I was curious if anyone knows if there is any correlation between anything, ie, lighting, nutrients, co2 levels, and the amount of roots stem plants put out from their nodes. I have noticed that for me, Bacopa puts out roots from almost every node except the top 2 or 3, while my R. indica doesn't do it except in the lower ones where not as much light gets to it. Is it just a difference in species, or are there factors that play into this? Whenever I top/replant my Bacopa I try to trim as many rootlets as possible. I prefer not to see all those white roots streaming down from the stem.
