How to Use Crop Cycling for Cannabis Cultivation

How to use crop cycling for cannabis cultivation

Crop rotation is a farming practice that helps preserve soil health, optimize nutrients in the soil, and combat pests and diseases. In addition, crop rotation can improve the structure of the soil as different crops grow at different depths.

Cannabis plants are photosensitive and need a certain ratio of light to dark hours throughout the vegetative stage. This light schedule is critical for optimum growth.


Soil is a key ingredient in any successful cannabis grow. It provides nutrients, moisture, and a home for microorganisms that facilitate healthy growth and development of your plants. There are many different types of soils and each one has different characteristics that can impact how well your plant grows.

The best soils for marijuana cultivation are the ones that provide the most nutrients and have good drainage. These include sandy soil, silty soil, loamy soil, and clay soil.

Once you have decided on your ideal soil, it’s time to get started! Begin by mixing your organic ingredients together, such as compost and worm castings. This will allow you to create a custom soil blend that meets all of your cannabis growing needs.

Adding perlite to your soil mix will increase its aeration and help your plants thrive. It also adds structure and helps reduce the chance of mold and mildew forming.

Another popular ingredient in a potting mix is 50% vermiculite, which acts like a sponge and holds up to four times its own weight in water. It can also attract positively charged ions and prevent them from leaching away from your soil.

For the best possible outcome, it’s important to choose a soil that can support your cannabis plants for their entire life cycle. This means choosing a soil that’s full of beneficial bacteria and fungi, as well as a good balance of macronutrients and micronutrients.

A good soil mix will contain a combination of high-quality peat, compost, and worm castings. Having all of these components in your mix will ensure that the soil has an optimal pH and a high concentration of the essential nutrients for your cannabis plants to thrive.

It’s also a good idea to have a soil mix that is fully amended with living bacteria and fungi. These living organisms will interact with your cannabis plants’ root systems to help them thrive and improve their immune system. They can also assist in converting complex sugars into readily available nutrients for your plant.

Finally, it’s important to note that your soil should be aerated regularly to keep the roots of your cannabis plants from overheating and becoming susceptible to diseases. This can be done through the use of air pots, smart pots, or even dry straw.


Crop cycling is a great way to increase the yield of your cannabis crop. It involves rotating between vegetative and flowering growth stages while maintaining a consistent growing cycle. This can help you get the most out of a small indoor grow space and will make it easier to produce a consistent harvest.

The key to successful cultivation is to ensure that your cannabis plants receive the proper amount of light at every stage of the growth cycle. This will allow them to thrive and produce a high quality, nutritious crop.

To start with, cultivators need to know the specific wavelengths of light that are needed by their plants throughout different growth stages. This is important because all wavelengths serve a particular morphological, developmental and chemical action in the plant.

In the seedling/vegetative phase, cultivators prefer to use blue spectrum LED lights that mimic what the plant would receive naturally from the sun. This helps the plant to adjust to the new conditions and to produce strong roots.

Once the plant has acclimated to the new lighting regime, it can then begin growing flowers. It requires a high DLI (day light integral) to successfully achieve this, so choosing a grow light with an output that can provide this level of light intensity is crucial for success in the flowering stage.

Another crucial aspect to consider is the spectral power distribution of your grow lights. This is a factor that determines the color and intensity of your lighting.

During the early vegetative phase, cultivators should avoid using red- and far-red light as these can cause damage to the leaves and stems of the plant. A full-spectrum LED grow light will contain all of the colors that a cannabis plant needs to thrive.

In addition, LED light systems are typically more powerful than MH and HPS lamps. This is because they have a higher PAR value and produce a more even spread of light.

However, LEDs do consume a lot of energy. This can quickly add up on your electricity bill, especially if you have several lights in the same room.

Temperature is a major factor in cannabis cultivation, and it is essential to maintain the right temperature for your cannabis plants throughout their growth cycle. This is because it can affect plant development, yield, quality, terpene degradation, and plant health.

The optimal temperature for a cannabis plant to grow is between 68-77 degrees Fahrenheit. If the room temperature drops below this, the plant will not grow as fast or may even stop growing altogether.

This is especially important in the vegetative stage, when stem and leaf production are crucial to a healthy crop. The best way to get the optimal temperature is to set up a thermostat and control it carefully.

It is also a good idea to buy an accurate thermometer and hygrometer so you can keep an eye on both the temperature and humidity of your growing area. This will ensure you don’t have any problems during the different stages of your plants growth cycles.

A digital thermometer will help you check the temperature while a hygrometer will help you check the humidity levels as well. Having these tools on hand will help you make sure that your cannabis plants are not getting too much or too little of both, and that you can easily maintain the perfect temperature and relative humidity for each stage of their growth cycles.

In terms of regulating the temperature for your cannabis plants, it is also very important to remember that the ideal night time temperature is around 10 deg F lower than the daytime. This will allow the plant to have a resting period at night, which is essential for them during flowering, when they need to conserve energy for their buds.

During the flowering stage, a temperature of 65-75degF is also recommended to maximize bud formation. Having the correct temperature and a proper light exposure during this stage is very important for the plant to mature properly.

Achieving consistency and repeatability in the crop cycle is key to commercial profitability, which is why many cultivators use crop cycling. This involves planning a series of grow cycles based on each strain’s needs and growth rate. It’s an excellent way to increase annual yields, but it is also highly dependent on ensuring that all of the other aspects of your grow room are working correctly.

Water is an essential element in cannabis cultivation, enabling plants to thrive and produce their best buds. It also helps regulate nutrient levels, keep the plant’s root system healthy, and ensure proper temperature regulation.

There are many ways to use water in the growing process, and it’s important to understand how to manage it properly. This includes determining the best water source for your crop, testing it, reducing water runoff, and using smart irrigation systems to maximize water efficiency.

Choosing the right water source is crucial for a successful cannabis harvest, as it can affect the quality and potency of your final product. Whether you’re growing marijuana hydroponically or in soil, it’s important to check the water’s pH and temperature before feeding it to your plants.

In addition to the water’s pH, a plant’s roots are also impacted by its temperature. Too warm or too cold water can damage a plant’s root system, making it less able to absorb necessary nutrients.

Temperature also affects the way in which water can be absorbed by the plant’s leaves and stems. When the water is too cold, it can freeze, and when the water is too hot, it can scald the plant’s leaves or cause the stem to break.

For hydroponic cannabis cultivation, it’s best to use water with a pH of 5.5-6.5 and temperatures around 60 degrees Fahrenheit. This is a good balance to maintain, as the plants are able to soak up more nutrients than they would in water with an acidic pH.

Similarly, it’s best to avoid watering plants with water that is too diluted or has too much mineral content. These can make a plant sick and lead to reduced growth rates or even death.

It’s also a good idea to test the water before and after you feed it to your cannabis crops. This will allow you to determine the pH level of the water, which will let you know if it’s too rich or too acidic for your plants.

Keeping a close eye on your water usage can help you save money, improve your facility’s water efficiency, and comply with state and municipal regulations. In addition, using drip irrigation systems and capturing condensate from HVACD equipment can also significantly reduce your water usage.
