Hi there. I grow my crypts both outdoors and indoors. I grow both in organic rich soil with some moss above it or pebbles. The ones indoors are in plastic containers in individual pots with 50W LED lamp, no misting but are covered with plastic with humidites from 80-95%. They pretty much grow a leaf per week. The outdoor crypts are in shallow basins with indirect sometimes direct morning or afternoon sun no shading or humidty domes but maintained humidity of 65-72% and only mist if Ca and Mg is needed. Hopes this help.
