Mystic has been on my list of to do's for a long time.

SOG or SCROG ?

SOG sea of green. It doesn't really make harvest bigger. Sea of green is a continuos harvest of once a month or every two weeks.

SCROG. Screen of green is maybe what your looking for to icrease harvest. More veg time means more at harvest.

If it is the indica dominant I have heard of it is short and stout and will not do well with a screen of green much like northernlights. More veg time will make up for that and you will end up with little xmas trees.
