Just curious: how many T5HO bulbs are you running, and how far above your plants are they? I'm currently struggling with the choice between another pair of T8 shop lights (cheap and available nearby) or a T5HO rig. My shelf that would receive the lights is quite tall and my Nepenthes would be nearly 2' away from the bulbs. I also grow in an enclosed rack so heat is a real issue. T8s seem like the clear choice for every reason except for that little nagging feeling I have that they would provide insufficient light given their distance from the plants.
It's a 2' 2 bulb rack T5 HO. The top shelf is about 18" below the light, the bottom shelf is about 40" below the light.
I divided the heterodoxa x minor a couple weeks ago. It was my first time doing it, so I was really nervous about it. Over the last couple of days, I started to see some signs of new growth on a couple of the little ones!
