Leo,
Thanks so much for the info!! So far spider mites have stayed at bay, but
it is early. I'll start a misting program. I got a glass shield for the
HID light so that flying glass would not be a problem...for once I planned
ahead. I allow my Brugmansia to go completely dormant for the winter as it
is easier then allowing them to grow.
Thanks also to Dean Cook for his earlier advice on the grow lights.
I'll let any other northern growers know how it went in a few months when
everybody should be dormant.
Dan

had maybe 40 pots full decide to not break dormancy this year until August
and so my usual plan of attack was out of the question. Thus, I now have
quite a few under a 400W MH HID grow light and after 3 weeks they are doing
wonderfully, except for the aphids which have already proven to be a pain in
the backside! I was wondering if anyone could provide any additional
thoughts on care as we move further into the fall/winter. These are sitting
on a table, not on the floor and so I think there will likely be enough heat
for them (no cold basement floor). I also have 2 separate fans continuously
blowing to keep excellent air circulation. I have not bothered to mist them

I can not be the only one growing Amorphophallus through the winter under
lights and so I would truly appreciate the thoughts of the long-term growers
on this forum. Thanks in advance for any help you can provide,
