Watering cannabis is about patience and timing. Give your medium a few days to dry to at least 2 inches from the surface.br>
Soil: When watering your plant, wait until at least 10% run-off water drains out and stop watering.
Organic/Super soil: Should never be watered to run off, as it washes away nutrients being held in the soil.
The ideal time between watering is 2-3 days, in late stages plants can need watering almost daily. This can fluctuate according to your environment.
