How do you deal with low relative humidity?

[BR2K]

My winter indoor humidity is hovering around 25%...

[FunkyButtLovin]

When mine gets lower than I feel is acceptable, I use a humidifier.

[homegrown]

You could try a tray of water in front of your fan..let the fan blow over the water. It'll bring the humidity up. Used it in my garage grow this summer. Not sure if it will bring it up 20-25% but it will help.

Some folks have mentioned hanging wet towels if you don't have a humidifier.

[JuanHondo]

i hang a towel with the bottom end sitting in a 2.5gal bucket of water...brings RH in the tent from ~30% up to ~65%

[Rwise]

Bucket of water with an air stone, myself I make soup! But here in OK we rarely have low RH,,,,

[GreenState]

I don't bother with dealing with low humidity (I heat with wood) and plants do just fine. In fact I prefer low humidity--less chance of WPM

[Canuck147]

I like this answer - I believe I'm in the same mindset - less chance of WPM I'll use it.

[SoOrbudgal]

Same here i'm not worried about it

[JDU]

My indoor tent was hitting as low as 11% never higher than 25. I have a strong humidifier going now while the next batch vegges & it's up to 40% but I'm considering taking it out to flower.

[WizardsNThings]

Same here. Winter indoor, hovering around 23-28%. So far the plants haven't cared. May try the towel method but if the plants don't care I probably won't bother.

[BR2K]

As always - You folks ROCK! I will start with nothing (don't want to invite WPM) and go from there.

[WizardsNThings]

Last year I did buy a small humidifier for like $35 and put it right outside the tent. It helped a little bit..can't remember exactly, maybe 10%? That was more for the flowering phase but I probably won't bother this year.

[BR2K]

Whoops! After reviewing GWE, I think I'd better utilize one of these excellent suggestions. I'm leaning toward JuanHondo's solution. Snce I will be growing in coco/perlite, I don't want my plants to absorb too much of the nutrients: https://www.growweedeasy.com/humidity

BR2K That's quite low. Where are you in Death Valley?

"Average Humidity
The relative humidity levels in Death Valley fall well below the national average, ranging from about 55 percent at night and 32 percent at day during winter months, from December through February, to as low as 25 percent at night and 10 percent at day during summer months, in June and July.Jan 31, 2018"

I just checked mine here in the sun room, and it is 31% My wife has a number of tropical plants, and they are all doing well. I am in the high desert, and have not had any significant negative effects from the low humidity. Are you seeing a problem developing?

I too, am in the high desert. I can't be specific, for obvious reasons. Let it suffice to say I won't be posting my efforts. I haven't started growing yet but I hope to within a month...Just for personal use.

I was having issues with humidity, RH in my basement where my tent is sits below 30% in the winter and my tent RH was around 25%. Now I'm up around 36% and I've gotten it up to 50%. I now have two small room humidifiers in my tent, now the issue is my exhaust fan sucks the moisture right out. I opened the fresh air vents wide open on the bottom of the tent, that helped. I also tried recirculating the air from my tent back into the basement, I aimed the vent hose back at the fresh air vent on the outside of the tent with hopes to recirculate some of that moisture back in, it also seemed to work. I have humidifier on each side of my tent furtherst from the intake for the fan. The humidifiers are set on halfway, I can get about 48hrs out of 2gals. If I set them on max, I'll go through 2gals in 24hrs but humidity will be closer to 50%. Other than that, hanging a wet towel would probably be a good option too. I didn't try that but I probably will just to see if it helps

[BR2K]

I am also considering trying one or two diffusers, like for essential oils. I already own them.

I have to fully agree with the do nothing suggestions.

A few years ago I controlled humidity using the VPD charts etc.
Bottom line, I had the best looking plants in veg I have ever grown.

- HOWEVER-
There was no effect on the quantity or quality of the buds produced-

Low humidity plants may start slow, but once the roots develop they catch up very quickly.

This was a low humidity/low temperature/low light winter grow:

Good stuff. Nice to try and keep it simple. Growing into the fall and winter here is actually kind of nice because of the low RH. Drying has no mold problems, just gotta be careful with how much leaf to remove and adjust your trimming. What size are the nursery pots they ended up going in? My yields for my last two were about 2 to 2.5oz in 3 gallon fabric. Trying to go higher with 5 gallon fabric, and a longer veg.

[Weed Pharma]

The KISS grow was a 5 gallon nursery pot-
-I've since, settled on using 5 gallon fabric pots-
