I live in the Mojave Desert. We rarely get over 20% humidity and we usually idle between 14 % - 16 %. So far my plants have done just fine. You can see them in my sig.

Thanks, I will take a look at them. Did you do anything to raise the humidity while they were seedlings?

Yes when I start seeds I use a little Burpee Greenhouse. It is just a opaque plastic bottom with a humidity dome. I put the seeds directly into Sunshine Advanced Mix #4 and then put the little 3 oz cups, water then and put them into this with the humidome closed. As soon as the seedlings peek above the coco I put them under lights and lightly vent the hood. I try to have the humidome off them by 72 hours after they erupt from the dirt.

When I clone I don't use a humidome. So for only 108 hours, which is 36 hours for the seeds to erupt and then 72 more hours to gradually remove the dome is the only time throughout their entire lifespan they have artificial humidity. So far this has worked.

Good luck with your grow,

I also need help with humidity... I was just gonna roll wit it an hope for the best... Mine varies, somtimes low of 16-20% and sometimes high of 50-60%.

Will this fluctuation do anything?

$40-60 cool mist humidifier. You need to use distilled water only so the calcium in the tap water doesn't stain your plants and furniture with white gunk. Where I am it's a plants paradise at 50-60% humidity most months, but some months I got down to 30% and the cool mist near the grow room or in it works great. Cheap to run.
I don't know how the hell anyone grows decent plants in 20% or less humidity like curious2garden, but in that range your plants are not growing to their full potential.

Yes, constant RH fluctuation is not good. Gradual is fine. You want 40-70% in veg, the higher in early veg the better, clones need 75-90% first few weeks. And flower 40-50% until the last week or two where low humidity helps flowering plants finish.

hey at least its not high humidity. thats way harder to deal with. you can just place buckets or bowls of water in the grow to raise it.

16% is a lil low for flowering.(gonna water more depending on pots) In winter your gonna battle raising humidity. Ive used wet towels hanging under a 5gal bucket full of water to wick up with a fan blowing behind really gives a boost.
Use bacteriastat solution for humidifiers when u do this to keep towel from going fowl.
And if u run a humidifier also you should be able to dial it in somewhat to keep % up as high as your growing desire.

You are right. But then again this is only my second year growing so my plants wouldn't reach their full potential anyway because of rookie mistakes. It would rapidly get out of control for me to start trying to add everything at once. So I've been learning to grow by adding layers. I started simple and gradually add and improve.

One day I'll be able to get the utmost out of my plants but I'm still away off. I figure I'll be ready for a humidifier when I seal the room. But I'm far from that. However my product is TERRIFIC for me and I'm growing to reduce my Morphine and so far it's working terrifically. So you're right this will one day be something I'll look at tackling but for now I'm lucky it's not necessary, my harvests have been way more than enough and it's been amazingly potent!

I've been very lucky, thanks,
