the trouble with putting up you auctoclave /cooker pot up to 20 psi is that the vessels your using have to be able to handle it , if you dont loosen your lids when stacking in , at 20 psi you could blow up your jars , even de perusing is critical too , allowing min of 9 min at slow release is critical at 15 psi at 20 pis , its extremely critical as jars can explode or implode .if your going to go to 20 psi best you do some very good calculation on your chosen containers . i run my aucto-clave at 17 to 18 psi , with glass jars they do well , softer autoclave plastic dont do so well ,just be aware

Bought a new canning container and plate. Now I can hopefully do 16 baby food containers instead of 4 at a time. Saving in time, distilled water and energy.

I have so many pickles in the basement, I had to stop making more! If you ever visit, you can have some.

Step 2, added agar to jars. The CP ones got activated charcoal 0.5 g/l to tell them apart from the Cacti and Succulents.

I finally plated all 16 bottles. I didn't realize my glass bead sterilizer hadn't reached it's max. temperature of 300C when the 10 minute bleach wash was over so I plated the first two bottles when it hadn't reached the maximum. Those were the only 2 bottles (so far) with mould. Hopefully no more mouldy bottles. It seems that the glass bead sterilizer really helps. The old burning off the alcohol just didn't seem as good. I notice in John Yates set-up he has a blow torch!
So I have 6 containers with Cacti and some Lithops, the other 10 were Sarr varieties, a Nep from Willyck that I cut in half and replated, plus some Dews and VFT seeds. Now to wait. I'll probably order some more weird cacti and do some more dews and VFT's.
