Hello all, I have a 5x5x5 room in a crawl space. I don’t really have a way to cool room, my first grow was in winter so it wasn’t a problem. I’m pulling in fresh air from crawl space into grow room through a carbon filter. I’m thinking I might have problems keeping room cool enough in summer. Since I can’t install an A/C I was looking for thoughts/input on using a 5 cft deep freezer and installing a elbow pipe out of the freezer door and installing an a/c infinity fan to the pipe and pulling the cool air into the grow room. Any chance of this working or am I too stoned?

Well... at least you're thinking. You'd need a passive vent on the side of the freezer, but.. they do make floor stand AC units that you can just plug and play. However, I don't think your deep freezer would keep up with the volume of air you're going to be moving, and it would run non stop and prob burn up the compressor in a short time.
Thanks for info, unfortunately I never thought about the compressor running constantly. That’s why it’s always good to get input. I appreciate it. Back to the drawing board
Put the plants in the cooler turn cooler off. Lights come on, let room heat to upper end of tolerable range.
Turn on cooler.
Cooler blows cold air directly on the root system cooling circulating water keeps plant cool in hot room.
Cooler runs for 6ish hrs and lights go off room cools rapidly cooler turns off.
Rest for the compressors most the day no fan no new ventilation.
I have no idea if this will actually work but I can't think of any reason why it shouldn't in mild high heat 90-100f.(I might be to high)
Working a set up in a crawl space I gotta imagine humidity control would be a much bigger factor then heat

Unless i misunderstand, why would you pull in fresh air thru a carbon filter?
Isn't the purpose of carbon filters to de-stank the air in the grow space, by pushing the dank stank out?

Usually...before I ran my op sealed, I would just use an 18 wheelers air canister to filter the fresh air.... I live in the country in a legal State, so scrubbers were never used.

Clean air going in. VOCs, odour, spores bugs etc. Filtered out. I run Merv 8 and HEPA filters on all my intakes. Buds stay clean. Filters get dirty as heck over a year's time. That would all be on your plants. Gross!
makes a good case there, bruh.
Yeah it is. Sometimes the air in crawl space can get stale./humid. I have a fan blowing but just use a carbon filter to scrub the air going in and out. Probably an over kill but better safe than sorry, imo.

No it won't work. The cooler won't keep up with the airflow rate.
If you are drawing air from the crawl space then it will no longer get stale. Because its constantly exchanging.
Depending how cool the air is outside , you might be able to just increase extraction to maintain temps in grow space.
If the air outside is already too warm then AC is your only option.

What light are you using?
LED runs a LOT cooler than HID/HPS/MH

This idea will be expensive.
Plants desire carbon dioxide. Dry ice could be a solution.
Cut a hole in the floor above the grow area and place a dry ice making machine there. When a certain temp is reached in the crawl a pellet of dry ice could be dispensed and fall into the crawl through a trap door that closes by spring after the ice falls through.
This one is pricey but if you can automate dispensing:
"The SCILOGEX Portable Dry-Ice Maker is the fastest way of providing a block of Dry-Ice for your needs. It is compact and lightweight, requires no electrical power and is safe and simple to use. Most importantly it is there to give you immediate access to Dry-Ice (-109.3°F) when you need it. The economy of having Dry-Ice 'on-tap' can provide considerable financial savings.
The SCILOGEX Portable Dry-Ice Maker produces a block (not slush!) of approximately 2.2Lbs (1KG) in weight in about 1 minute. Yield from a 75 lbs liquid cylinder - 5 to 6 blocks at room temperature. (Yield can appreciably increase at lower ambient temperatures, i.e. @ 41°F approximately 1/3 more blocks may be produced.) "

Lol. Its not. I was just looking to save some money. But I haven’t spared any expense so far so why stop now

Then refit with LED lights... they use a lot less power and give off so little heat you'll be worried about getting too cold rather than too hot.
I have a spider farmer sf4000. It’s my first grow in summer, not sure how hot it’ll even get. Just thinking forward, I’d like to be prepared in case it does get too hot. My room is in a uncontrolled environment. But the room itself is well insulated and sealed tight. Thanks to all that responded
