I sometimes wonder how big of a role humidity really plays in overall plant development. I'm sure it has some effect but marijuana seems to be a hardy and adaptable plant. Right now my Stiltons are growing in 26-28% humidity and are doing very well. That's the way it is in the winter around here. Last summer I was growing in 90-95% humidity and those plants also did quite well. I no longer worry to much about humidity. If my plants are happy below the ground then they'll be happy above the ground. And as far as light right now I'm on 24/7 lights just to maintain heat since I went to my diy cob set up and the plants seem to be doing very well with that. Went from combating high temps to trying to get the temps up. If it ain't one thing then it's another. Good luck with your grow and I would like to see you grow the worlds biggest CQ. Pipes
Haha thanks! Yeah we'll see how well I can cater to Milady's needs
lol
As for humidity, I used to be like you
Now, I've sort of relativated that, seeing how my plants reacted to the addition of humidity to a really very dry environment. Not to get lost in the details of it, I had started a Northern Lights#5 x Haze in a very rich soil but she was showing all sorts of distress signs that her nutrition was out of whack.
There's this concept called
vapour pressure deficit, which measures how extreme the conditions are for your plant. Because the leaves need a certain humidity around them to do their photosynthesizing thing, the plant will pump water from the soil directly out of the leaves to achieve that under very low humidity conditions. So the plant gets so busy just pumping moisture, the nutrients in that solution just sort of whizz by the spots they would've been needed and don't get processed. I really saw that in my plant, and it all just stopped when I added some humidity to the air.
Also, a guy I'm following on another forum (growing in no-till soil) actually uses humidity to influence when his automatics start flowering: lower humidity will get them flowering sooner, whilst higher humidity keeps them growing in veg for longer!
That said, I still agree with you that the better the soil the plant is growing in, the less it will be negatively impacted by what otherwise may be considered harsh conditions.
I also am experimenting with regenerating soils my veggie garden, and this fall I noticed how the plants that have begun going mycorrhizal are much less affected by frosts than others. In fact, the roses merrily continued putting out buds, even the leaves took a long time till they finally started showing frostbite lol
So yes, that definitely is true!
Cheers!
