Thats pretty genrous, hell I'd jump in on that deal. That is 2 1/4 lbs for you and he'll realize another 5 lbs for himself, for $200 thats pretty damn good all the way around. A guy here offered me a gurantee of 2 lbs but it would cost me $2,000 to join. If he's a good grower he can probably get that yeild. If it all sounds legit I'd jump all over it but see if he has any references.
