Questions Do Evaporative Air Coolers Work?
I just saw that in my local Screwfix they sell evaporative coolers as a cheaper alternative to portable air conditioners.
They are pretty reasonable at around £70 and it only draws 65watts so much better than an air conditioner.
I did some searching and there are more expensive models that hold more water and have space for cool packs etc to.
Looks like they do also increase humidity which I guess might not be too bad if it’s on hotter days as usually the humidity drops a bit lower then.
Has anyone used one of these before? Just curious if it’s a waste of money for trying to cool a loft grow in the summer.
Ah ok thanks for that info.
My humidity never drops below 30 but I assumed that it wouldn’t add more than like 15% rh or something. Sounds more like it’s just a big humidifier if that’s the case then.
Depending on the cooler you go with the biggest tip i can give you is to make sure the tanks are clean I use a touch of eucalyptus oil in the tanks between refills to keep things from going nasty. Also as Viking mentioned, expect a big spike in humidity and never put the things in the tent, they are breeding grounds for mold spores.
I feel like a, like a slice of butter... melting on top of a big-ol' pile of flapjacks... yeah.

@yoshi be very careful, those things pump mondo amounts of humidity out and need really good ventilation. They are only used by ppl in really arid dry conditions e.g 40°c with no more than 10%rh. If you live somewhere that rarely gets higher than 30°c and an rh that sits above 30% these are no good for the grow room as the only thing that'll love those conditions are powdery mildew and bud rot. Hope this helps
