I grew mostly nothing but Mex swag seeds for about 6-7 years outdoors.... Since weed is so cheap here in south tex, I'd just keep seeds from whenever I'd run into a dope sack of bud, and would mark them all as how I rated the smoke from 1-10 of the original pot, and moreless named them by how I thought it would taste/look or the high.... I've grown plenty of Mex "crap" weed seeds that has been just as good as strains I pay 50+ dollars for 5-10 seeds, and if the mex weed I would get was good, I could get 10 seeds off a Nick..($5 and normally about 3.5 grams now a days, but 5-10 years ago I could get good mex weed for a dollar a gram, and sometimes less..... great mex bud have very few seeds, and maybe could find 5-10 in 5 grams, and all seeds are fully mature.... I still keep seeds, and gifted seeds from friends who run into good stuff, and save them for me...... So I say you sure should try out growing those seeds... Never know if you'll run into a gem.... They will normally grow 2-3x as good as the original, plus you know exactly what you put in it......
1 thing I did find out about alot of mex seeds, is that alot have issues with being grown indoors, and I find that the foilage grows very thin and bland compared to bought A+ genetics....Most are indica dominate, but you do run into alot of huge sativas.....I've grown alot alot of great mex bud that has turned out DANK!.... But then again, being from south tex, the word in the street is that all the great brick weed stays down here, and the Dirt dirt junk is smuggled up north, since they know it will sell regardless, and people here wouldnt pay more than 100 for an LB of dirt, cuz weed like that here wont get bought cuz there is so much of it, and there is always someone with better stuff... Up north "they" can easily get 5-600 LB for the same dirt..... When I do get something like that, I deseed it, and make butter.... Quality mex will go for about 225 an LB to 300/350 if it is BOMB, and close to homegrown.... the kind that you can actually see crystals, and find 20-30 seeds at most in a whole lb if you're lucky..... Those are rare, and I'd buy it up in a heartbeat since I know I can easily make my money back, and still have an 1/2 an LB to myself, plus seeds of some REAL DOPE weed... But again... These are rare, so best I have seen in a while is 225 bud
