Sorry, sidetracking here...
Neil, I had the same problems as you when it came to pings. Not until I tried this:
The ping came from FEF in the usual dark brown peat medium. *After a while in my terrarium, it started to turn limp. Was desperate to save the plant as it was a gift from my boyfriend so I placed the ping on top of some live sphagnum (dead ones probably will work too but I've not tried) and left the whole thing on the perlite.
With good sun, this plant has produced 4 flowers for me and is now a clump of 4 plants!
It's up to you if you want to use a nicer container but I chose the plastic food container because it cost nothing and it's transparent...I can see water level as well as the perlite (if it breaks down and needs to be replaced). *
I noticed that it reduced root rot and the ping even had roots sticking out in the air. I don't let the water dry out completely but neither do I add water up to the top of the perlite. This method works well for droseras too.
The ping (probably 'sethos'[img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img] that I bought from FEF is doing surprisingly well in its original peat substratum. However, I do not put the specimen in full sun but in partial shade and it is not sitting in a tray of water. If I give it alot of water, the excess simply drains out from the drainage hole from the bottom of the pot. It actually had a small plantlet growing but it died sometime ago. Strange how the same type of plant can survive in rather different environments.
I have some success with growing sundews from seeds because the area that I grow my plant is very windy and this ensures a constant air currect day and night. This, I believe, significantly suppressed the growth of fungus. What you can do is to get the small computer fans and put it near the germination pot to increase air movement. You can also buy solar powered fans kits from the internet. Saves you from paying more for electricity and is also presumably environmentally friendly.
