Hi, I've been trying to maintain my temp/RH according to the recommended values as set by the VPD chart: If I put my extraction on the lowest setting, I get temps of about 25, which means the RH should be around 60-70%, but the problem is it sits around 30%, so I've been messing around with sprayers etc trying to get the RH up, but cant seem to manage to keep the RH up. If I switch the extraction off in an attempt to keep the moisture in the air and raise humidity, then I can get RH up to 60-70 and the temps go to 29. This puts me in the green zone according to the VPD charts, but in this setting, I don't have any extraction on. My question is whether it is ok to sit with no extraction in order to maintain RH, or is extraction needed at all times, which is more "important" in term of plant growth? Cheers
Want to run a humidifier+dehumidifier in my tent where each activates only when needed using inkbird controller, my goal is to maintain RH 75%-85%. Q's: 1. If I were to use humidifier/dehumidifier where would be the best place to install them? Close to intake maybe? 2. Is it pointless to run these when your extracting air 24/7? 3. Is there a way to calculate humidifier size? P.S. I KNOW HIGH RH AND CARBON FILTER DOESN'T MIX PLEASE LEAVE THAT TO ME
