I do 2 days but I’ve heard people do longer even as long as 5 days. From my personal experience I see an increase of resin production, it’s nothing dramatic but to me it’s worth it. There was a study done on this by a medical marijuana institute I believe called SIMMS and they found an increase in thc production by up to 30% after 48 hours of darkness. No change in CBD or CBN. Hope this helps
I am going for a good 5 days as parts are riper than others, fingers crossed
Although they call themselves an Institute and it all sounds very official and scientific... in reality it is just a club of people with hardly any scientific background. They are from the Netherlands and are connected to a club of old time stoners. Fun people and with no bad intentions.
I get what you’re saying but because I myself see the results in my grows I believe the tests are probably true. Not saying you are guaranteed 30% increase like the study says
