Hi David,

Did anyone respond to your question re growing under lights. I don't
remember seeing anything. I am a beginner with Arisaemas and a
compulsive seedaholic. I have for several years been trying to get
Arisaemas to flowering size by growing under lights and have often tried
to get an extra growing season in the year by storing tubers in the
fridge for 2-3 months and then bringing into growth again under lights.
My set up consists of a few shelves with 2, 4 foot fluorescent light
fixtures each with one warm light and one cool light tube. This seems to
work quite well. I have them on a timer to give at least 12-14 hours
light per day and keep the lights on chains so I can move them up as the
plants grow. I now have some of the older tubers planted out and wait to
see what kind of success I will have.
Hope this helps
Roslyn Duffus
