What are the best cannabis nutrient brands?

While cannabis may not be the hardest plant on earth to grow, there are a few things needed in the grow room in order to let cannabis thrive. One of those things is the proper nutrients. All plants need nutrients to survive. Some get them naturally from the soil while others use a supplement to make sure their plants are getting what they need. Others make their own nutrients whether they come from household items, compost, or another homemade solution. In fact, this is a very popular option for those growing cannabis.

But for those that are just starting out growing, purchasing ready-made nutrients can be a much easier option. Most cannabis nutrients are affordable, come with full instruction, and can do a world of good for your grow room. Here we’ve reviewed the top three most popular nutrients to help you and your plants.

What are the three main nutrients cannabis needs?

Before you grow its important that you understand the basics. And at the core of every big yielding cannabis grow is a solid foundation of macro nutrients; Nitrogen (N), Phosphorus (P), and Potassium (K). Often referred to as the N-P-K ratio:

Nitrogen (N): Vital during the vegetative stage, nitrogen promotes strong leaf and stem growth. A deficiency can result in yellowing leaves and stunted growth.

Phosphorus (P): This nutrient is very important during the flowering phase. It aids in the development of healthy roots and big buds. Insufficient phosphorus can lead to delayed maturity and smaller flowers.

Potassium (K): Supporting overall plant health, potassium ensures strong cellular functions and resistance against diseases. A lack of potassium will often display itself as brown spots or curled leaf edges.

Week by week NPK ratio guide

Each nutrient brand will have different guidelines as to how much to give to your plants, the amount will also vary depending on if you are growing autoflowering seeds or photoperiods. Autoflowers only require about a third to a half of the nutrients as they are much smaller. Here is a table showing what a week by week schedule could look like if you were to grow a cannabis plant on a 12 week schedule.

What nutrient makes cannabis buds bigger?

To grow plump, dense buds, the key nutrient to focus on is Phosphorus. During the flowering stage, an increased phosphorus intake can lead to bigger and denser flowers. Alongside phosphorus, Potassium (K) also plays a key crucial role at strengthening the plant cells aiding in nutrient uptake. Together, they enhance energy transfer, resulting in bigger yields. Using bloom boosters or flowering enhancers, rich in both nutrients, can make a noticeable difference.

Should I use nutrients every time I water?

The simple answer is no. Consistently providing nutrients with every watering can lead to nutrient build-up in the soil, eventually causing "nutrient burn," which will cause yellowing leaves and eventually stunted growth. Instead start with a diluted nutrient mix, gradually increasing as your cannabis plants grow. Implement a routine of alternating between nutrient-rich water and plain pH-balanced water. This helps plants to get essential nutrients without the risk of overfeeding.

What do we think are the best nutrient lines?

Advanced cannabis nutrients

Advanced Nutrients is one of the more expensive nutrient options out there, with 250 ml costing between $20 and $25. But once growers understand the many benefits of this very popular brand, it’s easy to see why so many choose it over the others. Advanced Nutrients is perfectly suitable to any strain of cannabis and while seasoned growers have come to love it after seeing the effect it has on their grow room, it’s great for beginner growers too.

For those beginners Advanced Nutrients also supplies a starter pack that includes nutrients for each stage of growth. This starter pack includes Big Bud, B52, Voodoo Juice, and Overdrive – all products that are prepared by Advanced Nutrients and are known to be some of the best on the market. Each individual nutrient is used during a different period of growth, giving cannabis plants exactly what they need when they need it. When used as directed, anyone can get bigger, more beautiful cannabis plants.

Fox Farm cannabis nutrients

Those who don’t like the price tag of Advanced Nutrients may feel better about it after doing some comparison shopping and finding that Fox Farm sell for even more at around $35 for just a one-litre bottle. But, Fox Farm is just as good a brand as Advanced Nutrients and its biggest fans will likely tell you it’s even better. We find it pretty comparable. Like Advanced Nutrients, Fox Farm is a multi-part system with different aspects of nutrients being sold separately. Unlike Advanced Nutrients however, each of these three different aspects are applied during each growth phase.

What these nutrients provide is cannabis that has thick, dense buds; and the entire plant is lush and green throughout to boot. In addition, Fox Farm is can also be a huge help in preventing calcium and magnesium deficiencies, which is something many cannabis plants can suffer from.

When using Fox Farm, it’s important to remember that each component is quite strong in its own right and so growers should never overdo it. Like most nutrients on the market, Fox Farm comes with its own instructions for use and it is highly recommended that these are strictly adhered to in the grow room.

Is Fox Farm good for growing weed?

Fox Farm offer a diverse range of nutrient solutions tailored for each of the cannabis growth stages. They have been around since 1984 and are well known as one of the best cannabis nutrient brands.

There is a lot in a grow room that can be tricky, particularly for beginners. But in the case of nutrients for cannabis, it doesn’t have to be. While there are many great options available, there are also some that are better than others. Ease of use, cost, and of course, how cannabis grows when using them will all be factors when choosing the right nutrients for your plants. But when choosing any of the above three, both the grow room and the cannabis will benefit.

Dyna-Grow nutrients

Dyna-Gro has a lot to offer but perhaps the best thing is that it doesn’t matter what medium the cannabis is growing in. Soil, coco coir, and hydro setups will all do very well with Dyna-Gro. And a quart of Dyna-Gro will cost about $25 so it’s on par with Advanced Nutrients and costs just a little less than Fox Farm.

In addition to being perfectly suitable for all types of setups, Dyna-Gro is also appropriate for both the vegetative and flowering phases of growth. Each of these phases do have different nutrients however. Foliage-Pro should be used in the early stages when the plant is still in its vegetative stage; and Bloom can be used once the cannabis enters its flowering stage.

It contains 16 essential minerals, a blend of micro and macro nutrients, and is quickly absorbed by the plants so they are more evenly distributed throughout the soil. Growers that have other types of plants outside the grow room will also find that Dyna-Gro is perfectly suitable for those plants as well.

While there are two different lines of Dyna-Gro available for different growth phases, once you have the right product it’s all ready to be used right out of the bottle. So there’s no mixing of chemicals in the grow room, just following instructions on a bottle. Doing so with Dyna-Gro will produce thick buds and can even enhance the taste and smell of the cannabis grown with it.

What are the best nutrients for the veg stage?

Lots of growers put more focus on the flowering stage, with the assumption that this is the stage where the buds grow and so it should get the most attention.

Dosaline Grow from Future Harvest stands out as the number one choice. It is an exceptional product that has been specifically formulated for the vegetative phase, tapping into the potent benefits of Ammonium Sulfate, Diammonium Phosphate, and Potassium Nitrate.
