Reviving harvested marijuana plant indoors

Hi, I'm a first time grower using an indoor cabinet. I was wondering how hard it is to "trick" marijuana into a vegetative state after harvest; or am I better off trying to take clones from a mother plant? I only have one small grow closet so I can only use one set of light cycles at a time.

If it is easy to get plants back into a vegetative state, are there any tricks?
How many leaves should I leave on?
Can I chop the plant down low as it will likely be the tallest I could accomadate by the time I harvest (hopefully)?

Please help. As I am growing some nice but expensive feminized silver haze plants and I don't want to have to buy more seeds after every harvest.

I don't blame you, and I'm doing the same thing. This is in the wrong section, though, this is forum support. I think you want it to be in General Growing. In any event, I've put my first girl under 24/0 fluorescent light. I left just a few leaves. Mr. Fishy knows a LOT about this technique, called re-vegging (re-vegetating?). Just a few leaves he says, so hopefully I've done mine correctly.
