Hello there. Can you tell me why you will put them in the dark for three days? Just learning right now and am curious as I have never heard of that.
Ok this is an article or post I read a long time ago and kept.
1) Darkness increases resin production.
During a plant’s dark cycle, respiration is in full swing. The light during the day provides the sugars/energy during respiration in the dark for growth of many things including trichomes and the oils inside. This is a normal process during flowering. When a plant is maturing and pretty much done, you shouldn’t see many, if any, clear trichomes forming. This is easy to check and don’t hold your breath waiting for more trichomes to form when the plant is finishing in those 3 dark days.
2) Darkness increases terpene production.
Terpenes and other secondary metabolites form mainly during the dark cycle.
3) Terpene levels are at their highest at the end of the dark cycle right before lights on.
Heat from the day evap’s volitle terp’s off we can smell so it make’s sense the highest levels would be when they are forming during the cycle with the coolest temps.
4) Sugars/starches recede from the plant to the root zone while in dark cycle resulting in a better tasting/burning bud.
This is also a normal cycle when the plant is growing leaf and photosynthesizing. At the end of the plants life there shouldn’t be much of anything going on if the plant is truly finishing. It’s a good practice for sure to cut during the dark cycle to gaurantee she hasn’t sucked anything up during a day time chop.
5) Chlorophyll isn’t produced/active in the dark and existing chlorophyll begins to break down.
This happenes during the drying period anyways
Now lots of people will say bro science or voodoo but I do everything I can to make my weed smoke better and taste better and hit better so its up to you. Hope that helps
