Moreover, all through the article, our focus will also be on growing marijuana using this method of growing plants. 

The marijuana plant has witnessed several innovations in the way it is grown. From being an ancient herb that was used by early civilizations for medicinal and recreational purposes, it has grown into the world’s most controversial plant. While there has been quite the resurgence in the medicinal use of marijuana over the years, growing weed still remains quite a controversial subject. Growing weed using hydroponic systems is another angle that we will explore. Marijuana which traditionally used to grow outdoors in nature was soon cultivated by humans and is today grown with extreme care so that each plant offers maximum possible output. Hydroponic growth is not radically new but is indeed quite the innovation in growing marijuana. Let us take a detailed look at it –

What is Hydroponics?

Made out of the Greek words Hydros and Ponos, the word Hydroponics basically means the labor of water. And that’s exactly what this method employs – instead of using soil as the medium to carry the nutrients, it is the water which directly provides them to the plants. Growing plant without soil might sound strange to those who are new to the world of gardening but hydroponic growth is all about providing nutrient-rich water directly to the roots instead of providing it to the soil from where the plants can seek it. 

In case of a hydroponic growth, there are different setups which make use of elaborate systems in which water reaches the plants directly. Plants usually grow in something like peat moss, coco coir, rockwool cubes, etc. which hold it together but don’t really act as a medium of growth which is purely water in this case. Let us now take a detailed look at the vertical hydroponic system and try and understand how it functions – 

What is a Vertical Hydroponic System?

A vertical hydroponic system basically comprises towers with multiple water outlets, along with a pump at the bottom which helps the water flow up, reach all the plants, and then flow back into the reservoir from where it can be reused. This is nutrient-rich water reaches the roots directly and helps the plants get access to it quicker than they would in a soil-based medium. Furthermore, since this is a vertically stacked medium you can grow more plants in a smaller area. They look good, save space, as well as reuse water and are hence quite a great option for growers looking forward to growing their marijuana plants indoors.

However, while indoor growth is one way they can be used, they can also be placed outside. There are larger versions of these vertical hydroponic systems which are basically garden planters which support a large number of plants but utilize the same fundamental mechanism. Let us now take a look at the five best options that we have when it comes to buying vertical hydroponic systems to grow marijuana.

Buyer’s Guide: Factors to Consider While Buying a Vertical Hydroponic System

Now that you know which are the best options that you have when it comes to buying these vertical hydroponic systems online, here’s a look at some of the factors that you must consider before you purchase them. You might want to use this list as a checklist of sorts and judge each of the above systems against them. 

  • Material – You need to know what material your planter is made out of – this is for multiple reasons. First off, you need to make sure that you are using a durable and high quality material that will last you for at least a few seasons. Moreover, you also need to ensure that you are not getting something which is toxic and might end up damaging your plants! One of the best ways to ensure that you are staying safe from these problems is by getting hold of planters which are made out of BPA-free and UV stabilised material.
  • Size – The size of your planters is very important. One of the biggest benefits of vertical hydroponic gardening is that it allows you to grow more in lesser space. Make sure that this objective is being achieved when you buy the setup of your choice! The best planters occupy the least space yet allow you to grow the most number of plants. Size should also be seen in relation to balance. Your setup needs to have a solid base which will not topple over due to the weight.
  • Number of PlantsHow many plants can you grow in your planter? This is one of the most important questions that you need to ask yourself. Most of them allow you to grow at least 20 plants – while there are some bigger ones where you can grow an even larger number of plants. Make sure you know of this statistic before you buy the vertical hydroponic system of your choice.
  • Ease of UseThis is also something that growers must keep in mind before buying the planter of their choice. It should be easy to operate. Especially if you are a first-time hydroponic grower get a very simple setup so that you do not end up getting confused and do not over-water or under-water your plants!
  • DesignLast but not the least it should go with the aesthetic appeal of the area you plan to keep it at! The planter must not stick out like a sore thumb and should blend in well with where it has been kept at!

Best Tips for Growing Weed in a Hydroponic Setup

Here are some of the best tips and tricks that you must keep in mind while growing marijuana, or any other plant for that matter, in a vertical hydroponic system.

  • The first thing that you need to take care of is the temperature at which you are growing your plants. The temperature needs to be ‘ideal’. It should not be too hot and it should not be too cold either. Usually marijuana plants grow the best when temperature conditions are somewhere between 18 to 25 degrees Celsius.
  • Apart from adjusting the right temperature you also need to keep the humidity levels right. Normally when you grow a marijuana plant in soil you’ll need a higher humidity in the early stages so that the roots aren’t strained, but since this is a hydroponic setup the levels of humidity can be low in both the phases – the growth phase as well as the bloomin phase.
  • Lighting is the third and perhaps the most critical thing that you must take care of. While most people using planters prefer growing their plants in natural light, there also need to be some extra sources of lighting because plants generally need about 22 to 16 hours of light during the period of being a plantling to pre-flowering – which is the bulk of their lifetime. Make sure you’re providing full-spectrum lighting for the best results. Modern-day growers prefer using LED lights.
  • While the whole idea behind growing plants in a vertical hydroponic system is to save on space, one must make sure to not get too carried away and cramp up the system. There needs to be appropriate spacing between the towers so that their plants don’t intertwine with each other and that there is sufficient air-flow between them as well. 
  • One final thing that you need to take care of while growing in a hydroponic setup is that you are providing the right kind of nutrients and in the right amount. The latter is equally important as the former. Providing less nutrients might lead to your plants not being able to bloom to their maximum potential while providing more nutrients might result in nutrient burns! This is why you need a basic experience with growing weed before you progress to growing them hydroponically. 

Pros and Cons of Hydroponics

As we approach towards the end of this article, we hope that you have gained quite the insight about growing your marijuana plants in a vertical hydroponic system. Here’s one last look at the advantages and disadvantages of hydroponics for growing plants such as marijuana:

Lastly, before we proceed into the Frequently Asked Questions (FAQs), let us take one final look at whether it is worth your time, money and effort to invest in a vertical hydroponics system for growing marijuana:

Is Vertical Hydroponics Worth It?

Vertical hydroponic systems are totally worth it if you are a grower who is willing to experiment and try out something new! They are also quite a great option for those growers who want to experience hydroponic gardening. However, one must keep in mind that in order to attain proper hydroponic growth you need to be familiar with the basics and know the fundamentals of growing fully well. We don’t really advice this for beginners. This is also a great option for those growers who live in a place where there is a perpetual shortage of water as the same water can be reused in the system for multiple days. Apart from marijuana growers, people who like to grow ornamental flowers or small kitchen-variety plants should also try this out, especially when you combine it with things such as a grow light, the results are even more effective.

2. Are there any drawbacks of hydroponic systems?

As such ther are no “drawbacks” of growing weed this way, but some traditional soil-based growers might not want to move to this due to it being a radically different method.
