Always in the 20-30% range....Vegged pretty well in my opinion. Now that they are big they are keeping the whole house a little more humid, 30-40%. Might have to turn the dehumidifier on once they start really flowering.
They do look pretty awesome. What temperature is your tent?
75 or less when lights on. 66-68 lights off.
That’s pretty much where I’m at right now, just a little colder with lights on. I’m in preflower now and I’m getting real tired of fiddling with my humidifier. I’m glad I can pay less attention to charts now that I know growing well in low humidity is possible!
Yeah if you have all the time in the world to play with humidifiers by all means play. Personally its never been a major concern of mine. Temps and actually taking care of the girls is more important.
I use a steam humidifier like the one Vicks makes. I keep it on a wireless timer. One hour on one hour off. Holds humidity fairly well at 45-55 percent even with the occasional door opening.
Forgot to say this is in a garage.
Those kind add a nice chunk to your electric bill. I have one that has a nozzle that reaches down into the liquid and just spins the throw out a fine cool mist. I have it on a 15min timer with on 15 off 45 and as I only have a 400W MH going the room stays too cold for the exhaust fan to kick on. That keeps it at a nice 50% for the two plants vegging in there now. Switch to the 600W and that may be warm enough to trigger the exhaust but probably not as the basement where the air comes from is only 48F now and will get colder as our winter does. +2C today FFS.
Just feed less so you don't end up with toxic salts buildup. With low RH the plants can drink twice as much water and twice as much nutes with it. More problem in hydro but I feed hydro nutes in soilless ProMix HP and get it there too if I'm not careful. Can happen in a rich organic grow too especially if hard water is used as the minerals in the water add to the load. I only use RO water.
Check thrift stores or garage sales. I got mine at one of those places and with RO water it doesn't get all crusty inside. Same with my BUNN coffee maker.
