I am looking for an efficient, non-electric dehumidifier for the grow room. Do you think one of these would work? Can you recommend anything specific? Are they effective? About 30m3 total grow room volume.
That aint gonna do anything for you man, be useless after a few hours. Used them before in cars and house and they suck.
With a 30sqm grow room you need a proper big dehumidifier with a humidistat and a large reservoir - for the price you would pay over time buying 500 of them cheap shitters you would have a great dehu unit.
You arent dehu a normal room like those disposables are made for a snall space that isnt full of sweaty jungle conditions.
Well it depends man. Donyou really need to dehumidify?
Typically people tend to have to add a humidifier.
Sure that product will suck out humidity but then you’ll have to re introduce humidity.
Honestly unless you’re running above 60% constantly I would not bother with dehumidifying the air.
