You are what you eat! This adage refers mostly to humans of course, but it stands just as, if not more, true for cannabis. Well-made nutrients are a bit of a headache to browse through, especially since all that goes into them is fairly complicated.
Most nutrients have dozens of ingredients listed. It makes sense to stick to things that are more natural because chemical interactions can get fairly complex causing pH issues and more if the grower isn’t careful.
We’ve looked through the current product line-ups on the web, and tried to find the nutrients with the best track record and best ingredients from our experience.
Let’s go over our reviews of the best products we could find this year.
|Best Overall||General Hydroponics Flora Grow||
|Best Value||Advanced Nutrients Big Bud Liquid Fertilizer||
|Premium Choice||Eco Organics My Weed Minerals||
|General Hydroponics GH5100 General Organics Go Box||
|Easy Weed Soluble Seaweed Blue Planet Nutrients||
When speaking of nutrients with a proven track record, General Hydroponics is a great product that needs to be mentioned. They’ve been in the game since the late 1970s producing some of the finest indoor plant nutrients on the market. They were even used by NASA for a few projects in Antarctica, so there’s not much better for a general and reliable product. It’s a safe choice and comes at a fairly modest price tag as well.
This isn’t the nutrient of choice for the biggest possible, dankest yields of all time. But, for amateurs who just need healthy plants, General Hydroponics is a smart pick.
Big Bud is another well-known product that should be noted as well. What it offers is sort of a booster for flowering plants. This will take a medium grow and make it quite a bit larger when used as directed.
The caveat is that it should only be used on plants that made it through the vegetative stage healthy anyways. It can be a bit much for struggling plants and isn’t recommended as a way to bring something back to its peak health. When used as an addition to already thriving plants, it can really help increase flowering stage yields.
Price-wise this isn’t much of an investment and is a good tool to have on any grower’s shelf towards harvest season and makes it one of the best Cannabis nutrients for the money.
An excellent choice for those who don’t mind spending a bit extra, and want a fertilizer that will last them from sprouts to flowering with good results the entire way. Eco Organics is an excellent product that is a great all-around choice, while also being great at creating large, dense buds during flowering stages.
It’s actually fairly rare to find one that handles the whole growth of a plant this well. It’s very appreciated. Being said, it’s not going to make up for improper care or skimping on other parts of the grow. So, if it’s a choice between this and, say, better lighting, then these nutrients shouldn’t be the priority.
It shines in already established grows, which is why it isn’t the number one on the list. It’s a bit of a splurge for those who are already guaranteeing great results without fancy nutrients such as Eco Organics, which is great, if expensive, choice for all-around nutrients.
Another, but a bit more nuanced, product from General Hydroponics. This is a solid choice for beginners that provides a nutrient for every stage of the grow. This only misses the top of the list due to the added complexity compared to something like the Eco Organics product.
Multiple bottles need to be used and switched between throughout the growing process. Though it does walk you through when to use each, there’s plenty of room for user error and potentially stunting plant growth in new farmers.
It feels like a product meant for beginners, that requires a bit of expert knowledge to get right.
One of the most organic products on the market, this solution is a mixture of kelp plants turned powder that provides health, natural nutrients to growing plants. Easy Weed has designed this specifically for non-soil grows, such as hydroponics, to add into a nutrient broth.
Much like the first item on the list, this isn’t the best product to use when aiming specifically for dense yields. However, it is a safe choice that will provide a healthy life throughout all stages of growth when used appropriately.
It’s on the cheap side as well, which is nice for a product as natural as this.
Even more niche than the last item mentioned, but Element Flower Fuel does indeed provide big buds during a soil-less flowering stage. This shouldn’t be used throughout the entire growth of your plant but, when added in the appropriate amount once the buds start to bloom, it can seriously create some dense flowers.
It’s a great product for hydroponic growers that wish to step up their game towards the end of a grow. This is very concentrated stuff, so watch out for shocking plants by adding too much to their water.
Middle price ranged, all-purpose fertilizer that touts huge buds but doesn’t quite live up to other products on the market. Humboldts Secret is a fairly famous brand, but this particular product seems to be getting usurped by others on the market these days.
The price of it is a bit much for something that doesn’t have marked improvements over other all-around fertilizers and the acidity of it makes it a bit of a pain to deal with. If using this watch your soil’s pH, as it tends to rise over time with this product. It’ll still work, we’re just not sure if it’s the ideal product for the price.
A safe-bet from a known product line, but is a bit pricey and doesn’t have the results of products within the same price-point. This is a three-step solution, so user-error can also come into play on this one, which does indeed create some pretty nice plants at the end of harvest. However, for the premium price something like Eco Organics’ product, number 3 on this list, does a better job and works from day 1 of the grow.
Fox Farm hits the bottom of the list simply because it doesn’t have a leg-up on any of its competitors, though it’s still a safe choice for new growers.
We look at quite a few different aspects of a nutrient when deciding on our recommendation.
Every plant is different and every grow needs to be carefully measured out before adding any nutrients to the mix. These problems get compounded when the mixtures being used need multiple stages of measurements and calculations to ensure there will be no risk to the plant.
We want something that’s not complicated to use and is going to have good results without having to worry about scorching the plant with some strange compound that they didn’t react well to. A multi-step process isn’t necessarily a deal-breaker, but it does open up the door to user error and miscalculation. This can be disastrous and can harm even thriving plants very quickly.
Overpriced nutrients litter the market with claims that really don’t size up to the price tag. That isn’t to say there aren’t products that are worth the money, but going all in on some fancy brand of fertilizer isn’t going to magically turn a bad grow great.
We also believe that a plant isn’t going to grow well, despite great nutrients, if the budget on more important grow-op materials is cut in exchange for more expensive fertilizers. Because of this, a heavy emphasis on the budget is taken into account.
None of this means the cheapest option is always the one to go for, it just means an expensive nutrient shouldn’t be the reason to down-grade your ventilation system plants or some other similar measure.
The nutrients that are being used can range from things like basic organic composts to complex compounds that target specific aspects of a plant’s growth. To get the most out of a plant through nutrients, figuring out exactly what you want from a plant and what your plants are ready for is key.
A lot of products claim to be the best at creating big buds, but if it isn’t able to rear a healthy plant to the flowering stage then it needs to be noted. There can also be issues with things like shocking the plants, completely ruining a grow through over-nutrification of the plants. This is why it’s recommended for plants to already be thriving before adding any fertilizers that are targeting bud growth.
There’s room for these products in any grower’s arsenal, but when purchasing nutrients, it’s important to know if a product is actually meant for all-around growth or if it is meant for addition later in the plant’s growth.
A good nutrient for younger plants can help a strong and powerful network of roots beneath the plant, making it stronger later on and capable of producing higher yields. However, many nutrients really aren’t meant for the early stage of a plant’s development, and can have downright problematic effects if used at the wrong point in the life cycle.
Aim for nutrients that are safe even for juvenile plants first, before working with additives that target large flowering stages.
Our best results have always been with using a good all-around, such as the General Hydroponics Flora Grow line, and then going over to a flowering nutrient once we start blooming towards the end of the cycle.
As an additive, Advanced Nutrients GL525050-12 Big Bud Liquid Fertilizer is a great choice and has consistently worked well on our plants. The buds take to the compounds they use in this, and it becomes evident fairly quickly.
Make sure not to over-do it with any of these products as well. Plants respond well to an appropriate amount of nutrients, but too much will harm them fairly quickly.
A bit of food goes a long way for a cannabis plant.
We hope this helped somewhat in navigating all these products. Not all are created equal, so a bit of extra input like this can be a big boon to selecting the best one for a grow.
