Any hints for growing emersed?
I tried it using DSM in two batches. The first was misted with water from my EI tank (7.8 pH, 8 GH) and soon went to a dark brown. The second batch did better after I cut the tank water with distilled at a 1:1 ratio.
This suggests the plant does better under softer parameters but other factors can't be ruled out for the first batch apparently dying off.
