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.
How to grow your auto seeds: Auto-flowering plants tend to be small (though there are exceptions, check out Lemon Haze Auto below) and do well in high density grow systems like Sea of Green. They can also thrive in containers, but donât like to be transplanted. Germinate them in their final pots (1-2 gallons works great).
