Hi GUNGE..

There is a general rule of thumb in all gardening... NEVER remove more than 1/3 of a plants mass at any one time...

That being said.. you can harvest 95% of the ganja from a flowering plant and then switch the lights back to 18/6 and the plant will re-generate..

You can also clone the SHIT out of a mother.. removing 75% of its mass, and it will be fine..

and NOW you KNOWM
