Best Cannabis Fertilizers & Nutrients for Outdoor Grow

Last Updated: June 16, 2022By Joshua Mezher

Growing cannabis outdoors may seem straightforward, but there’s a lot you need to know. Specifically, you’ll need to think about the supplies and tools you’ll need to grow healthy plants. 

You’ll also want the best nutrients for outdoor grow situations – for both the vegetative and the flowering stages of a cannabis plant’s growing cycles.  

The primary nutrients that cannabis plants need are nitrogen, potassium, and phosphorous. Also known as NPK. During the vegetative stage, these plants require more nitrogen nutrients. During the flowering stage, they need potassium the most.

As a grower, you must ensure your plants consistently receive enough nutrients, water, soil, and sun as they grow to produce an ample harvest.

What Types of Fertilizers Can Be Used to Grow Cannabis?

Growers can use two types of fertilizers on their cannabis plants: salt-based fertilizers and non-salt-based (organic) fertilizers.

Salt-based fertilizers are usually manufactured in laboratories, while organic fertilizers come from any natural components which can be recycled back into the soil. These natural components include fish bone meal, veggie, and animal manure compost.

While both fertilizers are efficient at increasing plant growth when used properly, salt-based fertilizers are more consistent. Organic fertilizers may produce varying results. 

Salt-based fertilizers are also bio-available, which means the plants can easily absorb them from the soil. On the other hand, most organic fertilizers are granular-based and solid, which means they need some time to break down entirely before the plants can absorb them.

However, if you aren’t using the best soil as your fertilizer option, here are some products with the best nutrients for outdoor grow for you to consider:

Roots Organic

The Roots Organic nutrient line ranges from dry to liquid formulations for cannabis plants. This organic brand’s base nutrients are Buddha Bloom and Buddha Grow. The ingredients include all-natural nutrients, such as yucca extract, worm castings, molasses, soy extract, kelp extract, bat guano, and rock phosphate.

We really like their dry amendments, specifically their Terp Teas. They are soil compatible! 

Despite being a bit on the expensive side, the Roots Organic line has various options, making it one of the best nutrients for outdoor grow conditions.  

Nectar of the Gods

This all-natural product line includes a range of options to meet the varying needs of cannabis growers. Their options include Medusa’s Magic, Athena’s Aminas, Gaia Mania, Demeter’s Destiny, and the Kraken, among many others.

Despite being pricey, the Nectar of the Gods cultivation line is worth its hype. These products are well suited for personal grows and absorb easily. However, you may need some practice to fully take advantage of these products’ numerous benefits. When choosing what product to purchase from this line, it is essential to consider what your plants need - each product addresses a specific area of need. 

Bio Bizz

This organic product line consists of more than 15 all-organic products which provide the best nutrients for outdoor grow situations. 

Bio Bizz products include pH regulators, stimulants, fertilizers, activators, boosters, strengtheners, supplements, substrate enhancers, substrates, starters/try-packs, and dry fertilizers.

These products are suitable for first-time growers or beginners. The company provides numerous grow guides – which are helpful for learning how to grow healthy and thriving plants. 

While they retail on the higher side of the price range for cannabis fertilizers, the numerous positive reviews show just how effective they are.

There are many things to consider when growing cannabis plants – including your ideal fertilizer. Organic fertilizers and salt-based fertilizers are each effective in their own ways, depending on how you use them and what issue they are addressing. Organic fertilizers, which are rich in nitrogen and phosphorous, are best used in outdoor gardens, especially when combined with liquid nutrients. Additionally, it is important to remember that some salts may harm your plants. This is why you should ensure that you only use the best nutrients for outdoor grow gardens, regardless of your choice.

However, if you want to keep it simple and affordable, stick to a Pot for Pot’s Superb Soil which is included in every one of our grow kits for cannabis. Our ready-to-use use soil mix will take the hassle out of ensuring that your cannabis plants have the best possible medium to grow in.
