Lynn, I suppose common sense. Aquarium plants and normal plants I know. Succulents I could make out that the top had to be kept dry, bottom I forgot. Tell me one thing though, what difference does it make to succulents if their roots dry out? We dry them on purpose while potting on, while rest of the body parts
. You know, putting them aside for callus formation. Sedums, Semps, Ferns, etc though are a different story due to being cooler climate plants. Like I said, common sense a commodity sorely lacking. I wish it could be bought at the corner store, it would be the hottest selling item.
A bit miffed today.

Arif.
