Anyone with experience re-vegging ...?

ANYONE WITH EXPERIENCE RE-VEGGING.......i have. Few colones about 7 weeks flowering not doing the greatest and have never re-vegged but am thinking of trying it while starting new plants at the same time so i don't just rely on the re-veg.....all i want to know is it even worth the effort /space/time ?

depends on the space you have. Reveging is fairly easy and there are many guides that will tell you how its done most efficiantly. I assume you are planning to re-veg after you harvest?
If grown in soil ( you don't mention medium you are using ) what I do is to leave the lower 1/3 of the bud sites on the plant and trim all else off. I re- pot, after trimming the root ball by about 1/2 to 2/3. Feed with a 1/2 strength grow nutriant ( it will need the nitrogen ).
Place under 24/7 or 18/6 and in about 2 or 3 weeks you should see new growth where the buds are. The new growth will look a little peculiar, with single leaves, twisting, and other odd looking traits. Don't worry about it, its a normal thing. In about a month or so you should have a healthy ready to take clones or re flower.

good luck

I'm doing it right now and it's pretty easy.

Yea what Randm says. I do it all the time. They take much longer to get going but can be worth it as they get real bushy. And yes, they look strange at first but after some time all normal comes back and they freak out. I even reveg budded stems. Its pretty cool watching the buds grow into monsters from the soil. Good luck!
