What's your recipe? Where do you source your castings? How often do you use worm tea?
I make 5g batches at a time. 2-3 cups of homegrown worm castings, 1/2 cup organic sea kelp and 1/4 cup organic molasses. Brew 24 hours with aeration, dilute 1g to 4 gallons of water and apply once every 6 weeks to my raised beds and container garden.
I have noticed a marked increase in pest resistance, plant vigor and produce taste when used.
