Hi, folks,

Thanks to the generousity of Jos Franken, I was able to set up a
small germination trial using N. madagascariensis seed in some of
our controlled-environment incubators.

I didn't want to blow all my precious Nep seed in the cause of
science, so the trial was very small-scale ie. not statistically
significant, but the results may be of interest.

The full story can be found at

For those of you who haven't got the time to look, here's a

Gibberellic acid has a major effect on germination - faster and
higher percentage.

A constant 31C gave better results than a regime of 26C day/16C

So there you go - no big surprises, but nice to show it in a quasi-
scientific way! And I'm having surprising success weaning Nep
seedlings off agar into compost, so I should have plants up for
grabs next year.

Good growing (and germinating),
