Opinions on dehumidifer

Don’t duct your dehuey outside or it’s pointless. That hot air coming out is the dry air the dehuey is making, if you route that outside then your just blowing your dry air outside. literally no reason to run it at the point.

Buy a 70 pint they only kick in as much as they need to and it might be like 50 dollars more for the bigger unit. Facebook marketplace always has used ones. You should know the newer units are called 50 pints but they are the old 70 pints. Also dehuey are usually rated for 80 degrees and 60 percent humidity, when you see high temps and high moisture rating that means it was tested under conditions that were more favorable to putting out a high amount of water. Usually they are rated this way for flood remediation where the house is saturated and they can heat it up real hot and suck the moisture out of the everything. If you were to run the same dehuey under normal conditions 80 degrees 60 rh it wouldn’t remove near as much water as it says.

Different in EU… but it sounds trustfully.

Yeah, it will remove moisture but will pull air in from outside the room while doing it which causes it to run more.

Found out already the hard way.

Wasnt tryin to give bad advice. Just tryin to reduce heat myself.

Sorry for the shitty advice

My grow is a 5x5 with a 600w hps . I was informed that I could possibly pull 5gal of water a day when plants get fairly mature. The dehumidifier I'm looking at is rated to pull 4gal of water in 24 hours under 95° and 90% RH conditions. It's rated for 2500 sqft. Is this sufficient or is it an over kill for a 5x5?
I think a unit like that would be too big to fit in the 5x5 with your plants. 2500 sqft is the size of a house.

It will collect water but there is no benefit, your basically using an 800 watt exhaust fan. The dry air being released out of the dehumidifier needs to go back into the room, it mixes with the air in the room lowering rh, and then gets sucked back into the dehuey and removes more moisture until your humidistat hits its setting and turns it off. If you blow the dry air out the window it won’t bring down your rh at all if it does it’s because it’s working like an exhaust fan, at that point you would be better off with an exhaust fan it uses less energy.

Don’t worry about shitty advice I at one time thought the same thing would work. Best bet for tents is to condition the air in the room the tents in. An ac if needed and a dehumidifier in the room. Then your exhaust fan has a steady supply of cool dry air to keep your temps and rh where they should be:

Appreciate it.

Removed the home made duct and turned up the a/c this morning.

Get one bigger than you think you need I went with one the right size and now I have to buy a bigger I would get one as big as your budget and space allow you can always turn it off for a few hours if RH too low

If the plan is to run sealed with CO2, you need enough ac or dehumidification computed into your plan. Your issue is usually why people get minisplits. A dehuey heats up the room while removing water, so it needs more cooling to cover that, and an ac unit is designed to do this already, thus....

Man, always something else to learn.

Appreciate the advice. Time to research minisplit.
