Thank you I will check the links but as an aside I was thinking of using finely ground Perlite, some coir and sharp sand as starting mix. Topped with a layer of leaf mulch all sterilized in a mini green house for humidity. From my soft succulents disaster due to extreme heat I am thinking of sowing them end of August so that they have six months of cool weather to harden off and get ready for 45c.
Would you agree or disagree with above. Honest comment please and not a diplomatic answer
