KillerDemo, welcome to Cannabis.com!

I'm a fellow OG refugee as well.

I'm not sure what the best strains are just for yield. I had the best results with Nirvana's Chrystal recently. Nirvana's Northern Lights was second best.

I use Nirvana almost exclusively right now, so I'm unsure of the yields from other breeders. I am (was) a member of the C13 club at OG and I get 4-5 ounces per grow from a Waterfarm hydro system under a 400W HPS.

To agree with some of the other posters in this thread, let me just say this: You really shouldn't sell to anyone under 18. That's bad karma, man. (OG reference-ha!)

Good luck!
