Our Cannabis Fertilizers and Nutrients

Reefertilizer Start Cannabis Soil Nutrients

Start your clones and sprouts off right with our special formulation of nutrients and mycorrhizae. A 100% organic product, and when mixed with potting soil it will help your roots hold moisture and increase the plants’ ability to take on nutrients from the soil. This is the start phase of our 3 step process and prepares the plants’ roots system to utilize our other fertilizers in the second and third step.

Reefertilizer Grow Stage Marijuana Fertilizer

In step two of our marijuana growing process, the plant will be growing larger and lusher. The right marijuana fertilizer is crucial at this stage in the plants’ development. Our Grow formula contains plenty of nitrogen which is the main component in chlorophyll and aids in photosynthesis. During this stage Reefertilizer works to create strong new leaf growth, providing nutrients as fast as your plants require them.

Bloom Marijuana Fertilizer and Nutrients

In the final stage of growing marijuana, the plant uses its energy to produce fruit (buds). Bloom marijuana fertilizer contains micro-nutrients and a high level of phosphorus. When you lighting schedule changes and you want your plants to bloom, phosphorus will help your plant turn light energy into chemical energy and promotes blooming.


Reefertilizer was made for simplicity. A successful grow may be done with just the 3 products. They can be used in conjunction with other fertilizers, but we recommend experimenting with test plants first.

Our Start soil nutrients are organic. Grow and Bloom are chemical fertilizers containing chelated elements that are soluble in water. Chemical fertilizers make essential nutrients available to the plants much faster than organic. Chemical fertilizers must be flushed from the soil prior to harvest.

Our start product is a organic soil amendment, it is not designed to be used for hydroponic grows.
Our Grow and Bloom products are both water soluble chemical fertilizers, they are not organic.
Grow and Bloom are not slow release fertilizers, adding it directly to the soil might not meet your expectations.

For a soil grow watering once a week, it’s good to begin with a low dosage when the plants are young. 1 scoop of Grow in 4 litres of water is a good start for the first week. Once the plant is larger you can starting adding more Grow to your water. Up to 2 scoops for every 4 Liters of water.
For the Bloom stage, you can use 1-2 scoops for every 4 litres of water. When your 3-4 weeks away from harvest, the plants soil should be flushed of excess nutrients. This improves the taste of the bud. Leaching the soil can be done with plain water or 1/2 scoop of Bloom or Grow in 4 litres of water.
Depending on the size of your planter and how often you water your plants, these dosages may vary.

1 bag of grow or bloom contains enough fertilizer for approximately 160 Litres (40 gallons) of water.
This amounts to roughly 40 applications for a garden of 4 plants.
Our Start product contains enough applications for 80 Litres (20 gallons) of soil.

Grow and Bloom will both work in a hydroponic or aeroponic system. You may add the appropriate amounts to your reservoir.

Depending on your water source, Reefertilizer will affect your pH slightly. You should test the pH of your water at every feeding. Make sure it’s in the 6 to 6.5 pH range for soil grows. 5.5 to 6 pH for hydroponic grows.

Unfortunately we no longer offer small samples anymore. If you require samples please contact us.

Both have their pros and cons of course. Both types will need to be pre mixed with a small amount of water before being added to your larger water vessel. Mixing a few ounces of warm water with your powder fertilizer will help it dissolve quickly.
Powder fertilizers need to be stored in an air tight container. Our bags have a high quality resealable strip, and are air tight when sealed securely.
Chemical powder fertilizers can contain higher ratios of NPK which means a little can go a long way, but if not used carefully could harm your plants. Also flushing before harvest is necessary.

We only offer the sizes we have online. We do offer a discount on larger orders. If you’re looking for large buckets for a commercial or medical grow, please contact us for a quote.

For one plant, 1 liter of water per feeding is all you need in most cases. Our feeding schedule assumes you are feeding 4 plants, thus 4 liters for our mixture. We made a chart showing how much to mix into 1 to 4 liters of water for feeding. We did the math so you don’t have to.
