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 time from germination to harvest depends on the variety of carrots. Baby and globe carrots, such as âLittle Fingerâ and âOrbit,â mature the quickest and are usually ready for harvest within 52 to 65 days of planting. Chantenay, Nantes and Imperator types mature in about 70 days. Danvers types take the longest and typically mature within 75 days.
