Stack is a natural plant nutrient made from kelp extract. The nutrients in Stack encourage healthy growth and flowering. Stack gives the plant tools to reach its full genetic potential. When used as a foliar or root drench, Stack helps correct minor potassium deficiencies.

Instructions for use
May be used as a foliar spray or root drench, one application weekly. Safe for use in irrigation systems. Stack contains organic ingredients and may separate in storage. Shake well before use.
Apply Stack from the final week of vegetative growth to week 4-5 of flowering, or once plants stop growing vertically.
Mix 1-2ml per gallon of water in a weekly mix. May be mixed with a regular fertilizer recipe. Add last to the reservoir.
Mix 7ml per gallon water and spray thoroughly once weekly. Spray with lights off and allow to dry before turning on. Do not spray past week 3 flower.
Mix 2ml per gallon water and bare-root soak for 30-60 seconds before transplanting or water in solution after transplanting. Stack may reduce transplant stress and improve plant vigour.
Mix 4ml per gallon water and soak seed for 1-2 minutes before planting. Stack may increase germination rates and plant vigour.
