I have now and have mailed out hundreds of the "old" seeds collected by a friend (RIP) who sold tons of Mexican weed until about 8 years ago. He would collect and give me his best bagweed seeds from the kilos of Mex weed he bought. We're talking South Texas, fresh across the border.
It never failed forum buds would beg for them and then most would forget them, or lose them, in favor of "designer" genes, something with a name. Gotta have a frickin' name ya know. I pretty much stopped offering those seeds. I must have given a Florida noob a thousand of those old seeds and never saw a plant posted. I gave some old Mex and Zamal (African lineage from La Reunion) to a veteran grower years ago. He did real well with the plants outdoors, they grew huge and he just loved the way those plants grew, then somebody swiped the stuff. I still have some of the great sativas - old Mex, Zamal, Dalat Vietnamese, O. Haze from The Flying Dutchmen and Bros Grimm In/Out mix, the latter having some indica in it. As far as I know I'm the only one that still has some of Sly and Soul's original stock, stock that was used to create their Princess/C99 line. My 4 cola topping plant on page one is such an example. Cost me a buck a bean from a now defunct seedbank, the largest and one of the first out of Canada called Heaven's Stairway. I got 20 of them.
I'll try to get you in Cooter@666. That's where most of the veteran growers from RIU hang out.
