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.
It depends on which seed you have. Generally seeds take between 7 and 14 days to germinate. There are of course exceptions, some varieties can germinate within 2 days if conâ¦ditions are right, where as others can take literally years to germinate - even if conditions are right. 15 people found this useful.
