How to Use:

Brewing with air:

• Add tablespoon (5g) per 5L of unchlorinated water

• Place the tea in a mesh bag and bubble with an aquarium pump

• Brew for 24 hours in warm weather, 36 hours in cooler weather

• Ideal air pump power: at least 3 watts per 5L of water

• Clean brewer and air stones thoroughly after each use

Shake brew method (no brewer):

• Use 1 teaspoon of High Tea in 2L of dechlorinated water

• Place in a food-grade plastic bottle

• Shake vigorously and often, burp the cap to introduce oxygen

• Do not use if it smells bad (anaerobic). A good brew smells sweet/earthy

Dilution and Application:

• Soil Drench: Dilute brewed tea 1:5 with unchlorinated water

• Foliar Spray: Dilute brewed tea 1:10, strain through a fine mesh

• Apply every 2 weeks for general support

• For stressed or fast-growing plants, apply weekly if brew quality is maintained

Water Quality:

• Always use unchlorinated water (let tap water sit 24 hours, or use rainwater/RO)

• Chlorine or chloramine harms microbes; avoid it in both brewing and dilution

Storage and Shelf Life:

• Use brewed tea immediately or within hours of completion

• Avoid storing brewed tea longer than 2448 hours
