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's actually a really good question! Every new grower should know how long they're signing up for! The short answer is: from Day 1 of your weed plant's life to actually smoking your harvest, it takes... Time Needed: 8 weeks - 7+ Months.ote: Before you start trying to grow a 6-week plant, consider that it will produce just a few grams of smokable harvest. With a 4 week vegetative stage, the time from seed to harvest averages 3-3.5 months, but the yields can increase from a few grams to double-digit ounces.
