NPK Industries NPK Stack - 8 oz

Foliar Supplement for Turnover Stage Feeding - 8 oz

Adding a new product to a feeding program can mean rebuilding your whole routine. NPK Stack is made to work with existing nutrient regimens and feeding programs, so you can add a foliar step without changing what already works. It is applied as a spray at turnover and repeated on a weekly schedule.

The 8 oz bottle suits growers who want to trial a foliar supplement or who run a small to mid-sized indoor space. It is sold as a single unit, so you can add it to an order without committing to bulk quantities.

Key Features & Benefits

• Foliar spray application — applied directly to plant foliage rather than mixed into the reservoir.
• Works with your program — designed for use with all nutrient regimens and feeding programs.
• Defined schedule — the label directions give a clear start point at turnover and a weekly repeat.
• Compact bottle — about 3 in long, 1.8 in wide and 4.2 in tall, so it is easy to store.

Who Should Use NPK Stack

Growers who already follow a set nutrient schedule and want to add a foliar step at turnover. It also suits hobbyists who prefer a small bottle before committing to larger volumes.
