Kaleidoscope II Brother Mendel

So I’m noticing the mix of Coast of Maine I have with Commonwealth Canna tends to stay pretty wet. I’m reducing my watering to 350-400ml every 3-4 days. I think I’m going to try a coco coir perlite next time with earthworm castings and organic amendment/ ferts. Otherwise the girls are getting roughly 40DLI with the PPFD about 500 per plant. They seem to be responding well.
