhaust ports are initially there at the peak of the roof just to vent the hot air out of the top of the garage. The sealed room sits below...The ceiling for the sealed room tops out at the bottom of the A-frame. I'm just venting all the lights but was planning on venting the garage as a whole with the 8" inline fan hooked up to the thermostat/switch.

The budget...well, I'll just tell ya that the 2-ton mini split Shinco was a little over $1,200...I got the main exhaust fan for around $400(usually over $500) and this list totals $6,880+ with the shipping. I'm not sure what I've spent on the building materials so far. I also have to budget an initial 2K for bomb ass genetics and then a per plant charge to start...Then there's $1,400 for my electrician running everything...He's building light controllers/timers along with a separate sub panel just for the room.

22'x9' huh...Sounds like a good amount of room. Is it already built or no? In the basement...We don't have those out here in SoCal.

sounds like you know what you are doing man. Hopefully you can get it done without tapping out the bank. I know I am struggling with that. My build is in a basement yes, and is all framed/insulated. Electrical is ran, just need to get the inspector out here before I can seal up with drywall. I was thinking why cant the mini split handle controlling the heat? I have seen grows that had 10+ lights uncooled and the mini split keeps the ideal temps. Is this possible in your situation?

I think you're correct, that the mini split can def. handle the heat. I'm decent at researching but I'm lacking the in person/hands on experience and am just unsure about most things...I hate the unknown! lol I do know that it get HOT as Fuck in the garage though...Hot enough to the point that I don't even want to go in there...It heats up the house too.

what im thinking is venting your lights with hot air is not going to help, I would think since the ambient temps are high you can seal everything and exhaust nothing. Have your ac do the work as long as it can handle. insulating will be key IMO, to keep the cool air in. Just a thought

That's a good point. My intake is at ground/cement level and through a vent that sits in a shaded part just outside the garage...I'm thinking around 100 degrees here some days in the summer. Maybe I should just cut it off once it's that hot??
Maybe all the time.....hmmm. That's interesting...haven't thought about that enough...

I'm just thinking that a 2 ton mini split is going to be costing me a lot since the total electricity will toss me into the upper tier anyways.
