From a fellow grower: I ordered a girls Scout extreme auto flower Package but the plants have already started to bud. The plants are not ready to bud they are too small. This is my problem they are not bigger than 10 inches, they are in 2 inch by 2 inch Square little pots that are used in incubators on my window seal, the lighting cycle is what it is now sun rise 6 am to sundown 9 pm.
I stopped using autos because of their “extreme” sensitivity to disturbances that cause them to flower.
Transplanting or yelling Boo, will make them flower.
I would recommend growing in the pot you plan on finishing your grow in when it comes to autos no transplanting. Just my opinion and experience
