Re: Help My Plants Are Gettin Too Big!!!!
Use yarn (NOT string). Gently and loosely tie the yard around the main stalk about 1/3 of the way down from the top. Tie the other end to something low or weight the loose end down with a rock/brick/whatever. Bend down slightly the first day, increase it as often as needed.
You can eventually get it down to a 90 degree angle.
P.S. if your plants have been in flowering for 3 weeks, they aren't gonna grow much taller. The first 3 weeks of flowering is when upward growth occurs. Now the plant's energies go into bud production.
