I'd like some input before I waste money on a plant that won't grow. My low-tech 40 breeder is doing well as I'm finally getting my dosing and lighting all worked out. I currently have a bunch of crypts that are doing well and growing faster than expected. My dwarf lily and tiger lotus are also doing well but not growing that fast. I REALLY want to add a type of hygrophila but my previous experience with hygro did not go well. It generally looked sickly and was growing at a snail-pace. (To be fair I rescaped the tank pretty often it may not have been able to settle in).
The tank is lit with TWO finnex stingrays. Each one puts out ~40watts and based on my research the PAR should be between 40 and 50. Is this enough to grow any type of hygrophila? If its not, would a simple clip-on LED grow light from home depot help? Any input is appreciated.
