I just trimmed it this morning and I am seeing new runners daily. Looking forward to this taking over. My glosso has been acting strange lately - it once grew horizontally but I left for a week and the top of my tank was blocked out by floaters resulting in all of the plants growing vertically reaching for the light. That was 2 months ago. Trimming and trimming still results in vertical glosso growth with only a few being trained to crawl.
5 inches isn't too bad. I do have pressurized co2 and the plant pearls at the end of the day. I'm getting in some gelatin capsules today so I can make some osmocote root tabs. I'll pop a few underneath the soil where the hairgrass is.
I appreciate the advice Veritas...I'll upload a photo in a week once the new growth comes in - hopefully it still looks like E. parvula
