Pinguicula alpina flowering. Contrary to conventional wisdom I carried out a complete soil removal and repot over winter. The plants don't seem to have minded at all.

Hi there!
I have been using mostly Gelrite lately for its transparency and easy detection of potential contamination (my working setup isnt ideal;-).
It is a bit more expensive but you only need about a 1/3 of agar amount and also it is easier to set the pH, which is very important (less impurities).
Good luck! :-)
