yes it would work, if you did it consistently(thats how we do it indoors, put them in the dark for 12 hours). You would probably going to need to do it for a week or so though. If its not consistent, and you bounce the photoperiod around you can develope hermies.

In my opinion it would be the smart thing to do. I live 100 miles south of Vancouver BC and at the end of September im fighting mold and rain. The faster you get the plants to bud the better, who knows if theyre even gunna finish. Frost is even worse though.
drudown11 Reviewed by drudown11 on . Trick for earlier budding? I've got a 1/2 dozen plants. I'm in southern Canada we and still have about 15 hours of daylight. The girls are starting to show hairs, and to encourage faster budding I've got this idea. I have a little shed that will hold 2 plants, and it's totally sealed and pitch black in there. If I were to put two plants at a time in there at 7pm-ish and take them out before work at 6 am-ish for a few days each, would that help getting them to bud quicker? Just a thought.... Rating: 5
