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, Stack helps correct minor potassium deficiencies.
Instructions for use:
May be used as a foliar spray, one application weekly. Safe for use in irrigation systems. Stack contains organic ingredients and may separate in storage. Shake well before use.
Application Timing:
Apply Stack from the final week of vegetative growth to week 4-5 of flowering, or once plants stop growing vertically.
Foliar Spray:
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.
Transplant Use:
Mix 2ml per gallon water and bare root soak for 30-60 seconds prior to transplanting or water in solution after transplanting. Stack may reduce transplant stress and improves plant vigor.
Seed Treatment:
Mix 4ml per gallon water and soak seed for 1-2 minutes before planting. Stack may increase germination rates and plant vigor.
