For centuries gardeners have used humic acids to produce greener, healthier plants with more vigor, faster growth rates, and larger yields. Gardeners can supplement their hydroponics or soil nutrient with Liquid Humus to give plants a concentrated dose of essential nutrients, vitamins and trace elements. Liquid Humus promotes the uptake of nutrients by increasing the permeability of plant membranes, improving the buffering capabilities of the medium and chelating iron and other metals. Liquid Humus is also excellent for transplanting and foliar feeding. At a concentration of 15% technical Humic Acids, Technaflora's Liquid Humus is more than twice the strength of other Humate products.
