Hydroponic grow systems allow you to get incredible results for growing plants indoors. They’re easy to use and most models come in kits that give you everything that you need, it doesn’t matter if you’re growing for the first time or if you’re already a professional, once you get your system everything will be easier.
Note that we have categorized each model as either a DWC type or an EAF type. Deep Water Culture (DWC) models are easier to set up and maintain for beginners while the Ebb and Flow (EAF) are more efficient and better for plants that prefer dry conditions.
What We Recommend: The Best Hydroponic System
#1. General Hydroponics Farm
General Hydroponics GH 4720 model is one of the best hydroponic systems out there, it has eight growing sites that can be filled with 11 gallons of water. If you wish, you can also expand this size up to 12, and all of this can be done on a single controller. Because of the number of buckets and their size, this system is the best one for users who have medium to large growing operations.
You’re also receiving a 12-gallon reservoir and an 8-gallon controller unit, this model can be seen as a kit because you really get all that you need for starting out. Besides that, you’re also getting installation hardware and materials as well as the brand’s Hydroponics Flora series nutrients. This particular system is an EAF type, which means that it is more efficient and better for plants that need dry conditions.

3 Key Factors When Choosing A Hydroponic System
When choosing a hydroponic system, you shouldn’t just buy the most rated one, select something that is adaptable to your needs. Consider the following traits when picking:
Although the systems you’re going to buy aren’t going to be of an industrial level, you should still consider how much room you have in order to make sure that the system can fit. Most systems with a big number of growing sites can take up to an entire room, but some small systems can even be placed on a kitchen countertop.
Since you’re converting from soil to water-based growing, the hydroponic system that you’re going to buy is going to need a lot of electricity to run. Even a standard 1,000-watt bulb in your system will cost you sometimes a few hundred dollars per month to maintain. The quality of those bulbs and other electrical components may even degrade in the coming years, so select something energy efficient in order to save money.
If you’re buying a minimalistic setup that doesn’t feature anything that supports you when growing plants, you will end up having to control how much nutrients or what temperature the plants need.
This will need to be done most of the time, and in order to prevent you from doing it all by yourself, you can buy setups that have monitoring systems, which measure things like water level, temperature, and humidity.
Benefits Of Using Hydroponic Systems
More and more people are moving onto hydroponic systems instead of traditional gardens that use soil, and there is a reason for that! The first advantage of using water instead of soil when growing indoors is that you’re improving the growth rate of your plants. This is mostly because hydroponics provides your plants with more oxygen in their growth phase, which again improves root growth.
Plants that tend to have a lot of oxygen in their root area can absorb nutrients much faster than when they’re placed in soil conditions. To make things better, in a hydroponic system nutrients will be mixed with water which will be sent directly to the roots at a much faster rate. On the other hand, plants grown in soil will take some time until the same nutrients reach their roots.
Another great benefit is that users can control the hydroponic nutrients as well as the amount of each nutrient. This can’t be done within the soil as it is already rich with all sorts of nutrients that can’t be controlled. The little packets of nutrients that you get with most models of hydroponic systems are already filled with everything that you need for your plants.
The ability to control nutrients is a really great thing when growing, too little or too much of some nutrient type will always lead to a deficiency which will ruin your crops. But since you can control the exact amount of each nutrient, there is nothing to worry about since correcting these deficiencies is cheap, quick, and easy. You can also discover these deficiencies a lot faster and better compared to detecting them in the soil.
One of the most important benefits of indoor growing with hydroponic systems is that you can control every single aspect of your growing environment. This ranges from pests and fungi to even diseases when you think about it, it’s like you’re playing the role of God. The last benefit and advantage of growing plants in water compared to the soil are that it is just much more entertaining to do it.
You can grow plants indoors and have a garden of your own in your home without having to step outside and get yourself dirty with all the dirt. Apart from that, it’s not just that you’re growing your plants at a more efficient rate, you’re also cleaning the air in your own home from a large range of toxins, this way you can combat the “sick building syndrome”.
Are These Complete Kits, Do You Need Anything Else?
The fun in buying hydroponic systems is that once you pay for the model you decided on, you’re getting absolutely everything. This, of course, can’t be said for all models as some just tend to send you the bare bones, but in some premium quality models you can expect to get everything, some much-needed nutrients, an air pump, and sometimes even plant growing rocks.
If you’re lucky, perhaps you will even get a manual that also shows some valuable tricks and tips, as well as some, do’s and don’ts. Once you get your hydroponic system kit, you’re only forced to set it all up, in most cases, you will see that it is kind of like setting up LEGO pieces since most models are beginner friendly. But on the other hand, you may find some advanced EAF models which aren’t really beginner friendly.
Even when it comes to maintenance, you will have an easy job. Once you set it up you will only need to fill the buckets and reservoir with water. Some models even have indicators on either the buckets or just the reservoir, these indicators usually show the amount of water there is, and sometimes they even warn you if you need to add more nutrients. But be careful with indicators, LED types that are in the blue spectrum are really good because they combat algae, other models with LED in other lighting spectrums can only allow them to further grow.
A Brief History Of Hydroponic Systems
History notes that the earliest food production in greenhouses possibly occurred during the rule of Roman Emperor Tiberius during the first century when they grew off-season cucumbers under “transparent stone”. This technology was rarely used after that time and there really isn’t any reported use during the next 1500 years.
When the 17th century started, a lot of techniques were reportedly created that helped protect horticultural crops against the cold. Some of these devices included bell jars, cold frames, and glass lanterns. A hundred years later, the first glass house was built with the help of glass on one side which served as a sloping roof, later on, glass was placed on both sides.
Greenhouse production was at that time only for the rich and privileged, meant as a tool that helped people get tasty and healthy vegetables during all of the seasons. But greenhouse production wasn’t fully established until the creation of polyethylene. 1948 was the year when the first polyethylene greenhouse cover was used. Professor Emery Myers at the University of Kentucky used it because the glass was more expensive and less durable.
But the development of hydroponics was not as rapid as it should be. There was a great interest in it during the 1920s in the US, but because of various difficulties, people didn’t see it as valuable or as efficient as using soil. After a period of about 20 years, the interest in hydroponics was renewed as the plastic was created. Now in the modern era, all of the problems that prototypes of hydroponic systems had are now removed, making it more efficient and easier to work with water instead of soil.
The interest in hydroponic systems has fallen during the 1970s when the price of oil heavily increased because it increases the cost of CEA heating and cooling as well. This has caused several bankruptcies in companies that invested in this technology and a lot of interest has decreased. But after 20 years the first interests in the best hydroponic system have been reported again.
