Sin City seeds have very high germination rates in my experience. And thier stuff is very potent. Blue Power, Blue Petrol, Sins Og, Platinum Delights, Raskal Berries. My friends and i haveran a few of the lines. It is some serious fire. Their White Nightmare will blow you the f### out and it gives up the weight big time. She takes 65+ days but the rite phenotype will stay in your garden. Promise. Its that good. Ive heard blue lime pie and sequoia strawberry are giants but how is the quality? I bet ss is just a beast in a greenhouse. Iam definitely throwing w. nightmare in my greenhouse next year. Shes a bad bitch!!
