hi Owen, hello list,

please let me know what you mean by hydroponically
- do you mean without ANYsoil?
only in a solution of nurients? or do you mean in a substitution of soil,
like rockwool or expanded clay pebbles?
(i'm thinking of the brown ones, not the brick-red ones)

if so, maybe i could help. i'm growing houseplants in those clay pebbles for
more than 15 years now, with more or less success ;-)
as i get hooked on CP's, 1 1/2 year ago now, i started with 2 neps
(unknown hybrids, maybe N. x mixta).
they're still alive & seem to be very happy......
like all others that came later.

i have to admit that i had no luck with the VFT......
but Sarracenias like it very much, too!

i agree....partly!
because please don't forget that "real" soil can be a buffer,
if you're making any mistakes.....
but there's no place for mistakes in an artificial nutrient solution.
And of course soil is just one parameter out of many - means i.e. if you
don't provide enough light, humidity and so on,
you can't expect a wonder.

would be a pleasure for me to help, if i can
- feel free to mail me directly.

kind regards
