yes you can put them back on a 16 or 24 hour light schedule and they will go back into veg. Supposedly this is supposed to keep the plant from reaching peak potentail but ive done it many times and there is no difference betwqeen revegging and just continuing flowering in my opinion.
the plants grew just like normal after that, didnt hermie (out of all 25 i did it with not a single herm) and the buds were no less potent than the ones that were flowered out like normal.
i think the rumor about it possibly making the bud weaker is b/s because ive seen it differently.
