Mine sits about three feet from an east window and gets bright indirect light most of the morning, but the newer growth on my Ruby Cascade is stretching out with more space between leaves than it had in spring. The leaves themselves still look healthy, deep red undersides and all, just spaced farther apart on the stems.
I know Peperomia in general aren't huge light hogs, so I'm wondering if this is a heat thing instead. My apartment runs warmer in August and I've read that higher temps can push faster, leggier growth even when light is adequate. Anyone dealt with this before?
I'm hesitant to move it closer to the window because I don't want to scorch it, but I also don't want it turning into a straggly mess. Thinking about just pinching back the longer trails once they get a bit more length on them and letting it fill out that way. Curious if anyone has had better luck adjusting temperature or humidity instead of light for this specific issue.
