New research on the effect of selenium on aquaponic lettuce: Effects of selenium on aquaponics lettuce
Anyone else had observations on selenium?
@BrianFlip i actually gave a talk on this at the aquaponics cannabis conference 2020. A great way to biofortify your food/produce with Selenium, iodine, and other trace elements is using foliar applications of diluted or fermented sea water (artificial or natural work). Dilute to 1 ppt or 1g/L then apply every 7-10 days
