Until Science catches up with us I guess we will never know....I dont know any scientists that will clone a mj plant for 20 yrs and then test it...not yet anyway
I can just tell you from my personal experiences and the people who have smoked and vaped this plant over the years what we think...I know it grows the same way everytime (6 oz yeilds) bud structure is always the same .... the high is the same to my senses and all my friends
during a 20 yr period... you would think if there was a degordation to this plant it would show itself in either the growth pattern or the potency
I have been cloning my ECSD, Chem4, 98Bubba, for 6 yrs now......everything I grow is cloned...dont want to loose a top strain.
I have a few friends who have grown bonzi marijuana plants they keep moms alive for 10-15 yrs....they pull starts off the plant once a month
Seeds dont give you the same product twice.....if you dont clone you loose that individual plants heritage of the mom and dad.
Seeds to me are christmas presents... every seed is different and you dont know what your getting until its opened up,dried & tried
All the people I deal with order seeds... pop all of them... clone all them....find the best 1 out of the bunch and keep that 1 going in clone form...
why keep paying 100s of $$ for seeds to the same strain of weed ??? you can buy a few packs find the best one and keep it going
