Excellent write up, and the blog link was also fantastic! Bravo.
Chink 9, I find it best to rotate my plants. Especially pothos. I have some that hang in the window a few weeks, those get swapped out with the ones being nibbled and stepped on now. Your fluorescent light is probably not sufficient wattage for the plant to really thrive. I find they grow best hanging in a window inside. Full sun outdoors can cook them fast, at least where I live. Water them twice a week hanging in a window, and you can swap them out before they even look much worse for the wear.
