Okay, as today is the first nice day, and tomorrow the same, I'm hoping that this works really well and we don't get below freezing any more!. I'm not really ambitious today due to lack of energy (that darned MS, you know?) so here's my system: sifted peat moss (this is damp, as it comes right from the bale): perlite: slag: Portland cement powder, mixed and then water added. One part of each of the above. I'm just making pinch pots for now, due the above reason.
Back with an update...
