Light cycle for flowering

[Harleyrider64]

Can I run a 12 on, 6 off cycle without sacrificing quality or yield? My intention is to tighten up the flowering cycle and I believe a 12/6 would shave off about 10 days in a 6 week cycle.

I would say no, they need the 12h dark period, it's what triggers flowering in the first place

Definitely start 12/12 then you should gradually reduce the light by about 1/2 hour each week up until harvest. I like to give them a few days of total darkness and no water right at the end of the cycle to really push them to finish up with as much trichomes as possible. Be careful though, use a green light to check that they don't start producing pollen as a defence mechanism. You should be fine though.
