I think I will agree with Cobnobuler, I have seen people get multiple harvests from the same plant, it just takes quite a long time to get back into the veg stage. As a matter of fact, and this is for you snkt.
In the book Marijuana Horticulture by Jorge Cervantes, on page 95 he talks about REJUVENATION he wrote " Rejuvenate harvested females by leaving several undeveloped lower branches with foliage on plants. Give her an 18/6 day/night photoperiod. The female will stop flowering and rejuvenate and revert back to vegetative growth stage. Give the harvested, leafy, buddy stubs an increased dose of high-nitrogen fertilizer to promote green, leafy growth. This will help the harvested plant grow more foliage as it reverts back to vegetative growth after four to six weeks. New, green, leafy growth will sprout from the branches and flower tops. Leaves will continue to grow more and more "fingers" as re-vegetation progresses. Let the rejuvenated plants grow until they are the desired size before inducing flowering with a 12 hour photoperiod. If the second crops are allowed to grow too tall, they produce sparse buds. Remember, these plants are already root bound and when given dim light, sparse buds result. Here is a possible scenario to rejuvenate plants. For example, a person who grew a beautiful crop of females and knew each plant by name, had to harvest. Instead of starting from seed again, the grower decided to leave a few leaves and buds on the harvested stubby branches. He induced vegetative growth with 18-hour days and 6 hour nights the day after harvesting. A month later, he took many clones from these original favorite females. The clones were rooted, transplanted, and moved into a flowering room. The original harvest was taken on January 1st. The second harvest was April 1st. The second harvest weighed less, and the buds were smaller. Taking clones from rejuvenated plants also diffuses hormones and severely stresses plants."
I hope this helps you brother, don't let people who degrade you get you down. More often then not, if all they have to say is derogitory they just don't posses the intelligence to say anything helpful. I.E. snkt.
