Chemical Weathering. Chemical weathering takes place in almost all types of rocks. Smaller rocks are more susceptible, however, because they have a greater amount of surface area. Chemical reactions break down the bonds holding the rocks together, causing them to fall apart, forming smaller and smaller pieces.
Autos generally are ready to harvest sooner than photoperiod. Most autos are ready to harvest 65-90 days after being sprouted from seed. Some super autos have been bred to grow very big and can take up to 100 days before harvest.
Unlike traditional (referred to as photoperiod) strains, autos donât need any special kind of light schedule to âtellâ the plant to start budding. With a photoperiod strain, a cannabis plant needs 12+ hours of darkness a day to initiate flowering.
