Questions and answers

Is Microbe Life All In One safe for aquaponics?
The label lists aquaponics as a use, and the 0.5-0.5-0.5 NPK is low enough for most systems. Start at a reduced dose and watch fish and plants for a week.
Is it OMRI certified for organic growing?
No. It is labeled organic based but not OMRI certified, so it does not qualify for certified organic production.
How much does a gallon cover?
The label caps use at 50 concentrated gallons per half-acre per year. At typical dilution a gallon goes a long way in small gardens.
Can I use it in coco coir?
Yes, coco coir is a listed soil type. Coco holds little nutrients, so pair it with a calmag or micronutrient source if plants show deficiencies.
Is $14.99 a good price?
It is the best new price among the 3 stores listing it as of November 6, 2026. Compare against the other two stores before buying multiples.
Do I still need other nutrients with it?
For light feeders, no. Heavy feeders like tomatoes and flowering crops will likely need a stronger bloom or nitrogen feed alongside it.
Where is the Microbe Life All In One cheapest?
