Will Broad leaves hygrophyl(Hygrophyla corymbosa "stricta") live in these conditions?
Soil substrate capped with regular fine gravel
Low - medium lighting
No ferts & no CO2
before I was serious about keeping plants, I kept this plant in a tank with way too large gravel and terrible lighting, and silver dollars. The plant lived and had great roots, but never had any leafs (silver dollars)
I would be willing to say that in those conditions you should be fine
