they don't!! it usually full o seeds
When was the last time you bought a "sack" of anything but mexi-brick? I can absolutely without a doubt gaurantee that you have NEVER bought a bag of Nepalese, Moroccan, Afghani, Pakistani, Uzbekistani or any other fani weed. At least a sack of weed that directly came from anywhere other than Mexico. Do you have any idea of just the logistics involved in getting it from over there to here??You try to speak, but only drivel is coming out.
The Mexicans don't give a rats ass whether or not it has seeds, they're selling the shit for $50 a brick. Christ, there's enough lumber in most mexi weed to build a house!!! Judging the entire worlds MJ growing abilities based upon your own meager experience is just plain stupid!!! I have YET to smoke anything BETTER than the Sats my buddies in Guatemala grow. Moroccan pot is fucking great as well, kinda hard to get tho..it's so full of trichomes, they make hash out of most of it. While you're bullshitting, that guy in Guatemala can ID a male at 30 days from seed, and I have never known him to miss. They set aside a plant that they'll seed for the next year, but I have never found a seed in any of their smoke.
I remember when the boys at the Univ of Florida in Gainesville started growing the first Sinsemilla in around '70 give or take.Right about the same time they were doing Maui Waui in Hawaii. The guys in Hawaii and the guys at the U of F got that info from other countries, who have had about 5000 years to practice. We've had what, 250 years, again give or take?? The sheer
arrogance of the American youth never ceases to amaze or amuse me.
To answer the question, they cull the males just like we do. And they don't miss!!!
