he was talking about before harvest, so there would be no chance for hermes as it would have only 72 hours to develop before it was killed. would that not be correct?
Right, I get you. I thought he was referring to the topic (24 hour dark before flowering).
I have left plants in the dark at chopping time before. A couple of harvests ago, I chopped half my girls, then got called away before I could finish. The others were in the dark for a couple more days, before I got around to chopping them. One thing I did notice is that they felt a lot more sticky to touch than the earlier ones. I'm not sure whether there was any increase in potency though.
I have heard of a few experienced growers swearing by this method, and others saying it does nothing. I have no opinion, other than the fact it makes them stickier.
