So I purchased some Nepenthes seeds to try growing Neps from seed and decided it would be a nice experiment to compare two of the growing guides listed on this forum.
I purchased N. attenboroughii, N. naga and N. maxima "wavy leaf". All of them were collected in the wild and (according to the vendor) every batch came from a single plant.
I tried the method of just sowing the seeds and putting them under strong lights, and the method of covering them completely for 10 days and then putting them in less strong light.
I divided the seeds randomly over two pots, with every pot containing half of the seeds from 1 species (not very good statistically I know but I don't want to spend a lot of money on 30 repeats).
this is how they looked after being sown on 19/06/2013 (I only photographed one pot for every species)
Nepenthes maxima "wavy leaf"
First germination was in the N. attenboroughii pot under the strong lights on 16/07/2013, followed by germination of N. attenboroughii in the other treatment on 18/07/2013.
By now most of the attenboroughii seeds have germinated but none of the other seeds have shown any sign of germination. Do these species require other specific conditions than the attenboroughii?
In any case, for the attenboroughii the treatment does not seem to matter as 3 days difference is very small (and probably more due to me not seeing the germination).
