Guanokalong Powder — Organic Phosphorus Fertiliser for Root Development and Flowering
Best for: Organic growers wanting to boost root structure and flowering without synthetic chemicals
Our thoughts
This is proper bat guano — 100% natural, no fillers, and it does something most synthetic nutrients can't: it actually builds microbial life in your soil while feeding your plants. The phosphorus-rich NPK 1-10-1 hits the sweet spot for flowering and root development. One a lot of organic-minded growers swear by.
Guanokalong Powder is a 100% natural bat guano fertiliser designed for growers who want organic inputs without compromise. With an NPK of 1-10-1, it's loaded with phosphorus to stimulate root growth and flowering, plus microbes and enzymes that build long-term soil health. Mix it into your compost, top-dress it, or brew it as a tea — it works from week one and won't scorch your plants.
How it compares
Bat guano sits in the organic phosphorus category, but not all guano is the same.
-
vs high-nitrogen bat guano: Guanokalong's 1-10-1 focuses on flowering and roots, not vegetative bulk
-
vs bone meal: Faster acting, microbial activation included, works from week one rather than weeks in
-
vs seabird guano: Better balanced trace elements, less risk of nutrient lockout
The key advantage: natural slow-release means zero burn risk at standard rates, and you're feeding your soil biology at the same time.
Usage guidance
Mixed into compost (week 1)
Blend 1kg Guanokalong with 100–200 litres of compost, or use one 50g measuring cup per 7-litre pot. Effective from week 1 through week 12.
Top-dressing
Apply 100g per plant as a dry top-dress, then water in. Works well mid-cycle when you want a phosphorus push without disrupting your root zone.
Guano tea (liquid extract)
Mix 1kg powder with 10 litres of water, stir weekly for a month, then use as a liquid feed in the same proportions as the powder. Good for fast nutrient uptake without handling.
Reusing soil
Add 400g per 50 litres of spent soil or coco to rebuild microbial life and nutrient reserves for the next cycle.

Who this is for
- Organic soil growers building long-term soil health
- Growers who want to avoid synthetic phosphate inputs
- Anyone running indoor or outdoor mixed cropping
- Experienced growers who understand crop-specific nutrition
- Soil recyclers wanting to restore microbial life between cycles
Works well indoors and outdoors, though soil growers tend to report the best flavour and aroma results.
Our take
Guanokalong Powder is organic fertiliser done properly — no marketing fluff, just bat guano that's been handled right and won't burn your plants. The phosphorus content hits hard when you need it, and the microbial activation is a genuine bonus for long-term soil structure.
If you're serious about organic growing and don't mind working with powder, worth picking up while stock lasts. Does exactly what it should, and growers keep coming back for it.
