    I use this product for the vegetative growth stage on half of my plants and they ended up going nearly twice is tall and lustrous than the other plans I didn’t fertilize and shipping was quick! I got it 3 days after I ordered… fantastic product overall! 😉

    Low cost, no ammonia lockout. I use it at a much heaver rate. once or twice a month mix it at a rate of 1 tablespoon per gallon of water with the same of Epsom salts. Soil drench or foliar spray at this ratio. I swear it will not burn your plants at this amount and kicks growth rate into hyper drive. Foliar spray orchids with this same mix for a rapid emerald green color if the leaves are starting to yellow.

    Great for assisting the decomposition of stumps. It is also an excellent economical ingredient in the making of Black Powder in small amounts.
