Well I decided on the green kind because when I was looking through the seed catalog, there was regular white, a brown kind, and " Erlene's Green" and though I wanted all 3, I could only afford one and the green was just too interesting and cool to pass up. I never even heard of arctic cotton. I guess you will just have to trade for that fiber if the arctic one isn't useful, huh? I live in Texas so I could grow nothing but cotton if I wanted to. I only have 10 plants this year but next year I will have a lot more seed from these plants and can grow a bunch. I'll see if I can send you a little bit after harvest just for kicks.
