I know you're busy Sub, but if you see this I'd appreciate your opinion...As well as anyone else that would like to chime in

My last batch of SS I used 6 bags of Roots, and 2 bags of BioBizz Light-mix. My shop doesn't carry BioBizz soils anymore. (It's cost prohibitive to mail bags of soil from Amsterdam.) It seems as if the Light-mix in SS is mostly for aeration and water retention, correct?
Light-mix is basically perlite, peat moss and sphagnum peat. I was thinking about substituting it with "Botanicare ReadyGro moisture" Which is about 50/50 perlite and coco mixed with trace amounts of humic acid, seaweed meal, and worm castings.
If I can't find Light-Mix would you recommend using 2 bags of the Botanicare stuff, or just go with 8 bags of roots?
Thanks.
