Mary Sue: Sure does raise the adrenaline level. I grow a number of tender bulbs as you all have seen from the images posted on the Wiki Wiki. I have a four by three foot stainless steel trough with a five inch side that sits under a HID light. I have three inches of gravel in the trough, I have never changed the duration of light and dark that the plants receive and they seem to flower on schedule as if they were outside. I do water based on a schedule that approaches the normal water availability in the native environment. Feed most bulbs with a 50% african violet plant food. Those that are summer growers are placed outside for the summer starting in the shade and gradually moving into full sun. This has worked very well with boophone disticha and eucomis sp. after some good advise from Ken in SF. Arnold New Jersey
