Try hitting them with a little extra UV light towards the end... just for the plants that are finishing up. That's the only proven method for increasing resin I know of.


It got me to thinking... during the last 3 days of darkness, cut on the UV lights only, for a couple hours per day or however long they're normally used for during a light cycle. Dunno if that would do anything more or not than just pure darkness.

If that don't work, cast a magic missile at the darkness and have a mountain dew.
