What is the best Humidity?

[Ktrain]

What is a good humidity to prevent bud mold? Is 60% ok? or should it be less

[jon.hatcher]

It should be 60 - 65 % during veg and around 50 % for flowering. Any higher on either and you open the door for pests, diseases, and mold.

Get a dehumidifier or just leave your growing space open for a while each day if your humidity is running too high.
