loligo1964 Posted July 4, 2009 Report Share Posted July 4, 2009 The pellets are as inert as a terracotta pot and do not affect the plants or pH -- but are easily replaceable by pumice or perlite . . . Quote Link to comment Share on other sites More sharing options...

Rob-Rah Posted July 4, 2009 Report Share Posted July 4, 2009 I have had mixed results with seramis (similar). Sarracenia, Dionaea, Drosera seem to hate it - for no real reason I can fathom. Some Nepenthes are thriving with it (N. nothrthiana in a pure mineral soil is doing well), whereas others don't seem to like it. I think it must have something to do with root and root hair structure. Clay - as it dries out - will pull water out of nearby roots as well.

Wasn't that what he was referring to in the first place? LECA is the only material readily available around here, and Seramis is no longer distributed in the UK according to its web site . . .

I have had good results with Nepenthes and Heliamphora with Seramis as a component of a compost in lieu of perlite and pumice, and on its own while establishing cuttings of both genera. I have no experience using it with Dionaea or Drosera . . . Quote Link to comment Share on other sites More sharing options...

My Mexican Pinguicula do well with Seramis as part of their media mix. ...Seramis is no longer distributed in the UK according to its web site . . . I noticed that on Seramis Hydroponics website, I guess they had a niche market here in the UK. At one time it was available in many garden centres but it slowly disappeared from them and eventually got to the point where is was pretty much mail order. I have tried an alternative to it, which is popular with some bonsai growers, and Mexican Pinguicula seem to be ok with it as part of the mix.
