brilliant!of course, why wouldn't you be able to? you could probably do it in socks if you new what you were doing.
I am hatching my new lil babies right now. Once we have picked one out cloned her to hell and back, i am going to try and grow one out in a tube sock! Just for something to do. lol I'll post pix, as soon as it starts.
True SOG's are most effective with clones, seed grown plants tend to have varied growth rates and will not produce the same yield in a SOG as clones. You can use grow bags or anything really but if you are talking about an entire life cycle seedling, veg, flower then SOG just is not very effective.
