Stack is a powerful natural plant stimulant made from a blend of kelp and other plants extracted with enzymes to leave a full spectrum of vitamins, aminos, hormones and other growth stimulants. Nothing artificial is added and it is 100% organic (cert coming soon). These potent compounds stimulate leaf growth, bud and flower formation, and improve crop uniformity, growth and quality. Stack gives the plant tools to reach its full genetic potential.

When used as a foliar or root drench, Stack may increase micronutrient uptake and correct minor potassium deficiencies.
