Yes, it will work once or twice. Just when you harvest MAKE SURE you leave some fan leaves on and tiny popcorn pieces if you can.. The more green left the quicker it will turn around. Be aware though, re-vegging can take over a month. In my opinion it's much better/faster to just take a clipping off the plant and root it before you harvest.. Start over new, will grow faster too.
good luck
Thanks so much for your reply, and help!
Okay so, another question - after I harvest, should I go back to 12/12 lights immediately? Also, what about the nutrients? Do I do water for a week or two, and then switch back to 2 week nutes?
I'm already using Super Thrive in my mister, and reservoir, but is there a more concentrated method I should look into to help them survive..? I would have taken more clones, and have a few from my current batch, but was placed into an unexpected situation and now need more, as soon as possible.
