noob question flower to veg can it be done

i know this is a noob question but can u harvest ur plant and then put it back into veg if so how long before she is healthy enough to flower again

its called re-vegging, and a long ass time, usualy u want to keep a mother or backup plant, but it will work

Do not remove the plant from it's medium exposing roots or it will surely DIE! When flowering cycle is complete, trim all but a few clusters of buds and leaves and then place plant back under and 18 or 24 hour light cycle. Yes it will re-veg but like Pac-man said it will take a long time. Have a Mother plant available or take clones from your vegging plants just before flowering, from the bottom growth of each plant. Trim the rest of the bottom growth to about 6" leaving bare stalk at the bottom. Your plants will resemble Palm Trees. At about 8-10" top your plants to stimualte vigorous top growth and thus flowering sites later...yesca

nice just what i needed to know if my clones dont take before harvest

Do it anyway, just so you know how? This is a re-veg.
It usually takes 2-3 weeks to kick back into veg. Be careful not to over water first month.
