Has ANYONE in this group performed a careful set of experiments to see if
this stuff REALLY does anything? For example...
At least two pots of the SAME CLONE of a plant must be given a year or so
to become accustomed to their conditions. Then the pots are separated into
two groups---the control group is given normal culture, and the other is
given the superthrive. They must be kept in separate trays. Ideally the
locations of the trays should be rotated each week in case one tray occupies
some better spot in the greenhouse. Then at the end of a year, the plants
can be assessed and the effects of Superthrive evaluated. Ideally, the
person that does this final evaluation should be an experienced CPer, but
not the same one who applied the Superthrive (trying to make this a blind
test). Except for this last step, this is exactly what I did to prove to
myself that a weekly foliar application of Miracid makes tuberous Drosera
very happy.
Has anyone done this? I am still in the camp that thinks Superthrive is
snake-oil (colloquial for semi-mystical nonsense to fool people). I would
like to be convinced.
