An unusual fertilizer?
Some nurses I know are using intravenous hyperalimentation fluid
(diluted) as a fertilizer. This is available from supplies that are regularly discarded in the hospital (bags can't be used for more than a certain number of hours because of the risk of infection).
This fluid contains protein, carbohydrate, even tiny globules of fat, and a slew of vitamins and minerals. They report diluting it, but don't specify how much.
I don't see this as something available except in rather unusual circumstances (hospital nurses with green thumbs). But I'm curious if anyone has heard of this, or a similar substance used
as fertilizer. I plan to try it when I can get organized to set up some similar pairs of plants, one as a control. But what kind of fertilizer would be a good control?
Any comments will be appreciated.
