How do i stop it growing

My plant is approximately 16Inches high and i want it to stop growing it is under two 100 watt CFLs
and it keeps hitting the light and burning the leaves i need it to stop growing.

I also considered replacing the 100 watt cfls to a lower wattage so if it hits the light it wont burn but then the buds might not be as potent

Is there anything to do to stop it from growing it is in its 12/12 cycle

tie down the stem (slowly - you dont want to snap it) and each day increase the tension... ive managed to make mine go into a spiral which is pretty cool since any vertical growth just causes it to expand sideways if you see what i mean. You could go for an S shape which would do the same thing. good luck mate

What i did when i had the same problem was.. I took the main cola's and i bent them slightly away slowely and tied them down with some zip-ties. the Repeat if needed.
