You should plant your hemp plants in an enclosed, locked space that shouldn’t be publicly viewed. For example, you can’t plant hemp in your backyard or outdoor garden, even if it’s enclosed in a fence.

If you have minors living with you (under the age of 21), you need to put your hemp in a separate locked space where they won’t be able to access the plants. If you don’t live with a minor, your hemp plants still need to be inaccessible.

While Colorado’s high altitude and thin air may be a problem for other plants, hemp can grow well in this environment. Even though it’s great to grow hemp outdoors, you can use a greenhouse to create an ideal indoor environment.

Make sure to till the soil before planting your seeds and prepare a shallow bed. It’s better to sow your hemp seeds directly into the soil rather than starting in pots. The best time to plant hemp is when the last frost has passed and the soil temperatures are at least 50 degrees F. In this way, your seeds will germinate quickly and grow into tall, healthy hemp plants.

You want to space out your seeds well. Four inches is the general rule of thumb for hemp, but this ultimately depends on your space and desired yield. Place the seeds in soil depth of ½ or ¾ inch.

When it comes to tending your crops, make sure to effectively irrigate your hemp seeds, especially during the first month and a half. Hemp plants are usually tolerant of drought, but seedlings are more sensitive to heat and dryness in the first few weeks.


How Often Can You Harvest Hemp?

You can harvest mature heads of hemp plants after 90 to 100 days. As you grow your hemp plants, you can start to see the seed heads mature from bottom to top. It usually takes around 100 to 120 days until your hemp plants to be fully ready for harvest.


How Much Profit Can You Make by Growing Hemp?

According to a study from Cornell University, you can make around $130 to $730 for every acre of hemp plants. With a single hemp plant, you can make a profit from its roots, stalks, leaves, seeds, and flowers.

Growing organic hemp opens up a wide range of products you can produce – from food and health and beauty products to industrial textiles, building materials, industrial products, consumer textiles, and paper.

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.
