ive never heard of anybody getting more than a pound an a half off an autoflowering strain. i think 3 pounds off a mighty might mother that was vegged for 4-5 months. aim for between a half and a whole pound per plant. i believe greenz said you wont get more than half a pound off GG and i know u wont off the lowryder. but sounds like an awesome grow bro. u should end up with 10-20 pounds and an early harvest. have fun
