Chaweederstarted grow question 5y ago
I have a forced air heater for the grow room/ shed, I have a co2 ppm to gauge if it is safe, usually stays around 800-1800 ppm in there. Is it ok for the girls over the winter in these conditions?

Best Humidifier for 3x3x2 grow tent and best way to set up?I’m about to buy a dehumidifier. Finding one with programable humidity levels makes them too big 4 my tent & the small ones can’t be programmed to turn off when humidity is too low. Can I get a cheap one with no controls and manage humidity with my Humidistat alone? Will it work?Setup. Ventilation

RH too low in indoor grow. Solutions?I'm having a issue with my grow - RH won't go above 20%.
With a humidifier inside, full power. Temperatures are between 21 and 25c and I can only think the air extractor is taking too much air out of the grow, as in the night, with lights and fan off RH rise to +80%. Any ideas?Week 3

Humidity Control TipsWhat is the best way to control night-time humidity? I have my lights-on conditions pretty fuckin' dialed in, but my lights-off time humidity is around 67-68%. My temps are great at lights-off, around 71-73F. I can put a big dehumidifier in, but I don't want to yet. Any thoughts?Week 2

So has anybody used these cordless mini dehumidifiers in their grow rooms? They’re small units that u charge over night every so often when the silica changes colour? My grow room is very small so an electric dehumidifier wouldn’t fit and I’m struggling to keep humidity downSetup. Ventilation
