I wouldnt bet on getting loads of 'free' bud. I grow my own, and my mate has asked me a few times if 'I want to quick dry some bud and come over'. He might read this, so this is for him - and you...

Im willing to smoke mates up for free, but not all the time. Im the one who has to pay for the electric and tend to the plants each day, keeping pests off them and monitoring pH levels etc. Its bloody hard work I tell ya. And no, I dont really want to keep harvesting them early and quick drying bud because 1. The potency is shite if harvested too early and 2. When you quick dry it, it tastes like shit. No herby, skunky taste at all. When I harvest, and if ive got enough to share (Lowryders dont yield much ya know) Ill tell you. The only plant Im prepared to harvest early is the Lowryder in the garden, and thats only so I can have a smoke for my birthday, and Ill probably get between 4 and 5 grams dry off her. It takes about 70 days for a Lowryder to reach peak potency, so I wanna be able to have enough left for myself to tide me over until the next harvest.

Moral of the story: err... oh yeah, let the grower do his thing, and the rewards will find you...
