Growth Science’s Strength is a silica supplement designed to strengthen cell walls. Strength was specially formulated to work with the Growth Science nutrient regimen to reduce stress while providing additional potassium at the early flowering stage to help the plant meet increased nutrient demands.
Why use Strength?

Silica is a necessary element in plants that is often overlooked. Silica strengthens cell walls and gives plants sturdy stalks and stems to support flowering sites; it even creates stronger wider leaves. This results in improved photosynthetic efficiency, more resistance to heat and stress for your plant, and a stronger structure for heavy harvests. Less stress means more optimal plant function, leading to improved yields at harvest.

Directions for use:
Always mix Strength and other silica products into your reservoir first and mix thoroughly before adding any other components. Failure to do so may result in fallout.
Strength is used in the vegetative and transition phase of the plant’s life cycle at the rates below.
Vegetative Phase: 1.25 – 2.5 ml/gallon
Transition Phase: 1.25 ml/gallon
Shake well before use.

Allow for 10 – 25% runoff for best results. Nutrient solution should be kept at 5.7-6.2 for coco and hydro, and 6.0-6.5 for soil.
Feed rates vary by media type. Contact a representative for more details. Depicted feed rates are for drain to waste hydro or Coco Coir set up.
