Jeff, I have tuberous Drosera, some of which are north-hemispheric,
while others are still latitudinally challenged. Still others are in the
painful process of transition. The northern hemisphere plants are dormant
(except for some stragglers in the peltata pots), while the
latitudinally-differently-abled plants are just emerging from dormancy.
I'm keeping these as cool as possible, and fertilizing weekly. They
should be ok. In any event, I do not recommend you hold
back on watering your tuberous Drosera until they start to die back.
Let them tell you when they want to enter dormancy, as the more time
they are above ground, the bigger and fatter your resulting tubers.

Usually I keep the ballasts out in the open. This gives greater air
circulation. But in my new arrangement I'm enclosing them in a chamber
which will have forced air circulation. Each double-bulb fixture (I use
four bulbs/terrarium) takes a single ballast.

Experiment. I guess it would depend upon the stength of the fan.
