Dark closet?! sounds interesting. here's some information I found. hope it helps you. Rhizomes can be planted in either raised beds or containers and perfer a deep, well-draining soil. Plant bulbs 2" deep in containers and 3-4" deep in open bed. Pot or plant in a well draining media with a pH of 5.5-6.5 and high in organic matter. Successful media generally have 50-65% peat with other components being coarse for drainage. Lime, gypsum and dolomite as calcium sources in the media are recommended for plant health. Incorporation of Terraclor (PCNB) and/or Trichoderma into media helps reduce disease. Water freshly planted rhizomes, then fungicide drench immediately. Maintain slightly moist until substantial sprouts emerge. Keep constantly moist, but not soggy, until peak bloom, then decrease moderately. Becase of the robust nature of the Aethopica potted plant, larger pots or tubs of 10-12" or medium pots of 6-8" are generally used, although some experimentation has been done with smaller, more growth-regulated pots. Greater flowering and growth comes with greater root space. Cluster type bulbs or multiple (2-3), smaller diameter horns 1 1/4" to 1 3/4" will help fill out potted plantings and maximize bloom per pot. Larger horns simply will not fit in the medium or smaller sized pots.
