One of the most common questions we get from beginners is,

What do those numbers mean on your bottles?

You may have noticed our fertilizer bottles have 3 numbers on the front. For example, our Super B+ says “0-5-3”.

What does this mean?

These numbers represent nitrogen (N), phosphorus (P), and potassium (K).

0 = Nitrogen 

5 = Phosphorus 

3 = Potassium 

This would mean this bottle of Super B+ contains 0% nitrogen, 5% phosphorus, and 3% potassium. 

The first number will represent the amount of Nitrogen, the second the amount of phosphate, and the third the amount of potassium. ⠀⠀⠀⠀⠀⠀⠀⠀

Nitrogen, phosphorus, and potassium, commonly known as NPK, are important nutrients when it comes to cannabis cultivation. They are considered the 3 macro nutrients essential to plant growth.⠀⠀⠀⠀

However, there are other essential macro and micro nutrients you will need in order to grow a strong and healthy plant!

Potassium in fertilizers is sometimes referred to as Potash. Potash comes from mined salt high in potassium. ⠀⠀⠀

Nitrogen is essential to the plant because the majority of chlorophyll is made up of nitrogen. Nitrogen helps to build protein in the plant so it can grow big and strong. Through chlorophyll production, nitrogen helps the plant to form healthy green leaves. ⠀⠀

Plants need extra nitrogen in the vegetative stage so you’ll find that reflects in feeding schedules. ⠀⠀

Phosphorus helps your plant grow big buds. Because of this, feed schedules usually provide extra phosphorus in the flowering stage. Our BUD START and TON-O-BUD contain a phosphorus boost for your plant so you can grow those big buds you’ve been dreaming of. ⠀⠀

Potassium helps your plant to absorb water and nutrients. It also helps in bud production! Because of this, potassium levels should be higher during flowering. ⠀⠀

Most high quality nutrients will come with a feed schedule. These feeding schedules will already have the NPK values spread out among the vegetative and flowering stages.

If you wanted to create your own feed schedule, you’d want to follow something similar to this.

Now that you know how to read a nutrient label… let’s practice!

Here we have our Holland Secret 3-Part. These nutrients are designed to be used together at different concentrations throughout your plant’s life cycle. Try to guess which nutrient would be used in a higher concentration during Flowering or Vegetative!  Answers will be at the bottom.
