Is my sarrencia growing normal?

Got this online and bringing it out of dormacy. First tube just wanted to make sure it was growing right, but it doesn't appear to have an opening at the top.

I have a 3' 39 watt bulb across my whole shelf and a sansi 5w within 8" of them and his neighbor. Substrate is sand and perlite(carnivorous plant mix from carnivore nursery website).
