The main problem growing cacti is not the growing medium but the pH of the water. Where possible use rainwater and adjust the pH to 5.5 - 6.0 for optimal nutrient uptake and growth. I use pure pumice or Lava Rock. The only pest that I get are mealy bugs which are easily dealt with by the use of 70% ...

Thank's for everyones input. :notwo: So I'll start from here then and see how it develops. I wonder if it might grow into something more like the field number data base that started out as a couple of pages of A4 how many pages are the now Ralph? It will be interesting to see how the online journals...

Cheers Ralph I am not sure what you mean by a "one stop post".
I have an update with three more journals listed so I'll wait from you before posting it.
Hope you missed the storms.

Thank's for them Ralph.

As some of you might already know there are a few free online journals to do with our hobby. So I have put the journals that I know of the links and volumes/issues available to date. If you know of any that I have not mentioned please let me know vie reply, E-mail or FB message. John.gamesby@ntlworl...

Yes as it says in the topic bar it is Dudleya verityi.
It tends to grow in the small cracks and pockets in the rocks in the moss. In very dry conditions it can pull itself right into the moss.

Ernie ISI1641 is a 1986 introduction. X Cremnoseedum ‘Crocodile’ Mr & Mrs Robert Grim of San Jose, California made this hybrid along with many more. This one is Cremnophylanutans and Sedum furfuraceum.

Hope this helps.

Lets hope DNA studies are done first this time to prove relationships or possible hybridity before the morphologists try and classify or reclassify it on visual characteristics alone, as they did with Digitostigma. . Was that really done with Digitostigma? What was discovered? I'm sure that it was ...
