No, don't make that assumption. My growing conditions are most likely very different from yours. All my plants are in 2-4 inch pots and majority are in morning sun. So that alone would account for some differences in coloring. Only the big pots of Noids on the other side of the townhouse are in afternoon sun. I didn't feed my plants (except for the sandy loam in the plant mix) for 4 years and just started this year with organic matter feeding. The lack of regular feeding would affect the size of the potted semps. Don't get me started on different sizes of pots...
