Why not go Seedsman, you can get about 10 seeds feminized for near the same price, give or take alittle. They seem to have a pretty good rep as well. Just my 2 cents.
Are Flying Dutchman or White Label not worth the extra cash? Also, I figured I could throw down the extra money, for better potency or whatever, and I would get a free Northern Lights seed.
BTW, if it interests you, I'm only buying two strains, the White Widow and Afghan Kush both feminized. But with Attitude, I'll also get 1 Durban Poison (fem), 5 Power Skunk, and 1 Northern Lights (fem) seed free. So it help w/ the variety. Also, I'm not really planning that big of a grow.
