don't defoliate unless there's a good reason. i wouldn't use that to control humidity beyond coincidentally as you defoliate for other reasons..
NobodysBudsanswered grow question 4 years ago
That depends on temperature and where you are in the life cycle of the plant -- See VPD chart i have linked in my profile comment section. check out the other links too - great info to create a proper perspective on how things work in the natural world.
lower humidity around 40% is great for trichome production. Keep that up if you can...
if you can't, don't worry about things you don't control, or if you do, start controlling them
:) Get a dehum/ac/heater combo, lol.. "get'er done" if it is essential for you. Yes, it will be more optimal, but your lights are the limiting factor 99% of the time. if they say you get a "25%" increase doing this (totally made up bogus % to show concept), that's under optimal environmental conditions and microdosing feed and 1500-2000umol/s per m^2 energy, lol...
otherwise, it'll be far, far less than whatever supposed %-increase listed. If you do all that stuff, it's accurate information to go by.

Too late to defoliate?Should i try to defoliate these two auto girls a little more, or is it too late into flowering?
If so, which leaves are safe to remove?
They are approximately 45 days from sprout and have been speeding through their fases, so it's been hard to compare to others schedules

Lack of water or its something else.Did it burn from nutrients, or was it due to a lack of phosphorus, or just because it didn't have water?. It seems to me that it is due to a lack of water, but a lack of phosphorus also occurs in a similar way.😄

High humidityHello. Even with a dehumidifier and a 24-hour extractor, the humidity is still above 70% and one of the plants is almost in the flowering period. Can I add expanded clay on top of the vase to see if it lowers the humidity or putting more perlite will solve this? Thanks.Other. General questions

Extremely slow vegetative autoflower grow. I'm growing Glue Auto from FastBuds and Dark Devil from Sweet Seeds. What is wrong with my environment?I'm currently watering about every 3-4 days, one time just water the other nutes from CANNA at 1/4 strength, temps between 20-27 and humidity about 60%. Glue Auto is about 30 days, Dark Devil is about 1 week. Oscillating fan is always on, extraction fan only turns on when >60%
