Hi Steve;
the Actwin APD list kicked me off for some reason.

I agree that the dormant period is stating to look like some sort
of myth and that these plants ans other Aponogetons require
very heavy feedings; a plant-tab a month near the roots is
not to much.

As for temperature I have found that lwer is better than higher
but that they do not suffer up to 82F, but they do INO grow
better at cooler temperatures (62-75).

Jim Robinson has had far better luck with these things than
I have. Back when he was importing them he had maybe 50 i
a 65 gallon tank and when he sold maybe all but 12 those
plants spat out seeds and baby plants with wild abandon.
