Cannabis Powder Fertilizer Combo

Vegetative plants and flowering plants have very different nutritional needs. While a plant is growing, it requires plenty of nitrogen. Nitrogen helps with the growth of new stems and leaves. This results in a bushy plant that can efficiently metabolize UV rays. Our Grow fertilizer is formulated to give your plants the nitrogen required, as well as various micro nutrients proven to aid cannabis growth.

A flowering plant is no longer focusing on overall growth, it is now putting energy into developing flowers. These flowers will eventually turn into buds, so a steady diet of nutrients is necessary. Phosphorus, potassium, magnesium and calcium are the heavy hitters at this stage of growth. Having ample amounts of each will result in large dense buds with amazing aroma. A lot of commercial fertilizers accomplish this with several products, we like to do it with one.

Our fertilizers are easy to use and will go a long way. A perfect gift for the grower in your family. They are ideal indoors and outdoors, and can be used in hydroponic systems.


Our Reefertilizer™ Grow marijuana fertilizer formula was made specifically for the vegetative stage of cannabis growth. It contains a full NPK ratio of nitrogen, phosphate, and potassium as well as essential micro-nutrients.  Our formula will help grow healthy and strong cannabis plants. Reefertilizer™ Grow formula is easy to use and will benefit your grow greatly

    I don’t know how well other fertilizers would have done and I don’t know what the results would have been without fertilizer at all. What I do know is that I grew big healthy plants and got a nice big harvest. What more could you ask you say? Well I certainly don’t know any other company who would answer all my questions and help me through every step of the process, and this is exactly what reefertilizer did with me – I’m a novice grower. And the price was right. I will definitely recommend reefertilizer to everybody.
