Are there any special considerations for use in a greenhouse or on newly planted seedlings?
Yes. You can stimulate germination and eliminate damping off with an initial spray dilution of 1000:1. Greenhouses that reported a 30% to 85% loss of new plantings due to damping off, report they now have 100% totally productive planting trays. Some nurseries briefly wash new seeds in the solution before planting. This can be maintained until the plants are moved outside.
