humidity

Hi,
I've read that dropping humidity levels during the last weeks of flowering makes buds create more resin to protect themselves, is this worth doing?
Also can i lower humidity in my grow cupboard without buying a de-humidifier.

Any help would be much appreciated.

im not sure how to dehydrate a room, but i know that you should already have a low humidity in your grow room to avoid fungus or mold, and yes it does help with resin, also use a good amount of Phosphorous, thats all about resin

thank you Bobbyboy.

The only true time I know of that humidity affects resin production is altitude.
