So 50 even 60% RH is safe in flower?For temps anything between 70 and 80 degrees is fine. Don't have more than a 10 degree diff between lights on vs off.
For %RH aim 40-60.
Yes but it depends at what stage of flowering. Although I adjust following VPD I prefer to go down to 50 maximum 55% at the end of flowering especially if there is not enough airflow to ward off serious problems. I'll leave you a site to understand what range to stay in during all stages of growth. (I'm not saying you can't get to 60% but I would rather not risk it especially if you have nice big flowers and not optimal conditions)So 50 even 60% RH is safe in flower?
You could let RH rise a bit if you want to.It's day 21, week 3 since you flipped. You just watered all your plants in the morning. Now it's night time, lights flipped off.... what's your ideal temp & humidity %?
I'm looking at 76-78F & 45-47% RH. Is that in a good window?
Right now lights on im at 40. Sometimes I'm running at 37-38%. Is that a problem? Would hate to have to run humidifier during flower.I'd never chase a vpd chart. Higher rh in veg, lower (50 or under) in flower. Just don't go too low.
I think it also depends on the cultivar.Right now lights on im at 40. Sometimes I'm running at 37-38%. Is that a problem? Would hate to have to run humidifier during flower.
