16 organic ingredients, one bag, one monthly top-dress. Then just water.
Gaia Green All Purpose 4-4-4 is a dry amendment that replaces a shelf full of bottles and a feeding schedule. It's a balanced blend of bone meal, blood meal, kelp, glacial rock dust, greensand, and 11 more ingredients that break down at different speeds, so plants get nutrition immediately and steadily over weeks. Organic growers across North America have used this exact formula for over 20 years in gardens, containers, and indoor setups.
- Measure and mix multiple bottles every single watering
- pH pen required, adjust every feed to stay in range
- Salt buildup over time, flush protocol needed before harvest
- Starter kits run $30+ for a 3-part system, plus supplements
- Overfeeding burns roots fast with no buffer
- Soil biology largely ignored, nutrients fed directly to plant
- Top-dress once a month, water normally in between
- Soil biology handles nutrient availability, most growers skip pH adjustment
- No salt buildup, no flush needed, organic inputs only
- Available in 500g, 2 kg, 10 kg, and 20 kg to fit any grow size
- Slow-release formula is forgiving, hard to burn plants at recommended rates
- Feeds the soil food web: microbes break down ingredients and deliver nutrients on demand
One top-dress per month replaces a feeding schedule Top-dress & water
The blend includes fast-release ingredients like blood meal alongside slow-release minerals like greensand, so one application feeds plants for 3 to 4 weeks without reapplying. No bottles, no syringes, no pH pens.
Balanced 4-4-4 NPK with 75% fast-release nitrogen
3% of the 4% nitrogen is water-soluble for quick uptake in the first week. The remaining 1% is water-insoluble and becomes available as soil microbes process it, giving plants a fast start plus steady background feeding.
4.5% calcium and 2.3% sulfur already included
Calcium from bone meal, fishbone meal, oyster shell flour, and gypsum. Sulfur from potassium sulphate and gypsum. These are the two secondary nutrients most often missing from standard potting mixes, and both are included here.
Glacial rock dust and basalt for iron, magnesium, and trace minerals
Glacial rock dust comes from ice-age moraine deposits, basalt rock dust from volcanic rock. Together they supply iron, magnesium, manganese, and dozens of trace elements that single-source fertilizers miss.
Kelp meal for stronger roots and better transplant recovery
The kelp in this blend is Ascophyllum nodosum, a species harvested from cold North Atlantic waters. It contains natural plant growth compounds that promote root branching, help plants recover faster after transplant, and improve tolerance to heat and drought stress.
Alfalfa meal, insect frass, and humic acid feed the soil food web
These three ingredients act as food for beneficial fungi and bacteria in the root zone. A healthy microbial population means nutrients stay locked in the soil instead of washing out the bottom of the pot every time you water.
Full Ingredient List (16 ingredients)
Feather meal, alfalfa meal, bone meal, blood meal, glacial rock dust, natural rock phosphate, fishbone meal, mineralized phosphate, potassium sulphate, insect frass, basalt rock dust, humic acid, gypsum, kelp meal (Ascophyllum nodosum), oyster shell flour, greensand.

What the math looks like
Pre-mixing soil
At the recommended 3 tbsp per gallon, a 5-gallon pot uses 15 tbsp (about 1 cup) per fill. A 10-gallon pot uses 30 tbsp (about 2 cups). Even the 2 kg size pre-mixes multiple pots before you need to reorder.
Monthly top-dressing
At 1 tbsp per gallon, a 5-gallon pot uses 5 tbsp per month. That's a fraction of the tub per application, so even the smallest sizes last many months of monthly top-dresses across several containers.
Raised beds and gardens
Gaia Green recommends 5 lbs per 100 sq ft for garden beds. One tub covers about 88 sq ft per application, roughly a 9x10 ft plot.
How to use it: pre-mix, top-dress, transition, repeat
Pre-mix into fresh soil before planting
Blend 3 tablespoons per gallon of potting mix. Distribute evenly, moisten the soil, and let it sit 24 to 48 hours before planting so microbes can begin breaking down the ingredients.
Top-dress once a month during vegetative growth
Sprinkle 1 tablespoon per gallon of soil on the surface. Scratch lightly into the top half-inch and water in. Between top-dresses, just water normally.
Switch to Power Bloom when plants start flowering
Transition your top-dress to Gaia Green Power Bloom 2-8-4 for the higher phosphorus and potassium flowering plants need. Many growers run 50/50 at the transition, then 100% Power Bloom for late flower.
Re-amend and reuse spent soil
After harvest, pull the root ball, mix 3 tablespoons per gallon of 4-4-4 back in with a cup of worm castings per gallon, and let it sit moist for 2 to 4 weeks. The soil is ready for the next plant without buying fresh media.
- 500g (1.1 lbs): Trial size, enough to top-dress a few pots for one cycle
- 2 kg (4.4 lbs): Most popular for home growers, lasts multiple cycles in containers
- 10 kg (22 lbs): Multi-cycle supply for serious home or small commercial grows
- 20 kg (44 lbs): Best per-pound value, covers large gardens or commercial operations

- Power Bloom 2-8-4: Higher P and K for the flowering stage. Use after transitioning off All Purpose.
- All Purpose + Power Bloom bundle: Both products at a discount. Covers veg through flower.
- Gaia Green Worm Castings: Inoculates your soil with beneficial microbes that help break down the dry amendment faster.
