Humidity in flower?

[Bud]

It was always my understanding that low humidity was good for flower and not so good for veg? But from what sum of the members are saying that 50 or 60% is good for flower? Ive flowered at 60% myself but thru no choice of my own. I’m looking for a little reassurance that what I learned long ago is still good intel. Thanks

Low during flower is best but air flow is most important because that's what prevents molds and mildews from settling on the plant.

I’ll start flowering stage at the upper end.. 55% and just slowly drop down to 45% the closer harvest nears.

Anything below 70% RH for flower is good...I am on the coast and it is always humid so I regularly deal with upwards of 80% RH and plants still flower fine, just an increased risk of mold/rot/mildew. As suggested above, indirect air movement is beneficial.

30-50% RH during flowering is typically recommended, but it’s all about transpiration, based on VPD. Check this chart out:

Does this chart come in Fahrenheit?

Probably something like it, but there are also lots of F to C conversion sites on the web. You’ll get used to C.
