drive out to the country, walk somewhere secluded, and put the plants you dont want outside. go back in a couple of months and see if they are still there?
i would clone the plants you have 15-20 times. see how many you can get to root. then grow all of them out to support the number of clones you need to fill the volks. by the time you are ready to do the big clone, it will be end of october. get the volks and clone the hundred clones. flower those and some of the moms by supplemental light, keep a couple in veg to clone again a week or so before four first run finishes.
this will take you to christmas untill you have anything to smoke, but it will get you an the fast track to be pulling over a lb. easy every two months.
OR
clone a bunch from the bottom branches of what you have, and in a week or so, flower what you have and veg the clones. then you have smoke by thanksgiving and will be ready for the volks, which could be done by new years.
you dont need much more. the volks, light (ballast, bulb, socket and holder), res, cloning stuff, and 80 3" RW cubes. could be done for $1400 if you order online to make it cheaper.
