Terry,

These are 3-5 mm spheroids of highly compressed peat. The pellets are
fairly hard and do not break down even after soaking several months in
water. I expect the main advantage is that lots of air spaces are
created in the media due to the round shape. In practice, we've been
using 50% perlite/50% pellets in the pot, and top-dressing with a thin
layer of pure pellets for aesthetics.

Do you get a stable bi-lobed plant if you propagate one of the traps?
(...I guess I would have heard about it by now if you did :-)).

Pekka,

> What about your tiny little red vft Rick? Was the red part a leaf or root?

My tissue culture red VFT seedlings have all succumbed. I think the
whole plant was red, but it was hard to say as the biggest one only
reached 4 mm. (root + two cotyledons) I think that these plants were
chlorophyll-free, and so they died shortly after germination. All the
green plants did just fine and are now about 2 cm tall after 3 months of
culture. Most of the green plants have bright red root tips.

I do have a leaf cutting of an all-red vft. It has just struck, and the
little plant is 4mm tall. I plan to agressively propagate this plant,
and I'll let you know when I have some to trade.

Pure vermiculite doesn't have enough nutrients to support the cuttings
after the energy in the original leaf is exhausted. Once you get a
strike, you should start spraying with miracid. You could also try pure
peat if you don't keep it too wet. Once the rosette is nicely
established, move it to vermiculite and start a feeding regime. I've
found _P. agnata_ to respond quite vigorously to powdered egg-white.

Shing Lam,

It was good to visit with you on your vacation last week. I hope you
had a good trip back home.

Thanks for the info! I'll try faxing for a quote (after I weigh my
box of Sera pellets and see if these prices are good in comparison).
BTW, what does DATZ stand for?
