Darkness Before Harvest?

Anybody used 2 or 3 days of darkness before harvest? Does it increase resin production?

Heard it has but I don't know for sure, plan on doing it to my plants though just to see.

Yeah but without a GC/MS machine how would you know?

I dont know fully but Jerry Garcia 2007 swears upon 3 days. I do 2 days, and i do notice more resin glands. But i dont have a scale to tell.

I tried the 'total darkness the last 3 days' my last 3 grows ... I noticed zero difference, but give it a shot, costs nuthin' to try ... be sure to keep your fans going though, ya don't want high humidity/mold problems ... :jointsmile:

It would be very hard to tell if there is any real difference. I might try it with a couple plants.

It may not cost anything to try, but it will actually safe some money as the lights get to remain OFF. That is always a nice feeling after having them humming for so long.
If it causes no harm, then it sounds like a benefit. Of course this is a way to advanced method for me:thumbsup:

Ive always thought about just turning the light on for shorter times the last three days. Like maybe put it on 8/16 so you could at least have a little light to cut back on possible mold and keep the humidity down a little. Think this would help or work?

In no way am I suggesting you experiment and try this, but I have ALWAYS done the 3 days darkness, and shove a nail through the stalks. Old wives tale that it forces the plants to push out more resin. I have never NOT done this, so I couldn't tell ya if it works or not. Seemed logical to me....but again, just my :twocents:

A stake through the heart is for killing vampires!
The lights-off thing... There's no reason NOT to, and if you run a perpetual grow and need the space for incoming plants, that's a good reason TO!
As for forcing the plant to push out more resin.. Wives tale. But a harmless one.
