instead why not get some low cost but decent genetics, maybe only spend as much as 40 bucks on some seeds.
I'd hate to grow from bag seed and do really well and then have the genetics let you down cus it wen't hermie or it wasn't great weed.
My belief is that anyone can grow decent grade weed first time around, just make sure you prepare, read as much as you can and asks as many questions as you can, before you start and while your growing. Theres loads of good guys here that can help you and growing really isn't that difficult its just getting your confidence.
