height limitations

Do you just flower before the plant gets big?

Tie the plant down and spread it out.

blow.....you can top your plant and that will help them just become bushier and not as tall, you can lst them and this will also help keep your heigth down (search lst for more info), or you can start to flower when your plant is 12 - 16 inches (as long as they have shown there sex) and you can expect your plant to double or triple in size during flowering. What is your heigth limitation?
