Home Compost Tea Basics
Brew simple compost tea safely
This guide covers making a small batch of aerobic compost tea: use mature compost, aerate with a pump, brew 12-24 hours, and apply to soil, not leaves, to avoid pathogens.

Start with mature compost
Use finished compost; avoid manure-heavy inputs to reduce pathogen risk.
Aerate continuously
Use an aquarium pump and clean tubing to keep the brew aerobic.
Brew briefly
Steep 12-24 hours, then stop to avoid anaerobic conditions.
Apply to soil
Drench soil near roots; avoid foliar spray to reduce contamination risk.

Comparison
Mitosis vs Meiosis
Mitosis makes matching cells for growth and repair, while meiosis creates sex cells and introduces genetic variation.
