Could you mean Hemp??..theres a species of cannabis that is used to make fabric which explains why it's so strong. i think it's c. ruderalis but i may be wrong. so even the other cannabis species carry that trait. kinda by default. but the strength of the plant's tissue is genetic and indicative to cannabis and other crops that are grown for the same fabric making process. sunflowers need to have strong stems to support their height and weight. so my guess is yeah maybe it would work so give it a try. but to think supercropping would work for any plant i think would be a false assumption. that's my best guess. but my advice is to try it anyway and then you'll know for sure.
yeah me too. got it from a store called wonderland. i think i bought it about 20 yrs ago. still in fine shape. wish i was still in as fine shape as the shirt.yup hemp , i got a shirt that i bought 20 years ago still intact with fresh looking colours.
