Homemade Fertilizers For Outdoor Grow

Making your own fertilizer for your outdoor garden can save you money and improve your yields. If you're making your own cannabis nutrient mix, consider the most important macronutrients for the plants: nitrogen (N), phosphorus (P), and potassium (K).

In addition, your plants also need a variety of micronutrients including calcium, iron, zinc, magnesium, copper, manganese, cobalt, and many more to thrive. Using the right fertilizer when growing cannabis is essential for any weed grower and plants.  

Macronutrient Sources

  • Nitrogen: Nitrogen, an important nutrient especially during the vegetative phase, can be sourced from a variety of organic sources including worm castings, animal manure, bat guano, or crustaceous meal. A nitrogen deficiency can be a nightmare for growing cannabis. 
  • Phosphorus: If you're looking to add phosphorus to your nutrient mix, boiled banana peels, chicken manure, bone and fish meals, and rock dust are an excellent source of phosphorus.
  • Potassium: If you want to add potassium to the mix, bat guano, fish meal, wood ash, banana peel, kelp, and compost are all excellent potassium sources.

Micronutrient Source for Marijuana Plants

Micronutrients may only be available in trace amounts but they still are an important part of your cannabis plants growth.

  • Calcium: Calcium can be found in sources like chalk, clay, limestone, and gypsum.
  • Magnesium: Magnesium sources include dolomites and epsom salts.

Top Nutrients for Outdoor Cannabis Gardens

Cannabis growers have many nutrient brands to choose from, which can make deciding on a single one quite difficult. 

In addition, each nutrient company makes a range of nutrients for different purposes. Since cannabis plants require different nutrient levels for their vegetative and flowering stage, nutrient companies create different formulas for each stage.

Generally, all cannabis nutrients are meant to improve the health and growth of your plant. However, there are a few key differences between the different nutrient solutions out there. Here's what to look for in your nutrients for cannabis plants:

  • Nutrient ratio: Every company has a slightly different ratio of the plant's most critical macronutrients for each stage of growth.
  • Growing medium: For outdoor gardens, you'll be choosing nutrients meant for soil not hydroponic gardens, which are common for indoor grows. Make sure you're getting the right one to avoid any confusion down the line.
  • Ingredients: There are many sources of nitrogen, phosphorus, potassium, and other important micronutrients. These ingredients can range from synthetic to organic nutrients. It's important to consider the types of nutrient sources used. While different brands can have the same level of nutrients, they may differ in where those nutrients come from. Make sure to keep these in mind when choosing cannabis nutrients for your plants. 

A note on supplements: Now, it can get quite confusing if you factor in the different types of nutrients supplements available.

Unlike the complete nutrient solutions, supplements contain only a fraction of the required NPK ratios to let you either fix a nutrient deficiency or enhance a certain aspect of your growth including size, resin content, and potency.

Ideally, you want to use supplements made from the same brand as your nutrients. In addition, only use supplements if absolutely needed. Feeding your marijuana plants too much nutrients can cause nutrient burn or other damaging interactions.

If you're in the market for a reliable nutrient solution, consider these nutrient brands for your outdoor cannabis garden:
