High phosphorus for the flowering stage. Same simplicity as All Purpose, tuned for bloom.
Gaia Green Power Bloom 2-8-4 is the flowering counterpart to All Purpose 4-4-4. Where All Purpose handles vegetative growth, Power Bloom delivers 8% phosphorus and 4% potassium from 14 organic ingredients to support flowering, fruiting, and root development. Top-dress once a month during bloom, or blend it with All Purpose at the transition. Organic growers have relied on this exact two-product system for over 20 years.
- Another bottle to buy on top of your base nutrients
- Measure and mix at every watering during flower
- Easy to overshoot and lock out other nutrients
- Salt-based P and K build up and require flushing
- No secondary nutrients or trace minerals included
- Feeds the plant directly, bypasses soil biology
- One product replaces PK booster, bloom base, and supplements
- Top-dress once a month, water normally in between
- Slow-release formula is forgiving, hard to burn at recommended rates
- Organic inputs, no salt buildup, no flush required
- 4.5% calcium, 2.3% sulfur, plus trace minerals from rock dust and greensand
- Microbes break down ingredients on demand, nutrients stay in the root zone
8% phosphorus from four different sources 2% N, 8% P, 4% K
Bone meal, mineralized phosphate, fishbone meal, and rock phosphate each release at different speeds. That spread ensures phosphorus availability from the first week of flower through the final weeks of fruit set.
Low nitrogen, mostly slow-release, to avoid excess foliage in bloom
Only 2% total nitrogen, and 75% of that is water-insoluble (the opposite of All Purpose). This means a slow, steady background feed of nitrogen without the vegetative push that flowering plants don't need.
4.5% calcium and 2.3% sulfur already included
Calcium demand spikes during flower, especially around weeks 3 to 5. Bone meal, fishbone meal, and gypsum provide it here without adding a separate cal-mag supplement.
Glacial rock dust and basalt for trace minerals during heavy production
Flowering and fruiting plants pull hard on iron, manganese, and magnesium. Both rock dusts supply these trace elements along with dozens of micronutrients that single-ingredient bloom boosters miss.
Insect frass and humic acid keep the soil food web active through harvest
Late in flower, soil biology can slow down as organic matter gets consumed. Insect frass and humic acid act as food for beneficial microbes so nutrient cycling doesn't stall when plants need it most.
Pairs with All Purpose 4-4-4 for a complete veg-to-harvest system
Use All Purpose 4-4-4 during veg, then transition to Power Bloom at the flip. The two products share the same application rates, so switching is just swapping which tub you reach for.
Full Ingredient List (14 ingredients)
Bone meal, mineralized phosphate, fishbone meal, rock phosphate, mined potassium sulphate, glacial rock dust, insect frass, feather meal, basalt rock dust, kelp meal (Ascophyllum nodosum), humic acid, gypsum, greensand, blood meal.

What the math looks like
Monthly top-dressing in bloom
At 1 tbsp per gallon, a 5-gallon pot uses 5 tbsp per month. A 2 kg tub gives you roughly 7 months of monthly top-dresses for a single 5-gallon pot.
Pre-mixing flower soil
At 3 tbsp per gallon, one 2 kg tub pre-mixes about 60 gallons. That fills twelve 5-gallon pots at under $1.10 per pot.
Full cycle cost (veg + bloom)
One tub of All Purpose ($10.95) plus one tub of Power Bloom ($12.95) covers a full veg-to-harvest cycle for multiple containers. The bundle saves even more.
Compared to liquid bloom boosters
A bottle of Botanicare Hydroplex runs about $20 for 1 quart and still requires a separate base nutrient. One tub of Power Bloom at $12.95 handles the entire flowering stage on its own.
How to use it: transition, bloom, and re-amend
Transition at the flip with a 50/50 blend
When plants begin showing flowers, top-dress with a 50/50 mix of All Purpose and Power Bloom at 1 tablespoon per gallon of soil. This provides the phosphorus boost flowering needs while keeping some nitrogen available for the stretch.
Switch to 100% Power Bloom for peak flower
After the first top-dress, go full Power Bloom for the remaining bloom applications. Top-dress 1 tablespoon per gallon every 3 to 4 weeks. Scratch lightly into the surface and water in.
Stop top-dressing 2 to 3 weeks before harvest
Because dry amendments take about a week to break down, stopping 2 to 3 weeks before harvest lets the plant use what's already in the soil without adding more. No flush protocol needed with organic inputs.
Re-amend with All Purpose for the next cycle
After harvest, pull the root ball and re-amend with All Purpose 4-4-4 plus worm castings to reset the soil for veg. Let it cook 2 to 4 weeks, then plant again.
- 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, pre-mixes ~60 gallons of soil
- 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
- Media: Pro-Mix, Fox Farm Ocean Forest, Roots Organics, coco coir, peat-based mixes, garden soil
- Plants: Tomatoes, peppers, squash, cucumbers, fruiting trees, flowering ornamentals, and any crop that fruits or flowers
- All Purpose 4-4-4: Use during veg, transition to Power Bloom at the flip. Same application rates.
- All Purpose + Power Bloom bundle: Both products at a better price than buying individually. Covers veg through harvest.
- Gaia Green Worm Castings: Add a scoop with every top-dress to keep microbial activity high through late flower.
- Full system: Check out the Soil Re-Amend Kit with All Purpose, Power Bloom, Worm Castings, Mykos, and Azos
