Iâm still trying to rehab this philo black cardinal, it doesnât look worse but definitely not better. I keep a grow light for 6 hrs a dayâŠshould I increase this? I added some sphagnum moss over the areal roots a few days a go and most daily in hope of increasing humidity. Any other thoughts? When I purchased it had spider mites, but I havenât seen any since being it home.
