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.
The advantages that autoflower breeders report with their plants include: 1  Short life span with many going from seed to harvest in under 13 weeks (some as short as seven weeks) 2  Can be kept short in stature for stealth growing. 3  The Cannabis ruderalis heritage causes flowering after 2â3 weeks from germination.
