36G Community, Fine-grade Eco-Complete substrate, EI dry ferts with Seachem Flourish, pressurized CO2 to 30, Dual Bulb T5HO (1 of the 2 bulbs is rosette) (I've been told this is Medium, High, Very High, so really I don't know the subjective strength of it). After almost 3 weeks, some (maybe 25%?) of the planted stems turned brown, but are green in the substrate.
What about you?
