how long does the ice last for thank for the help

This was in the post...

"This small unit with this setup can last 2-3 days at a time 24 hours a day. The bigger the cooler and better can last longer before needing a refill."

Hellof an idea!

Damn, Filthy...you are Da Man on projects like this. Think I'll build a few of your project ideas just for the hellofit..being too hot isn't something we worry about this far North!

I used to think I didnt either being like 4 hours from canadian border but its been over 100 F for almost 2 weeks here.Either way this isnt a full a/c replacement but can help solve some hot little situations.Time lasting depends how hot it is around the cooler what size you use and general variables.If its outside a grow box like in your regular house and itslike 70 in the house and your venting into a grow box it lasts the longest..If its in a large hot room then a day maybe .Have fun buildingstuff like this is a fun hobby of mine.Check the other posts out.I posted the 30 minute 6 site aero build.I posted how to make the 28 site aero setup I use.And Im going to post up my $25 extra wide coverage light reflector 1 or 2 bulbs

Where do you get the dry ice, and how much is it?

I get my dry ice at local Meijers grocery store.Super wal mart or sams probably has it maybe costco.Look on line for local supplies in your area.5 lb blocks cost like #1.28 a lb so 6-7 bucks

heres a dry ice store locater link {dryicedirectory.com} You should find a store near you. PEACE

Made too any scale for from your great idea, imagine the spaces we all could cool!!!

Hey, I built this thing just for fun last summer when you posted it. It does work exactly as you state. The only real problem is replacing the dry ice @ $7 a day for a month could be $240. Might as well get the swamp cooler for $150, and not waste gas going to the store everyday. Thanks for the idea though, I had fun building it.

maybe someone could use it but it sure does sound like a moneypit...lol

The main use of this kinda thing is for the small grow box user.I find it works best if the cooler is outside the grow box where its cooler then the fan is vented into the grow box pumping te cool air in. For big areas itll take a ton but can be switched to use frozen bottles of water and fil the cooler about 1/4 full of water.It will add humidity but will be the same a s a swamp cooler and no cost to freeze old water bottles just have a few extra freezing so when the others are thawed you can swap them.Its a small fix that can help on extra hot days
