We must have total darkness at night for our outdoor weed garden.

This is how they convert light into energy and release oxygen. They are also respiring. That’s right, contrary to the misinformation circulating elsewhere, plants, like all other aerobic organisms, are respiring all the time. We stop when we die, and we die if we stop. Cannabis plants are just producing a surplus of oxygen during the daytime.

During the dark cycle, cannabis plants are not photosynthesising, and continue to respire at a constant rate; they do not just begin to respire when the lights go out.

PHOTOPERIOD CANNABIS

Some outdoor weed can be

sensitive to changes in the hours of daylight it receives. In fact, photoperiod cannabis strains cannot transition from vegetative growth to flowering without long nights. 12 or more hours of darkness is the biological trigger for photoperiod cannabis to bloom. Outdoors, as the nights grow longer incrementally from the summer solstice onward, some strains can even begin flowering when receiving 14 hours of sunlight.
