i allways come across weed plants, a forest or trail is allways the best place to find them... anyways 1 meter high isnt enough for thc to mature, weed plants can grow up to 8 feet, and usually people chop them at 6 feet, i say you wait till 5 feet to cut them b4 they do.
dont be stupid now, SELL THEM hmm lets see you can usually make a qp(quarter pound off of a 6 foot plant) their are 4 of them...
prices are in canadian:
1 oz.=220$
4 oz's in every qp
qp selles for 600-750$
4 qp's found
================
(lets just say the LEAST you should get is

600x4
2400$
buddy 2400$ you can make, and i hear america costs more for weed and canada is half cheaper around that, so buddy your sitting on some tough ass dough!
if you chop them, hang them on ropes for a week, the thc will drain to the buds, then take the buds off and throw out the stems then sell it...
