Hey there Luminous! I can't speak to the Red Poison as I have not grown any out yet. From the pics in other peoples grows, the color doesn't seem to be that consistant. On the Dark Devil side of things, I have some going right now and they are some of the tallest I have seen. It seems to be a picky strain though, because others have grown and shown them to be much smaller than mine. The potential is there, but time will tell.
