Hi Djay,
The compost is currently under rigorous testing, early indication is showing it to be a brilliant growing medium. The testers are giving positive feedback, saying that it is currently out performing the other brands they are testing against, so we are happy.
We are constantly working on our recipe to get things right. We are aiming for release June time 2009. This of course can be delayed or it could spin the other way and be released early. We are just aiming to get the medium right prior to the release, this way we will be 100% hand on heart that we believe our product to work and be the best on the market.
Our biggest problem currently is the added rockdust. Each 50L back will contain 1.5kg of rockdust, so as you can imagine, the bags tend to be a bit on the heavy side. We have got around this now though

Of course, there used to be a time that peat free mediums would not perform as well as the peat alternative, but with technology evolving and our current ways of thinking urges us all to move on and go as green as we can (no pun intended). Mycorrhiza for instance doe not perform so well in peaty environments, they do however thrive in Loam, which is what our compost contains plenty of

I will keep you all as up to date as I can.
As for the Rockdust. We would like to think it could be available for retail around Easter time. Again, I will keep you all informed
