Three powders.
One clear schedule.
Reefertilizer covers the three things a plant needs over its life — root development, vegetative growth and flowering — with one product each.
One product for each stage.
Reefertilizer Start
Organic kelp meal coated with mycorrhizal spores. Mix it into the soil at transplant so roots establish quickly.
Explore Start
Reefertilizer Grow
Water-soluble nitrogen-rich feed with chelated micronutrients for strong stems and a healthy canopy.
Explore Grow
Reefertilizer Bloom
High phosphorus and potassium to support dense, aromatic flowers through the final weeks.
Explore BloomThree steps, start to harvest.
Find your week
Every stage has one row on the feeding chart — seedling, veg or flower.
Mix and water
Stir the scoops shown for that week into your water and feed. Check pH as you go.
Repeat to harvest
Move down the chart each week. Ask us if something looks off — we answer.
Simple by design.
Why three powders is enough
A cannabis plant needs different nutrients at different points in its life. Young plants want root development, veg plants want nitrogen, and flowering plants want phosphorus and potassium. Reefertilizer covers those three needs with one product each.
Why powder instead of bottles
Liquid nutrients are mostly water — you pay to ship it, store it and throw the bottle away. Dry nutrients weigh a fraction of a liquid line-up, a little goes a long way, and they keep for years if stored dry.
Indoor, outdoor, soil or hydro
Start is an organic soil amendment. Grow and Bloom are fully water-soluble, so they work in soil, coco, hydroponic, aeroponic and DWC systems.
If something goes wrong
Yellowing, burnt tips, slow growth — most of it is fixable if you catch it early. Send us a photo and a grower will take a look.
Everything your grow needs.
Nothing it doesn’t.
Start, Grow and Bloom — one clear feeding schedule from seed to harvest. Enough for up to eight plants.
