Best Hydroponic Fertilizer Reviews: 5 Fertilizers For Your Hydroponics System
Planning to grow plants or crops in a hydroponic system? Here’s our list of the best hydroponic fertilizer products to help you yield great results.
Growing vegetables and other plants through a hydroponic system is economical. It allows you to save a lot of time, effort, and of course, water. However, just like growing plants in a typical garden soil, you will need the best hydroponic fertilizer to provide them with the grow nutrients they need.
Hydroponic fertilizers are one of the most important purchases you need for growing your plants. The right nutrients in the right proportions will drastically affect the quality and quantity of your harvest. For a newbie grower, it’s quite challenging to use hydroponic nutrients for vegetables and any other crops since every component has to be water-soluble.
For this reason, we researched the best hydroponic fertilizer products and reviewed them for your own convenience. We’ve also included some important things you need to know about hydroponic nutrients along with a quick guide to choosing the right nutrients for your garden.
Why Use Hydroponic Fertilizers?
Fertilizers that are designed for soil have a different composition as compared to the ones for hydroponics because soil-based plants can easily get most of the required elements directly from the soil. With hydroponics, there is no soil for your plants to get elements from. For example, nitrogen is not readily available for plants in a hydroponic system since urea (which is the main source of nitrogen) is not water-soluble. Due to this, nitrogen should be delivered in its nitrate form for plants to absorb in a hydroponic environment.
Do Hydroponically-grown Vegetables Taste Better?
You might have heard that crops grown through a hydroponic system have a bland flavor. If you plant the same crop naturally in an outdoor garden and hydroponically in an indoor garden, you might not notice any difference in their flavors at all. The only thing that could make a slight difference in their taste is the choice of fertilizer you use for growing them. However, you don’t have to worry – vegetables that are grown hydroponically won’t have the bland flavor as what others believe.
Which is Better: Liquid or Powdered Fertilizers?
Before we even tackle about the right way to choose a hydroponic fertilizer, you should first keep in mind that hydroponic fertilizers are available in two different forms: liquid and powder. If you’re a newbie grower, you might want to go for an easier option which is a liquid solution. Although it is a bit more expensive, it does help save your time and even effort! Meanwhile, commercial hydroponic growers tend to go for powdered forms since they produce bigger yields. The problem is, it will take a certain level of skill to master.
Liquid nutrients are commonly used by hobbyists for their hydroponic systems since they make the entire process quick and easy. Since they’re already premixed, there’s no longer a need to mix up a powder fertilizer and spend time in doing so.
On the other hand, powdered or dry hydroponic nutrients are commonly sold as a two-part powder mix. The first part consists of calcium nitrate while the second part contains the main nutrient mix. If you go for a powder mix, you need to mix the two powders in separate containers then combine them to form a solution. Most of these two-part powder mixes are complete solutions, although there are some that need another compound added as well.
Despite more complicated, powdered mixes are way affordable as compared to liquid solutions. Since the latter is mostly water, shipping them will require you to pay extra depending on how many volumes you’ve purchased.
Commercial hydroponics systems use powdered nutrients since they don’t have to pay for expensive shipping costs. Moreover, they can get mixes that are formulated specifically for weed, vegetables, strawberries, etc. (although this also applies for liquid fertilizers).
A Few Tips For Hydroponics Growers Who Use Nutrient Solutions For Fertilizer
If you’re more inclined to use a nutrient solution from one of the best hydroponic fertilizer products in our list, you need to know a few tips to help make your gardening experience as enjoyable and fruitful as possible. Some of them are as follows:
- To achieve the best results, check how hard your water is in PPM. Through this, you can easily manage the levels of acidity and alkalinity.
- If you’re going to use chlorinated tap water, make sure to reduce its chlorine content by leaving it to sit out for an entire day at room temperature.
- Metal might be a durable material to use for your hydroponic system. However, it could interact with your nutrient solution in an adverse manner. Use plastic for a safer choice instead.
- After a successful harvest, make sure to clean every part of your hydroponic system to ensure old nutrients don’t get mixed in with the new crops.
- Make sure to keep the temperature in check. Plants will be able to benefit more from your fertilizer if both the solution and water used are between 68 to 72 degrees Fahrenheit.
Factors To Consider When Buying Hydroponic Fertilizers
Choosing the best hydroponic fertilizer for your plants is one of the most important decisions you should make as a grower. But before you do so, you need to consider some important factors to help your plants achieve its maximum growth potential. Ultimately, it all comes down to the type of plants or crops you plan to grow, and to what size. To help you with that, here are some factors you have to keep in mind:
Nutrient management is the crux of a healthy hydroponic system.
1. EC Levels
EC levels or electrical conductivity is the number of nutrients your system currently have at a given point. Typically, you will need your EC level to be around 1200 to 1500 parts per million. By making sure your nutrients are in the ideal range, you will be able to produce healthy and robust plants.
2. Fertilizer Type
Like a non-hydroponic system, hydroponic systems also require the use of fertilizers. After all, this is where plants and crops can get the nutrients they need for proper growth. As mentioned earlier, there are two different types of fertilizers, and your choice of a fertilizer will depend on what and how you like your crops to grow.
For small areas such as a backyard, you might want to consider using liquid fertilizers. Since they are already premixed, you can easily use them without any problem at all! Meanwhile, if you have a large area, it is recommended to go for a powdered mix. Unlike liquid fertilizers, powder fertilizers are available in two parts. Before you can use them, you need to mix each part in separate containers and combine them together afterward before applying to your plants and crops.
Although powder fertilizers require a bit more skill to handle, they will help you save money as compared to liquid solutions.
3. pH Levels
pH level is yet another important factor you need to consider in order to maintain the health of your plants and crops. Depending on what you grow, you need to find out if your plants or crops will need more acidic or basic levels.
4. Organic or Synthetic
Organic fertilizers are the ideal choice for soil-based gardens since organic nutrients contain some elements that could clog up pumps and small tubes. Although some tests are being conducted to introduce organic fertilizers to hydroponics, a synthetic fertilizer is still considered the best option for now.
Synthetic nutrients are basically the most common nutrients used in hydroponics systems. One of the reasons is because they are easily broken down into smaller particles that can be easily absorbed by plants. However, it doesn’t necessarily mean they have more nutrients, just that they are absorbed more quickly.
5. Current Growth Stage
During a plant’s vegetative stage, it will require a lot of nitrogen to help it grow tall and leafy. Meanwhile, as it starts to enter flowering stage, you need to stop providing it with nitrogen and instead focus on providing more phosphorus and potassium, along with calcium and magnesium for producing bigger and more colorful flowers.
6. Your Budget
This one might be subjective, which is why you need to do some shopping and price comparison to find the best hydroponic fertilizer that could fit your budget. As long as your preferred fertilizer has all the nutrients you need, you won’t have to spend a lot of money on expensive products.
