Steps In Understanding Hemp Plants Spacing

Small-scale hemp seedlings can be deceiving to look at if ever be planted in a vast area of the field. It appears to be unproductive, but actually, they can grow into bountiful hemp plants. Here are the basic steps to consider to better understand hemp plant spacing.


#1 Knowing the importance of plant spacing

How much space do you need between hemp plants? The hemp plants need adequate spacing for healthier growth and successful crop production.  Let’s further discuss some of the reasons why you should consider proper plant spacing:


1. Absorption of nutrients

Planting hemp seeds or plants with their adequate spacing enables them to have an efficient time absorbing and digesting their nutrients. If there is no issue concerning their growth, they will thrive and give farmers the reward of abundant crop production for harvest.


2. Plant monitoring

For us, spaces give us a faster time finding or searching for something because there is no barrier along the way. Same as through with the plants, it links to help farmers monitor their hemp plants. Unnecessary weeds can be detected and removed easily.

Fast-spreading fungus like mildew can contaminate plants by traveling from other leaves if they’re too close. But if plants will have spaces, they not spread rapidly, and air could circulate well.


#2 Determining the hemp spaces

Hemp plant also varies in types. The two types of hemp plants are industrial hemp and cannabinoid hemp (CBD). Here are the proper hemp spaces required according to the type of the plant:


1. Industrial hemp

Industrial hemp is not too distant in terms of spacing. They are required to have four to six inches in your garden or greenhouse. The fibrous stalks of hemp are the reason why industrial help has minimal spacing.

Industrial hemp in greenhouses is not required for blooming flowers. They are just intended to occupy the large spaces given to them in industrial land. But the required spacing for them is still important to follow.


2. Cannabinoid hemp

In cannabinoid hemp, the usual requirement of their spacing ranges from four to six feet by distance next to each other. CBD hemp plants are flowering hemp and need a larger space to thrive in.

Space enables them to acquire an adequate amount of lighting, converted into energy necessary to produce luxuriant, cannabinoid-rich flowers.


#3 Considering the types of environment

Primarily, hemp plants have three growing environments: greenhouse, indoor, and field.

But, different environments of hemp plants also have their pros and cons. Hemp growing farmers consider the type of environment they desired for their hemp to grow.


1. Greenhouse

Planting hemp in greenhouses is way more controllable and manageable compared to the field. A greenhouse is secured and is protected from destructive pests. It is also a money-saving idea and can have a lesser ecological footprint.

In connection with greenhouse-grown hemp, you must acquire a license in growing your greenhouse hemp. You can get it through your local hemp regulation offices.


2. Indoor

Some farmers are converting their warehouses for growing their indoor-grown hemp. The advantage of indoor planting of hemp is the superior control of its environmental condition.  It is much secured from the attacks of pests.

Furthermore, farmers can manage proper lighting control. Allowing hemp to grow in a denser ambiance will enable to produce potent production of flowers.

Though, it could be a challenge of start-up cost at first because of a large set-up. The allocation involves reconstruction of the area and accommodation of the planting materials. All in all, it requires effort and a long time.


3. Field

Filed-grown hemp is the traditional way of planting among farmers for thousands of years. It is a natural option among farmers with spacious agricultural land and into the concept of agricultural production.

The beneficial impacts of growing hemp in fields are very evident. They could acquire adequate light and enough space. The full spectrum of light colors contained by the presence of UV light is salient in the blooming period of hemp.

Although outdoor plants are susceptible to soil contamination, hemp is a versatile kind of plants. They have phytoremediation qualities as a defense for the occurrence of contaminants and stabilize their growth.

If there are pros, also expect the cons. If the hemp is already planted outdoors, it will be left there under whimsical weather. Farmers must track the condition of the weather first. Field-grown hemp can encounter unwieldy security issues and restrictions given by its large location.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
