A/c and room . Need help

Have you thought about splitting the room into 2? Flip-flops 12/12, only have 1/2 the heat created as well as more consistent demand for co2. I used to go this route just to skirt the nosy electric meter maid's questioning, but there are many things to consider.

I picked the wrong time for this set up , wish we were entering winter instead lol but I was reading that you need 4000 btu per bulb alone
Also I'll be running my lights on at night for sure in the summer it hits 65 at highest at night
Also I could dim the lights down to 750 until summer temps are over with..

Well this grow is for 4 people and only going to be a 12 plant scrog . Not my first go round nor a big profit project .. But yeah idk what to do then the room is built with 4x4 studs as frame, plywood for wall and 2inch insulation and I insulated all the cracks in between .... Also lights are not going to be air cooled ...?? Any suggestions on wich a/c will keep the room cool with the lights and everything also the temp will be more like 77-80 (going to use c02)

If the room isnt sealed...i.e... not air cooled hoods and you are exhausting them... CO2 isnt going to do any good... you will just be exhausting it...

He won't need to exhaust externally if he has a/c and CO2. Should help with the stealth.

I wouldn't use a portable or a window unit. They aren't nearly as efficient as a minisplit. Minisplits are what most growers are using in sealed rooms. Plan on 4000btu for the lights only and 6000 btu for lights, CO2 and any other equipment that puts heat off.
 
Yeah it'll be sealed , also I was told that the a/c recirculates the air in room nothing is going to be exhausted @Crab Pot .
Ok so as long as heat load goes im thinking I'm going to need about 2000 btu for heat load ,3500 each light x 4 so 14,000 lights, for the room im thinking 80sft x 20 btu so 1600 btu so I'm looking about 20,000 btu to cool everything ..?? I'll look into mini splits
 
So I looked into mini splits and are defenitly the best opt! But damn are they pricey also ... After 12,000 btu they only come in 220-230v it'll be hard because my panel is in master bedroom wich is opposite side of house .. Very difficult to change my 110 to 220 :/
 
Two 12,000 btu 110v units would work.

Check out Mr Cool DIY Minisplits. I installed a 18,000 btu unit earlier this week that I purchased for $831 though Ingram's. They come prechaged with refrigerant so no need for a HVAC guy. They have a video you can watch of the install process.

I think your safer with 24,000 btu. You don't want the units running 24/7.

Agreed if he uses a mini-split system. But if it is a window unit or a portable, which is what the OP referenced, exhausting is a necessity. Seems there is tons of help here, happy growing STLbudz.

This is exactly what I was thinking ! Just now literally!!! Ok new variable just popped up my garage is only rated at 30amps im going to need more than that atleast another double lol.??
@Mount yeah I think I'm better off with a split for a more dialed room. More $ but less hassle . Good thing this is for four people so maybe 3-4$ on my end phew
 
Man the units are pretty reasonable I like the diy I was thinking maybe to save some cash aswell maybe I could just get the 220v and do this looks pretty simple
 
This thing has 2 garage sections , can someone help ? Can't figure out how many amps I have in garge also if I can raise the amps? I'm thinking of getting the 24k btu and adding a 220 running it down this ,then run it out to the back around to by my garage door where condenser will go ..?

I have a 10x10x8 tent that'll will be running 4000k air cooled hoods with to 8" fans 1 pulling 1 pushing outside room. I know how to set up but never worked in a big room like this . This flower room will be in garage in central cali wich can get 105 outside so for that reason I will have lights on at night . My main Q is what type of a/c is best in my situation ?

Ps I already have an lg dehumidifier

I see you went with building a room ,,if the house has central ac drop a duct in the room it will run when the house runs,,,This is what I did with no problem other then the smell I built a self oping vent so it only lets air out of the duct work not in cost me 30 bucks for a 25 foot insulated 8 inch duct 6 bucks for the vent hood for ceiling and few dollars for strapping,,there my self opening vent made from a 2 inch thick Styrofoam cooler,,,,,Also when I run my lights at night 18-6 for vegg growth ,,day time is then cold in my room like night time would be and this is the hot part of the day,,,,when I flower I reverse this and run my lights in day time with the cooler temps,,vegg likes to run a little hotter and ac will not run as many times at night allowing for a but more warmth ,,works in my situation ,,made a bad arse secret room for few folks

That looks to be a 200amp service, with 4 open slots. That double breaker (space saving breaker) is 20 amps on both sides, 1 for garage 1 for kitchen. So it looks to me like you have 20 amps to your garage at this time.

Now is this a home that you own or do you rent?
 
@MaiNiaK420 rent. Ok cool nice 20 amps should be enough for 1k and all other stuff just need to pull power somewhere else for the other 1k. Yea I uncovered the plate looks like I can add a breaker for the mini split
 
Here's the U scrog need to utilize my space with less light/heat my mini split is coming in monday going to use seal up gaps in between wood/plywood any recommendations? Was thinking caulk or foam gap spray whatever is cheaper ?

STL Budz, I live in the Central Valley as well..... Sweltering heat of 115+ at times. I do my grow in the garage...... I fixed that very problem your are talking about. You need a Double vented AC unit. Something that will pull in fresh air to cool off the AC unit, and the other to exhaust the heat out of the box ( you have to put some holes in your house to get that heat out, and pull that fresh air in.) Once you do that you will have no issues with your AC. Also you will be able to use CO2 now as that ac will not be grabbing your CO2'd air and shooting it out of the exhaust.

This bad boy will work up to 450sq ft room. Its what i use and its amazing. Also I had to run another 20Amp circuit as well. Didn't need to go to 220v. You don't want to burn your house down bro. Also that would put the city on alert and the cultivation guidelines will be more strict.

Put in a split breaker, (take one that is a 20amp breaker and replace it with a split breaker, will do two 20amp circuts) and run another pair of lines to your garage. Find a buddy thats an electrician and just pay him the homie price if they can, you don't want to fuck around with power.... that shit will kill you.
