yeah ive revegged once years ago.

I had a plant that was well into 12/12 and knocked off a limb of the plant. i freaked out at the time cause i didnt know what to do then stuffed it into  a rockwool cube and tried to clone it in veg.it took forever and grew into  a weird looking bush. the leaf went weird and the plant structure changed once it became large eough i put it back into flower but it didnt really put out anything of quality.

it takes forever to go back to a regular plant once you reveg. its called a monster-cropping and i wouldnt do it again on purpose

it really depends on how far along into 12/12 you are but it will definitely freak out a plant

Sub, your absolutely right, it can take forever. 30 days to start re-veggin and 20-30 days or more, to grow into a sizable plant worthy of 12/12. I agree with you, it could cause probs with the plant, but I've done this many times with no problems. When reveggin fertility has a lot to do with it. You can't push the plant too hard too early, you have to wait until it's well into veg. The more I thought about this, the better tossin them out and starting over was sounding. I hate tossin plants !!! Peace
