Grow

If you know your crop and you want the dial in your hand, this is the series. Grow, Micro and Bloom let you move ratios week to week instead of accepting someone else’s curve.

Grow is the potash-and-nitrogen end of that system — the bottle you lean on hardest through vegetative growth, and the one you pull back as flowering takes over.

Guaranteed analysis — 2-1-6

• Total nitrogen 2.0% (0.5% ammoniacal, 1.5% nitrate)
• Available phosphate 1.0% · Soluble potash 6.0%
• Magnesium 0.2% water-soluble · Sulfur 0.5% combined
• Derived from potassium sulfate, monopotassium phosphate, potassium nitrate, monoammonium phosphate, magnesium nitrate, ammonium nitrate, ammonium sulfate, magnesium sulfate

How to run it

• Balance your water’s pH first, then Micro goes in first — Grow and Bloom follow in any order, supplements one at a time after that. Stir thoroughly before feeding.
• Store out of direct sunlight and above 48 °F (8.8 °C) to prevent crystallisation.
• Replaces any 3-part base nutrient.

In the bottle: green, consistency of water, faint ocean smell. Shelf life 3 years or more.
