I can only go by my own experience of Drosera peltata, which has so
far proved easy to grow from seed and flower. During the (Winter)
growing season, mine stand in a water tray in a cool greenhouse (down
to 45F / 8C). They get sun for part of the day (if the sun shines at
all of course!). I've also kept some on a windowsill in the house
when the greenhouse is full. I don't suppose a tall Drosera like this
would appreciate dry centrally heated air-conditioned air, but the
water tray should go a long way to helping it. My pots have never
been deeper than 4-5 inches (10-12cm).
A couple of weeks ago, I tipped out a pot of dormant 1 year-old
D. peltata seedlings (there were lots in the pot). Although I could
see lots of small tubers (only 1-2mm) I felt it safer to use all the
old soil in their new pots (mixed with new of course) so as not
to lose any tubers. I divided them up into 12 new pots. Some of
the tubers were already developing underground shoots, and some were
inevitably damaged, but where these snapped of shoots were left
protruding from the soil, I can already see them sprouting leaves
from lower down. I've also resumed watering my older D. peltata pots,
but they haven't emerged yet. The tubers do tend to form near the
bottom of the pots, and maybe they would like deeper pots, but it
doesn't really seem to matter.
