I heartily agree with this, and that's why it's so hard for me to
accept a lot of the reports posted to the list. I've tried
Superthrive and in the long run I haven't found it to be a
spectacular growth enhancer. Nitrozyme does sound interesting,
and I'll probably want to try it, too. While I am encouraged by
Marc's report, I do not feel that a trial population of 4
plants, of different hybrids and species, without a control,
is a valid statistical trial. Using many plants of the same
clone and same age, in the same growing conditions, would be
a better test--half of them with a growth additive, and half
without. Then, repeat the same test for a population of a
different clone. Then another, etc.
That's why it's so hard for a hobbyist to test this stuff. It
takes a lot of room, a lot of attention, and quite a bit of time
to really pull it off.
My guide for growing Nepenthes is to look at the way the long-time
successful growers treat their plants. Visit the collection and
see how the plants look--how healthy they are. If the hobbyist
has kept the plants in very good condition for a long time then
that hobbyist must be doing things correctly.
I'd love to find a way to make the slow-growers grow faster:
rajah, villosa, tentaculata, etc. But no one I know has been
able to get around the slow growth rate using additives. The
plants that achieved any size from seed or TC did it via the
'old fashioned' way--time and proper conditions.
