Down to Earth Bat Guano 7-3-1 | 10lb - OMRI Listed

Nitrogen-and-Phosphorus Guano for Vegetative and Early Fruiting Stages, 10lb

A plant transitioning from vegetative growth into early fruit and flower development needs both nitrogen and phosphorus at once, a combination many single-nutrient amendments don't cover. Down to Earth Bat Guano 7-3-1 carries meaningful nitrogen, phosphorus, and micronutrient content in one naturally sourced input, flexible enough to mix into potting media, sidedress, or steep into a guano tea.

This 10lb bag suits home gardeners and container growers applying Bat Guano at a scale that doesn't require a bulk quantity.

Key Features & Benefits

• 7-3-1 NPK with micronutrients — covers nitrogen and phosphorus together, plus micronutrients, in one naturally sourced input.
• OMRI Listed — recognized for organic-certified production use.
• Supports the growth-to-fruiting transition — targets vegetative growth and early fruit and flower development in the same feeding.
• Three application methods — can be mixed into potting media, applied as a sidedress, or steeped to make a guano tea.

Who Should Use This

Growers whose plants are moving from vegetative growth into early fruiting or flowering, and who want nitrogen and phosphorus together rather than a single-nutrient input, are the right fit for Bat Guano.

About Down To Earth

Frequently Asked Questions

What growth stage is Bat Guano best suited for?

It's built to support the transition from vegetative growth into early fruit and flower development, where a plant needs both nitrogen and phosphorus at once. That combination sets it apart from a single-nutrient amendment focused on just one stage.

How can Bat Guano be applied?

It can be mixed directly into potting media, applied as a sidedress next to an established plant, or steeped in water to brew a guano tea. Follow current label directions for the rate appropriate to each method.

Is Bat Guano 7-3-1 OMRI Listed?

Yes, this guano carries OMRI Listed recognition for certified organic operations. Match the listing on your package against your certifier's current rules before relying on it for certified acreage.

What makes bat guano different from bird guano products?

Bat guano and seabird guano both derive from naturally deposited animal waste, but they typically differ in nutrient concentration and ratio, with this Bat Guano carrying meaningful nitrogen alongside phosphorus rather than being phosphorus-dominant. Check the specific NPK ratio on any guano product before choosing one for a particular growth stage.
