Zandor, thanks so much for the info, pond liner, who'd a thunk it?
I'll give it a go.
By the way, I had a little seed growing out the back, its a trance. Now Im in Ireland, so all week the poor thing was frozen, but it really was an experiment. But I brought the little thing in two nights ago, and its soldiering on under the 125w.
I am also getting seeds called Euforia, which are all feminised.
Wonder will these be easier to grow for first timer.

Anyways, thanks a lot for the help, its invaluble.
