Cooling down my 90+ degree room? Please help! Air conditionair recommendation?

Hey RIU I have 1600 watts going in my room and well its 90 fucking degrees! So uh ya I need a AC, probilem is I have no window to vent out of so I have to buy one of the garden AC that dont require being mounted outside, so RIU what Portable AC do you recommend? How effective can these coolers be at cooling say a 8x8 room?

you might want to look into a portable swamp cooler. I have problems with low humidity so they are a double bonus for me.

each 1000 watts of light non vented needs 12000 btus of ac. In your case with 64 sq ft and 1600 watts theres two ways you can do this. 1. you could get air cooled reflectors and run a 440 cfm fan sucking air in thru a nextdoor room in the house seperate from the growroom cooling the lights and exausted to the attic or wherever,just not back into your room.This way youd only need a 12000 btu portable ac unit or make one yourself Window AC converion for an enclosed space - 420 Magazine™ whichevers cheaper in your mind, but you gotta do the diy ac the right way or it will not work properly! If your planning on a sealed room id get a 2 ton mini split or a chiller pricey but worth it!Heat is a huge enemy! with the mini split you could run 2000 watts easy but you gotta add co2 to a sealed room!With all air cooled lights you colud run 4000 watts with 24ooo btu s hope this helps

Thanks for all the info man, yesterday I decided to reorganize my room anyways there is a window now so it will be alot cheaper but my question is the hot air it blows outside won't smell will it?

No it wont its only pulling hot air from the lights not the room, the exhaust does the room.

you have to make sure that your vent ducting and reflectors are AIR TIGHT! and as long as the intake gets no smelly air from the other room, youll be straight. Make sure growroom is sealed and pump in cool air and co2 into it.this way your just cooling the radiant heat from the vented lights,which isnt much. if you can, keep all the ballasts in the same room your intake for the lights is pulling from.its hard to type it! Or if you got the doe just throw a two ton mini split,co2, seal the room and throw a carbon scrubber with fan scrubbing the air in the room to reduce smell. If your looking to do a portable ac or window unit in that window, be advised window units leak smell alot i know from exp. so do portables! you can make a diy carbon scrubber to put on the exaust of the portable ac but youll need a duct booster cuz the ac wont have enough umph to push the air thru the filter. theres so many ways to set up!

those portable a/c units with the hoses will leak smell sometimes. they aren't 100% sealed on the inside. usually it's not much but it can happen. you can put a few sheets of filter on the end of the exhaust hose though. that usually helps. if your lights are air cooled then a 12k unit will be fine. even if you don't air cool your lights out of the room 12k should be enough. 12,000btu per 1000w seems high to me. probably more like half that.

OK, so I'm now getting 82 degrees, I'm getting my 6 inch fan hooked up I'm going to suck out Tue hot air, and ill lppl into a split or cooler

sorry for the confusing explanationlol this miami og is bomb! Cant think straight right now lol

Yea you are right its 3500 to 4000 per 1kw of light. I would go for 6000 btus per light just to have that extra for future lights.even better news huh, now your setup will be cheaper smokajoe! rep to you trich fiend!

thanks. what's rep? i've seen it mentioned a few times on here.

that's the number we always use. 4000 if the light is vented out the room and 6000 if it isn't

Hey thanks guys. this room is starting to be really nice a 4x4 area for veg, and then
my room, first Dwc run but I'm excited!
Trich +rep is a point system that allows you to + rep people when they give good advise etc a point system I'd u will

its the star at the bottom of each persons comment next to "journal this post"

thanks. got it figured out.

If you're looking to not spend so much on an AC get a box fan and put 2 1 gallon milk jugs filled with water than freeze them overnight leave them in front of the fan during light time and freeze during dark.

Ideal-Air air conditioners are beasts...check out Sunlight Supply's youtube channel

Loopedd im going to have to try that! ANd Hydro ill look @ ideal air! thanks!

So hey I saw this

would that work for a 10x10 room running 1600 watts, currently I have a 6 inch fan sucking air out of my room (through my 1k watt too) and going to do the same with the 600 watt

I would personally go with a commercial unit, seal the room, and supplement CO2. Those regular units are far from efficient. You see a lot of complaints about smell...not only is smell leaking, but nicely air conditioned air is getting sucked out as well. One hose...two hoses...it doesn't matter IMO. Some units come with an internal carbon filter so you might not be able to smell anything right off the bat, but unless the unit has two COMPLETELY seperate chambers it's going to exchange air...smelling up an outside area...while costing you money. Kwikool and MovinCool make sealed units, but Ideal-Airs are the most affordable. Some people prefer mini-splits over commercial portable units...they're usually about half the price, they take up far less space, and you don't have to cut 12"-16" holes for exhaust ports, but I personally don't like the idea of having condensers outside. IMHO, a gardener should completely seal their room and supplement CO2 once they can no longer control temps with air exchange alone. There's no point in exhausting an air conditioned room IMO...and you can get away with (slightly) higher temps once you introduce CO2...(hopefully) allowing your air conditioner(s) to cycle (a little) less often.

My calculation (not very scientific)...if your room has standard 8' ceilings...is 50 BTUs per SQ FT + 4k BTUs per 1k watts of HID lighting...multiply by 1.25 if your room has 10' ceilings
