DARK, DARK, DARK....hells yea guys you want that darkness. Iv done 24 hours,48,72, all the way up to 120 hours of complete darkness. the perfect number i get is 72 hours. after that i notice no difference. Heres the science behind it......... I give her a good watering the 4-5 days before choppin her. 72 hours before i want to chop, when the lights go off i unplug everything. What this does it it tricks the plant into thinking winter is coming faster than ever; maybe even making it think that the sun has died. When this happens the plants "sucks up", or uses all the remaining nutes to stay alive. It uses these nutes and sugars it has to increase thc production exponentialy. It produces the thc to coat and "protect" the buds from the cold, harsh winter conditions. When my lights go off for 72 hours i dont even peek at my plants. When you go three days without seeing them, then see them right before your harvest you'll smile. You will actually probably hop online and try to get my address so you can send me some!!! lol hope your grow works out man keep the updates a'rollin.
