New pot - Is it too big?

[Jennyfleur]

Ha ha, Hedge, you beat me to it (so I've just edited that part out!!)

Also, and I can't speak for those who grow S/H, but for other potting media (like bark and s/moss) if you use a pot that is too big for the roots, it won't dry out quick enough and so things like root rot, due to over wetting and lack of air-circulation, become a major problem.
