Going dark before harvest..

Hey RIU,

My female is ready to rock and roll. I know most of you shut down the lights and go into total darkness for a few days. How long should I go dark? 48 hours?

Also, what are the benefits behind this? This is my first harvest so I'm learning as I go. This is one topic I overlooked.

Thanks!

IME, a dark period makes a marginal difference, if any at all. If you guys want to try it, it won't hurt anything. Just watch out for mold. Good luck.

All that putting your plant in the dark will do is make a lil more resin production like maybe 5% if that, iv done it a few times and barely noticed a difference from the ones i ddnt put in the dark, and yes keep the fans on.

It's a final push. Plants collect energy while the lights are on. And expend/grow while the lights are off. So... you're kinda pushing them into a three-day grow period. Shouldn't hurt your plants, might help; I did it in '08 and I didn't notice any difference; but it sounds theoretically-solid.

Try putting in your MH light for the last 3 days , keep fans on like normal and keep the lights on... Apparently the MH light can pull out lots of resin from the buds ,, much more than the reg ole dark days before....

You're a madman. I suppose an extended ON period could be helpful if cannabis continues to expend Stored Energy after being chopped.

MH lamps have a slightly higher UVB Spectrum than HPS lamps; and Cannabis will produce additional resin to protect their foliage from the UVB rays. Weed-Sunscreen = Delicious.

my understanding of the dark period was to achieve maximum potency since thc degrades under intense light, or light in general.
