Sure, but they would have to contact you. They're not in the business of just giving away seeds. If you're on a tight budget, check out MSNL. They have some really cheap seeds (non fem) with good genetics.
Ask around locally if you don't want to buy any online. Someone locally should have a free bag seed or two to try out. If you are serious about giving it a shot, i have had really good service from herbies and green point seeds.
