Other things that will up your cooling amount will be dehumidifiers and CO2 burners. There are other things but I cant remember them all right now. Maybe some other people can list them for you.

Cooling needs also depend on how much direct sunlight the outside wall/roof of the room get's each day. Even when running lights at night, that's still a factor.

I always set up a room and run it "dry" for a day or two and see how things are. Also plants help to maintain temps. A room will run a little warmer directly following a harvest, without all that plant material in there. That's an observation I made from experience and paying attention to temps like it was my job.

edit: electrical work is easy. Color coded and they have diagrams for just about every wiring scenario you could come up with.

for her situation , being in florida & running gavitas (ballast on the fixture )
i'd say 5k btu per 1k watts of light would be a better scenario than 4k btu .
her CO2 will be tanks if i remember correctly , but a dehuey will be needed & they put out some heat too .

so her original estimate of 24K BTU is right on track for what she wants to do .....

agreed. in the south even 5k per light can get a little hairy come august. im a bit above her and if i had my way id do 5k per plus 5 on top of everything. all that is changing though, now that im switching to 630s. speaking of, aspen, dont forget to account for veg lights if you have to.

Yea Dan your right on..... i figured 24k after all the research, and ill be running bottled co2 I just cant see adding more heat to the room with a burner... Ive done all the math and with the Dehumidifier Ill need every bit of 20k cooling, so the 24 should be just perfect, and there is an existing vent from the shop Central AC in the room, so that should help during the hot months, i have been trying to figure out exactly how much help that single vent will help but i cant figure out exactly how to take all the measurements so i can run those numbers with my MINI SPLIT calculations..... Im CONFUSED DAMN IT..... But I'm sure that fucking vent will help out some how! AnyWay....

Yea DTOG...... the office in the shop is on the north wall 10.5x22 the shop is framed with 2x6 and the walls were sprayed with some kind of foam it has OSB plywood on the inside and outside walls outside has vinyl siding with foam backer under it, on the west side is a 45 foot oak and the east side has a pecan tree about 65 feet tall. and the ceiling has 38 inches of blown in insulation. the reason the power scares me is this shop has 3 phase power. And that cant be anything like a slight tingle if i mess up..... If i get shocked in here it will be like an explosion...... that's why it scares me.

The standard is 4k btu per 1k of light. Plus 1k btu cooling for ballasts. So at the minimum for 4 lights 16k btu cooling and 20k btu cooling with ballasts.

I would also say if you are in a hot area you will need a little more. Like say if one of you wall is exposed to direct sun light during the day.
Yup Itchy..... all i have to cool is the equipment and the heat it generates, the shop ac can cover the veg area with some 315's in there. This end is well shaded where i have the tall 9 foot ceilings and the last grow has no shade to speak of.

240 volt is simple as 110 it just burns more. Wear nitrite or latex gloves no worries. Wire it all up before you connect it to power. I have no doubt that you could knock it out with Dan's help. That being said Hot summers fuckin blow as a grower.

But i got big power wouldn't it just melt those gloves.... ill load a picture of the panel box for you guys.... this was a real machine shop to make custom AR rifle accessories.

& thats easy enough i could walk her through that , unless she already has the knowledge .

Your so awesome Dan! we gotta work on this power thing because i damn sure dont have any knowledge and i ain't no electrician!

I have no technical or handy skills. Pieced it all together. It did take a good chunk of a day. But it was worth it. That's a 12k btu. It cools about 2100 at a time max (all open hoods, lung never exhausted). I set it to 70. The lung stays at 72. Tents at 77. I can improve the tent temps by playing with the fans I think

Fun projects lol. Not difficult at all. Easier if you don't have to worry about security as much.

Insulate the ac properly, duct intake and then just seal the back to a piece of insulated plywood over the window.

I had to worry about sound and shit.. my window is by the sidewalk

wow Ill bet that was a challenge..... the sidewalk...... my place is 10 miles from the nearest sidewalk. Think ill get the mini split going I'm so busy now Diving and working..... those post art awesome TT great information thanks so much the math says i need more cooling than a window unit can provide for the moment so looks like i am about to tackle the power issue "not having any power run to the location" that's some real good brain storming on your part buddy my hats off to you!

lol,well this is a good time for some bikini pics then,im sure that and a little sweet talk and a lot of these guys would be driving down on their own dime to do an a/c install for you!:biggrin:

Now Unc...... You guys are to AWESOME for all of that.... you old farts would have a HEART ATTACK if i did that..... and I'm afraid i would miss y'all......LMFAO...... Naha..... no Shots..... Im a MYSTERY.... and besides the pervs that would show up wouldn't be trusted within 5 miles of my shop...... but we could all gather around the shop..All of you that are real friends... and watch, Ziva, Smokey and BO play with the PERVS....... once there on the property..... Can anyone guess who those Three are in my Life? Come on UNC that would be fun.....

Aspen from what I've seen you do so far I'm betting you could self install the mini split. Only issue might be running electrical since anything over 12K BTU is going to be 240v.

Awww thanks RR...... ya know what Im going to try it for sure now. I think i can do it with some Advise. and its a DIY install anyway right.....at least the one i want is....

agreed. in the south even 5k per light can get a little hairy come august. im a bit above her and if i had my way id do 5k per plus 5 on top of everything. all that is changing though, now that im switching to 630s. speaking of, aspen, dont forget to account for veg lights if you have to.

Thanks Nameless ye the shop Central AC can handle 3 of those for my veg area....... and im hoping the extra 4k BTU and that damn AC vent will get me through the DOG days......

thank you all.... Lots of love in the thread...... you Guys ROCK! :biggrin:

If you are going to run bottled CO2 and your central air it may get expensive with lost CO2.

They do make a 24k btu window unit. The one in my picture is a 24k unit. I got it at Menards lumber for around $500. Menards is like Home Depot.

3 phase power is no different than single phase coming into the house with the exception of 3 hot legs instead of 2 ..... its nothing to be afraid of . i can walk you threw any power installation needed & if i can't ... rives is here too :tiphat:

You could do 2 110 minisplits, that way you don't have to mess with 240 volt . Sucks when you can't get the help you need.Rives is the man when it comes to electricity. As long as you connect all the wiring before you connect it to the box it should be fine. I wouldn't personally handle a live circuit.

I just finished doing a self install myself. If you have a friend with a vacuum pump and gauges even better. If not you can pick up a pump and gauges on eBay for under $100. Hardest part I found is bending the lines without kinking them.

I'm thinking she is gonna need more than 2 tons. Remember my last room? I had 2 1/2 tons with 4 epaps running at 660, 3 fans and a dehuey. It barely kept up on hot days. The room was well insulated and inside a larger building that was vented. I should have gone with a 3 ton.

Another thing is I have never seen 3 phase in residential. Are you sure it's 3 phase, and what voltage is it? That will make a difference

that's what I was thinking, why does she have 3 phase power in her shop ?

TT that's some serious dedication I'm impressed.... But I'm not completely convinced can do all that..... What's the smallest ac I can get away with to cool 4 light's. 24k BTU? And my location is already topping 90....... I have to wait for the mini.. I gotta get this right and that alone is worth the time..... And having it installed is well within my skill set... Man I wish I could do that kinda stuff....

sq footage? also convert the 3 110 volt 3 phase to 220watt single phase for the ac unit

commercial building generally use 3 phase 3 110 black common switch legs

3 ton mini split is very common for those amounts of lighting with R 13 insulation in walls. conversion of 3 phase video 220w

The people that owned my place had a company making AR rifle parts. The shop has 3 transformers on its power Pole.... It cost him 12 thousand to bring in the power.....

Dan I'm going to take some shots.... Of the panel box and what needs to happen to get the power worked out. See I also need power for the lights and fans and all...... I'm thinking about the Dx Sound they make custom power distribution boxes, what I'm thinking I will do is run an outlet like a stove outlet into the room and use the power distribution box to run everything... I'll get some pictures so we can get going....

i cant believe you have all that power! im so jealous. im running 4 lights plus veg plus ac and fans ect off 50A (50% of my 100A service) and its tight

So not having the ac yet.... And bear with me here..... I'm thinking out loud, so...... Being inside the shop that sits at about 76 all the time, I think the 24k will be enough AC that office is the coolest room in the shop.... The Mini Split will be for supplemental cooling just for the room...
