Use a very fine mister or a fogger to spray the plants and raise the RH. You need to control it to keep the humidity at the proper level. That's how some of us grow big is using high RH levels and either foggers or misters. You will need a cycle timer because you only run it about 30 secondā??s every 3-5 min or there is too much water build up and you can cause mold. It's only good in the vegetation cycle too during flower there is to big of a chance of bud rot or mold.
