yea the green jam is "stink" (pungemt skunk IMO), and sells for more than double the price if vincie weed. well yields here differ from wat u plant. if u plant "jam" seeds, u get a shorter plant, somtimes under a foot to under 3' ( pungent skunk IMO ) with yields varying from a 1/4 ounce to 1/4 lbs. (could be more) with good sunlight and
nutes. using vincie seeds u could get 4' to a 9' monster (good sunlight, nutes, animal dung)with yields up to 1-5 lbs. a plant but its a more fruity,citruscy weed sometimes skunky. in terms of growing, jamaican seeds grow faster, i've had a tree using jam seeds grow 4 inches tall and fully matured in 3months, but 2 my knowledge (other peoples
experiences) it's like 3-5 months from seed to pick with jam seeds. with vincie now, 5months the least, to more than 9 months (all times i mention include flowering) of growing from seed to pick. rite now i have two trees both of
which are either some jamaican "grew back" seeds , or one could be from a pure jamaican seed. both of them are under a month (28days) more than 3 weeks but one hatched with 3 round leaves and 3 blade leaves ( i call her
trinity), im going to try and get some pics. also i have a friend who has a tree off jam seeds that's under a foot, 5 weeks old and started flowering 4 days ago, the tree also has a full skunky, non citrus smell. im going to get some pics of that too. good luck on your grow!
