I use Debco but usually mix it half and half with my mix. Course sand, el cheapo potting mix and coir. I am trying coir out with a lot of my plants now. Especially my fat-plants.

I just wish I could get hold of some small scoria to put in my mix, can only get the bigger stuff here.

I got lithop seeds from Vlado a few years ago and swore I would never go back for any more seeds. So interesting to hear how everyone is going with his seeds now.

HAHA - Pumice - Go to Taupo in the North Island of NZ - the Desert Road - not a normal desert - instead of sand it's all pumice and ash - very good for the soil

With scoria - if you have the ability heat it up first (BBQ is a good idea) as it's full of air pockets - let it cool slightly (or throw them in water) and they'll break up into even smaller pieces.

Pumice - I am sure you can get bags of the stuff in Bunnings.

I used scoria (aussie stuff) once in a Hangi I had here - and the whole lot exploded sending shards of hot scoria flying around the house!

i love taupo, we used to go there everytime we went over to nz. Lol at hot scoria flying round your house

Pumice - what's that ????........................ if only Bunnings stocked here in sunny Mildura they never have anything I want, probably think its too far out in the sticks for anyone to want it hehe

Pumice - It's a very light volcanic rock that actually floats on water!!!

I am positive you can buy pumice at health shops too - you use it to rub off callouses I think (haha).

Yep I have that one good for the heels in summer (lol) but its just impossible to buy the chunky bits for my soil mix where I live

aren't some brands of cat litter just ceramic/stoney bits? I seem to remember it been used in homemade mixes. I will try and findout where I got this info from.,

I have heard about cat litter, but wouldn't it hold moisture????
