You know, im not for sure why you would want to follow the vpd the last 2 weeks. I be honest, cause I dont know benefits. I deff dont have a PhD.
But I know I just did... And I also on top of that, ran my buckets dry the last week and made all my leaves that were left die and fall off. I then cut the branches off the plant and hung them for 14 days at 60* and 63Rh. down from 65RH last week. If over 60% rh causes bud rot, then why do we dry out plants at 63% rh for 14 days with HARDLY any air flow????? just saying...
Oh by the way, I didnt have to cure, it was perfectly dried. A lil advice a fellow farmer gave me here and it was spot on! You actually start the drying process while the plant is still alive...
Maybe, just a guess, that when I run my buckets dry, but have 60 rh it drys from the roots up, and from the inside out, EXACTLY WHAT CURING DOES...
See it all goes together for me. I wouldnt run over 50% if your room isnt dialed enough to combat spikes. Mater fact vpd is for dialed in room IMO
Excellent advice and i concur
I dont see vpd being a good thing for perpetual.. I would go with 50% IMO
Yep, its freaking expensive to get it set up right. I try to take a couple weeks worth of thought before getting on amazon.. But I promise you, when you do get to run vpd, you will be sold. Is there a chance for mold, yes most deff, but it requires more than just higher rh. Ive always been one to push the envelope. I went straight to hydro, knowing that everyone was saying, Dont do it, you will get mold.. lol ok I made a joke there... My point beiung that a lot of ppl said, i was stupid to try hydro first, and I would fail miserably. And that was after dropping 800 on a system and other equipment..
Then it was dont run a live res..
Wrong, it worked out great.
Then it was don't run over 50% rh in flower
My answer,,, Hey haters, you were wrong ,,, AGAIN...
So maybe, we should stop telling ppl that THEY CAN'T, and instead tell then, THEY CAN...
That is what is wrong with this world these days, we changing into sissys that play it safe.
Hell my mailman just left a note in my mail box, requesting that I move my mail box off my porch, so the mail man doesnt have to walk up steps, you know, the new trips, slips, and falls protocol... smh...
We are men.
We choose to go to the Moon! ...
We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win....
On September 12, 1962, President Kennedy...
Thats the motto my parents instilled in me...
I dont use vpd cause its easy, i do it cause i want to go to the moon :)
That is a fair assessment, and I follow that, except before c02 my temps were 74 and 65% rh. But im going 75% rh in veg and first 3 weeks of flower with my c02 now. So I put my money where my mouth is...
Hopefully I dont get smacked in it :)
Wouldn't it be better for the additional transpiration that high light levels and co2 offer to have a less humid environment to promote said transpiration?
And I am only talking flowering here. I actually don't mind a little higher humidity in my veg tent with the seedlings along side the larger teens it definitely makes happier plants.
I tend to slow the exhaust fan and let the temps and rh climb a bit.
