To continue to fuel the debate, I wanted to post an update showing my SD Kronos that I have been growing indoors for 2.5 years under artificial lights (high PAR LED). A year ago I went on vacation for 2 weeks and screwed up my watering system, so the plant had considerable die back. I lost about half the total biomass, but the plant has bounced back after a year of proper care.
I had to transplant into a 12.5 inch diameter pot because of over crowding. The plant has so many mouths to feed that I could feed it every day and still have unfed, open mouths wanting to be fed.
My experiment shows that dormancy is not required. My experiment also shows that venus fly traps geow VERY well indoors. The most important thing for indoor growing is to have a PAR meter to ensure your plant is getting enough photosynthetically active radiation. Also, indoor growing, of course, requires feeding. I use blood worms. This causes the plant to grow more vigorously than it would in the wild and it creates new divisions, which take about 6 months to reach adulthood under my set up. Much faster than the conventional wisdom shared in this community.
The fact that the old divisions may die after a couple of years with no dormancy is a non-issue because the original mother plant is technically a meristem that has been proven to die after flowering. So what people think is the original mother division is technically a clone of the mother meristem after flowering, just like new divisions are clones of the mother division. In my frow set up, so many new divisions get created all the time, and there are always energetic young plants that have only been alive for a year. Some divisions flower. Some divisions are small. Some divisions are giants.
Attached are two pictures. The original plant in its 3 inch diameter cup 2.5 years ago, and the plant now in a 12.5 inch pot.
Growth is so rapid that I may need to transplant a second time this year! Oh and notice the live sphagnum? It grew on its own from the dry Besgrow spagmoss brand sphagnum.
Back to my original point: dormancy is NOT required to grow a thriving venus fly trap. But hey, maybe the dogmatic types here will be right and in 6 months I will have to downgrade from this 12.5 inch diameter pot back to the 3 inch diameter cup the plant started in. I am confident that in 6 months they will move the goal posts again.
Dogma never landed a man on the moon.
