What is Reefertilizer?

Founded in 2017, we are dedicated to making it easier for people to start growing their own weed.

Reefertilizer’s three-step nutrient kit is crafted to help cannabis plants thrive during each stage of cannabis growth; Sprout, Veg, and Flower.

Reefertilizer Start is dry organic sea kelp infused with beneficial mycorrhizae. Adding a few scoops early on is fantastic for establishing a strong healthy root system.

Reefertilizer Grow and Bloom are concentrated blends of micro and macro-nutrients proven to be essential for cannabis growth and flowering.

Our guides and articles will also take your garden to the next level and get you one step closer to becoming a master grower.
