Just an update. I ordered some Sag. Subulata from a member here since his looked like what I wanted. It arrived a couple days ago and it looks like those in the pictures I posted.
I was interested to see if I ended up with both long, thin ones and the short, thick ones or if the new subulata I ordered would turn long and thin, too.
To my complete surprise and happiness, mine has started shedding its long, thin leaves and grow closer to the substate with thick leaves.
A lot has changed, so I'm not sure exactly what prompted it to change, but:
- Changed 2yr old 55w CF to 55w 9325K bulbs
- Upped CO2 to 30ppm from 19-20ppm
- Started regularly dosing NPK and micros via EI
I'm really happy since, in my opinion, the plants look a lot better now.
