you will probly just get a few nugs if you flower now , I put up a picture of one indica type thats only a couple feet tall but I might get an ounce or more from it. keep vegging if you want a yield. you can just tie the top down and grow more branches like I did. flowering will be about 2 months, 7 to 8 weeks, avg about 55 days, but you really should look for visual signs and the smell to change ripe then almost rotting. just about every strain has early harvest windows, you can sample some after 35 or 40 days if the plant is big enough
