I grow my kovachiis in very cool temps (min: 55'F / max: 70'F) under 4 LED lights (6500k each). I have them sitting in water all the time.
My kovachii clan:
Awesome haul!
I spoke to Richard who was manning Ten Shin booth and he told me Ten Shin won't be at SEPOS this year!
Regardless, SEPOS is still worth going to whether or not he is attending.
The only show I know is held by the NECPS (Northeast Carnivorous Plant Society). They host a carnivorous plant show every year. Although this year show has past (Sept. 10 - 11).
