    Default Has my dehumidifier killed my plants

    Was having trouble with humidity so I decided to get me a dehumidifier after using it for 24 hour it seems to have sucked all the water out of my plants can these be saved. Also has anyone got and help on using the dehumidifier I’ve read a few places to only have it running on the night cycle. Click image for larger version.

    I very much doubt it's your dehumidifier but if you're sure then water your plants and slow down the dehumidifier if it has the settings..if not remove it from the tent and use it to remove moisture from the room the air is getting pulled into the tent from, you should be golden

    Why do you say you doubt it’s the dehumidifier everything was fine until I put that in there and turned it on.

    Because when I look at the medium in your pots they look saturated..which means the water can't be getting pulled that fast, however, I could, of course, be wrong so following the other steps I outlined may help and to be on the safe side

    I'll just jump in and ask is the air coming out of the dehumidifier aimed at the plants?
    And just one more thing I'll add is I went to a dedicated hydroponics store last year to purchase a dehumidifier after getting bud rot and the lad behind the counter pulled me to one side and said he's going to lose a sale here but went onto explain how dehumidifiers are really bad for growing something to do with cell walls or something to that description and that using the oil radiator I allready had during lights off is more beneficial, now I've got that dialled where temps don't change between lights off and on my RH never goes over 50
    Just my opinion ofc
    Atb chap
