Best Hydroponic Systems: Top 10 Indoor Systems for Growing Weed


Over the years, the art and science of growing cannabis evolved exponentially. YAY!

Lots of research has gone into creating a standardized process for growing both medical and recreational marijuana worldwide, especially if you consider the seemingly infinite number of new strains that show up every day.

The continuous search for the best process for growing cannabis has also led to an explosion in the use of indoor systems- also called hydroponic systems. These systems have become popular because they give you complete control of your strain. You’re able to control factors such as fertilizer, soil texture, humidity, light, heat, and more.

The best hydroponic systems for marijuana not only allow you to provide your plants with all these factors but also ensure you develop some of the best strains on the market. These systems are essential for serious growers.

There are various types of hydroponic systems, depending on your goal. For example, commercial growers love the nutrient film technique, which uses watertight channels to deliver nutrient solutions to the roots of your plants. The main objective here is to get the plants to grow as fast as possible – which is a critical goal for a commercial grower.

You can also try out the wick system, which is excellent for beginners and home growers. Another popular method is the deep water culture system. Its simplicity is its biggest draw, combined with its effectiveness.

If you are actively looking to start growing marijuana, there are lots of options from which to choose. We’ve gathered 10 of the best hydroponic systems we could find on the market and reviewed them all below. This guide aims to make it easier for you to start within the next couple of days.

What to Look for When Buying a Hydroponic System – Buyer’s Guide

Purchasing a hydroponic system for growing marijuana can be confusing, especially if it’s your first time. There are various brands, all claiming to do different things and use different hydroponic systems. To avoid getting confused, you need to know the factors you should use when trying to evaluate and decide which hydroponic system fits your requirements.

Here are some key factors to focus on when buying your hydroponic system.

Types of Hydroponics Systems

There are various types of systems depending on your expertise or your specific requirements for growing.

The Aeroponics System

An Aeroponics system consists of an air chamber – sometimes called a growth chamber – that you periodically infuse with the nutrient solution your plant needs for growth. This method requires no growing medium, such as soil. Instead, it operates simply be supporting proper aeration of the plant’s root system.

Some of these systems are basic and easy to use, while others are complex and can also use pumps and other smart control features. If you are planning to grow larger plants, then you should probably get the complex systems.

The Deep Water Culture (DWC) System

DWCs are one of, if not the most straightforward, methods for growing marijuana. Also called the “reservoir method,” this system has your plant roots suspended in oxygenated and nutrient-rich water. It has air pumps that aerate the water with oxygen, preventing the plants from drowning.

Deep Water Culture systems also generally feature the use of plastic buckets and net pods, which hold each plant inside a bucket.

The Drip System

The Drip concept is a popular hydroponic system for commercial and home growers. It works by slowly feeding a nutrient solution to the roots of the plant or directly on the grow medium. You usually can alternate the speed and frequency at which the solution drips. The measured drips ensure that the roots have a constant supply of nutrients and moisture needed for the plant’s growth.

The drip systems usually operate by reusing the nutrient solution and recirculating it through the growing medium. The method helps to prevent flooding. Constant recycling, however, comes with its issues like a change in pH levels. Monitoring the pH levels of your growing medium is a must when using a drip system. Drip systems are preferable for beginners because they are easy to install, use, and maintain.

The Ebb & Flow System

Also called the “Flood and Drain,” this hydro system is an alternating system of flooding the growing area with the nutrient solution at a specific time and then slowly drain it back into the system’s reservoir for reuse. A water pump and timer enable the process.

As most plants require some dry periods to aid root expansion, the ebb and flow system is an effective hydroponic system. The functionality is one of the primary reasons for its popularity.

The Nutrient Film Technique (NFT) System

The NFT works by supplying a continuous stream of nutrients in solution to the bare roots of your plants. A tilt channel recirculates the solution, creating a downward flow of nutrients over the roots. With the Nutrient Film Technique, you don’t need a growing medium. The plants also receive a high amount of oxygen as only the tips of their roots are infused in the nutrient solution.

The NFT system works well for starting your plant growth and specifically smaller plants. If you are looking to grow your plants fast in a limited space, then the NFT is perfect for that. You may, however, struggle if it’s a large plant.

The Wick System

Wick systems are the most straightforward and most affordable hydroponic systems you can get for growing your marijuana. You don’t need any pumps, timers, or electricity. All of it comes with a form of cloth or any other fibrous material which acts as the agent to diffuse the nutrient solution across the growing area.

With wick systems, you need a growing medium. Always pick a growing medium that drains well – vermiculite – over one that absorbs an excessive amount of nutrients, such as coconut fiber.

The AeroGarden System

These systems are mostly the product of one brand, Miracle-Gro. These systems are usually well designed and come with LED lights and smart control panels that control the light intensity and colors.

There are still debates as to whether the AeroGarden system is a unique hydro system. If you look closer, the set-up appears similar to a hybrid of the DWC and Drip hydroponic systems. However, some argue that it is more of an Aeroponics system.

Growing Site

Do you plan to grow your plants in your kitchen or garage? The space in your growing area plays a significant role in your final choice. If you plan to produce a small number of plants, then space shouldn’t be a major challenge. However, if you are growing for commercial and plan on getting a hydroponic system with a lot of pots or grow pods, you need to find a space that works.

You also need to worry about flooding and ensure you get a system that has a mechanism to prevent overflows or flooding. Floods can be an issue, especially if you are going to be using the kitchen or somewhere sensitive as your growing area. You don’t want to walk in from work someday and discover your kitchen floor has flooded and cabinets damaged.

Size of the Growing Pot or Bucket

These are usually measured in gallons and are an essential factor for the size of plants you plan to grow. Most novice growers overlook this point. Within a few weeks of fast growth, a large-sized plant will likely outgrow the bucket if it’s too small. Transferring plants to a bigger bucket can be a sensitive job, especially if you have no one around who can do it without damaging the plant or stifling its growth.

Expandability of the Grow System

The ability to expand the grow kit as your production increases or your needs change is an important attribute. Scalability matters, especially if you are a beginner who catches on quite fast. Not every system has this ability, so you need to specifically look for it when shopping for your hydroponic system.

Smart Hydroponic Systems

With the rise of artificial intelligence, growers are beginning to prefer to invest in systems that can automatically do most of the work once programmed. And so should you.

These systems simply require that you set the cadence, amount of nutrients, and oxygen the plants need. Once you have set that up, it automatically starts to do that for you, so you can focus on other more critical tasks.

Final Thoughts

By now, you should be a pro at picking the exact system that fits your specific needs. You should also note that no matter how confusing the options might be, your choice will depend on your growth goals and available space as well as whether you are growing for commercial or home use.

The good thing is that with a hydroponic setup, you have control over all the necessary elements needed to create the perfect strain of marijuana. From water to the sort of light they receive, you can go beyond just planting the seeds and hoping things turn out alright. It also has become more accessible with the rise of programmable hydro systems, so you can set up, relax, and watch your plants grow with minimal fuss and effort.
