greenhouse cannabis growing tips

Many folks in northern latitudes start their seeds indoors in April under grow lights and transfer them to a greenhouse in May. Your own schedule will depend on your climate and growing season, of course.

Feminized seed varieties grow very well in greenhouses.

Many greenhouse cannabis growers have fans in their greenhouse to move air around, and even to push air out of a door or open roof vent.

A fan will also strengthen the stems of your cannabis plant by mimicking the effects of an outdoor breeze.
