I grow Flytraps year-round indoors. I'll say they need alotta light!
A 10 Gal might be kinda stuffy fer em, but could be ok as long as it's not too wet in there.
I grow mine in peat/perlite with some sand in pots in water dishes.
An important thing for indoor growing is keeping them somewhere there's a temp change to cold temps. Like a garage or under an open basement window or sumpthin. Where do you live so I know the temps?
Adjusting the photoperiod to the temps for a simulated seasonal change for dormancy is paramount. I have my season alittle late due to cold temps for spring in NY and warmer temps to mid-fall.
Drosera Rotundifolia & Beleziana's are good companion's... even the low-growing Sarracenia's tend to get too large to make a good companion to Flytraps in a 10er.
Maybe temperate pings or Ultrics? I don't grow those though...
I just water the trays they're in without watering overhead using distilled water from the supermarket.
Outdoors growing is much less time & energy-consuming, and growing Flytraps indoors can be very challenging but also quite rewarding..
Here's an example of some of my indoor-grown plants:
They're flowering now so I'll have some really nice pics up soon.
