so all marijuana plants have to be in a grow room on 12/12 to bud.even if they are on window shelf or outside?they wont change with the season.outside plants will though

if the sun is 12/12 and plant is in a window it will obviously trigger flowering. It is a hormonal response.

The problem with being inside on a window shelf is that they need 12 hours of uninterrupted dark to flower. I doubt that is going to happen on a window shelf. Interruptions in the dark period will not only hinder flowering, it is likely to cause the plant to hermy.

Plants outside respond to the shortening days and release hormones to trigger flowering. This takes a while though. Even though tomorrow is the solstice, most plants will not start flowering until the middle to late July, finishing in late Sept or October.
