Welcome to Grow Industry , your trusted source of knowledge and innovation in the world of Marijuana cultivation. In this guide we are going to talk about one of the hydroponic growing systems that has become a revolutionary growing technique that challenges traditional agricultural practices. Among the various systems that make up the universe of hydroponics, the Wick System emerges as an ingenious, accessible and efficient solution, ideal for both novices in gardening and experts in intensive crops. This method, which dispenses with soil and nourishes plants directly through an aqueous solution rich in minerals, not only optimizes the use of resources but also opens a new spectrum of possibilities for growing in small, controlled spaces. In this article, we will dive into the roots of the Wick System, exploring its operation, advantages, and how it can be the key to maximum results hydroponic growing.

What is the Mecha System?

The Wick System is a hydroponic growing technique that is characterized by its simplicity and effectiveness. In this system, plants feed and grow without the need for soil, using a nutrient solution that provides them with all the essential elements for their development. The wick, which gives its name to the system, is a cord or strip of absorbent material that connects the culture medium with the nutrient solution. By capillary action, this wick transports water and nutrients from a reservoir to the root zone of the plants.

This method is especially popular among those new to hydroponics due to its low cost and ease of use. It does not require complex equipment or electricity to pump the nutrient solution, making it affordable and sustainable. Additionally, the Wick System is versatile and can be deployed in various environments and scales, from small home gardens to larger commercial facilities.

The efficiency of the system lies in its ability to maintain a constant and balanced supply of water and nutrients, resulting in healthy and vigorous plant growth. At the same time, it reduces the risk of overwatering or malnutrition, common problems in traditional gardening. With the Wick System, growers can expect larger, higher quality harvests, all while minimizing environmental impact and conserving valuable resources like water and marijuana fertilizers .

Wick system components

The wick system is one of the simplest and most effective methods for hydroponic growing, especially for those who are new to this technique. The basic components of a wick system are:

• Container for the Plant : It is the place where the plant and its growing medium are located. It can be any container that is large enough to house the plant and the substrate, and that allows the insertion of the wicks.
• Growing Medium : Although the wick system does not require a specific growing medium, hydroponic substrates such as coconut fiber, perlite or vermiculite are usually used, which have good moisture retention capacity and allow adequate aeration of the roots. .
• Wick : This is the key element of the system and acts as a bridge to transport the nutrient solution from the reservoir to the plant. The wicks can be made of materials such as cotton rope, strips of fabric or nylon cords, as long as they are capable of absorbing and transporting the nutrient solution by capillarity.
• Nutrient Reservoir : It is a container that stores the nutrient solution. It should be large enough to supply plants between waterings and located below the plant container so capillary action can function properly.
• Nutrient Solution : It is a mixture of water and essential nutrients that the plant needs for its growth. The solution must be balanced and adapted to the specific needs of the marijuana plant.
• Support or Structure : Depending on the design, it may be necessary to have a structure that supports the plant containers above the nutrient reservoir.
• Cover or Lid : To prevent evaporation and algae proliferation, the reservoir is usually covered. Additionally, it helps keep the nutrient solution free of contaminants.
• Aeration System (optional) : Although not essential, some wick systems include aerators to oxygenate the nutrient solution, which can improve root health and plant growth. Choose an air pump for cultivation that suits your needs.

This system is ideal for small growers or those who want to experiment with hydroponics due to its simplicity and low cost of implementation.

Principle of Capillarity

The principle of capillarity is a physical phenomenon that allows liquids to move through porous materials or in narrow spaces without the assistance of external forces and against gravity. This effect is possible thanks to the surface tension of the liquid and the adhesion forces between the liquid and the porous material, which are stronger than the cohesive forces within the liquid.

In the context of the hydroponic wick system, capillarity is the mechanism by which the nutrient solution is absorbed by the wick and transported from the reservoir to the root zone of the plants. The wick, when in contact with the growing medium, allows the solution to disperse evenly, providing the roots with constant access to the nutrients and water necessary for their growth.

This principle is essential to the efficient operation of the wick system, as it ensures that plants can receive adequate hydration and feeding without the need for mechanical or electrical systems, greatly simplifying design and reducing operation and maintenance costs.

Assembly instructions

Setting up a wick system is a simple process that can be done even by those who are new to hydroponics. Here I provide a step-by-step guide along with some practical tips and recommendations for installation:

Step 1: Preparation of Materials

To begin building your hydroponic wick system, the first step is to gather and prepare all the necessary materials. Here is a detailed list of what you will need and how to prepare each item:

Necessary materials:

• Plant Container : Select a container that is large enough to house the plant and its root system. This can be a flower pot, bucket or any other suitable container.
• Nutrient Solution Reservoir : You will need a larger container that will act as a reservoir for the nutrient solution. This should be able to store enough solution to keep the plant hydrated between refilling periods.
• Wick : Choose an absorbent, rot-resistant material, such as cotton rope, nylon, or rock wool. Make sure it is long enough to extend from the bottom of the reservoir to the top of the growing medium.
• Hydroponic Substrate : Choose an inert growing medium that allows good aeration and moisture retention, such asperlite , vermiculite or coconut fiber .
• Hydroponic Nutrient Solution : Prepare or purchase a nutrient solution formulated for hydroponics, containing all the essential nutrients for the growth of your plants.
• Tools : Have cutting and hole-making tools on hand, such as a drill, scissors, or knife.

Preparation of Materials:

• Cleaning : Before you begin, clean all your containers and tools to avoid contamination. You can use a diluted bleach solution to disinfect them.
• Measuring and Cutting : Measure the length of the wick needed, taking into account the distance between the bottom of the reservoir and the top of the growing medium in the plant container. Cut the wick to the appropriate size.
• Drilling the Container : Using the drill or cutting tool, make a hole in the base of the plant container. This hole should be slightly smaller than the diameter of the wick so that the wick fits tightly and prevents leaks.

Practical tips:

• Avoid Transparent Materials : If your containers are transparent, consider wrapping them with opaque tape or painting them to prevent direct sunlight, which can promote algae growth in the nutrient solution.
• Stability : Make sure that both the plant container and the reservoir are stable and will not tip over easily, especially if you plan to place your system in an elevated location or on a balcony.
• Accessibility : Place the reservoir in an accessible place to facilitate refilling and maintaining the nutrient solution.

By following these steps and tips, you'll have a solid foundation to set up your wick system and begin your journey into the world of hydroponics.

Step 2: Plant Container Preparation

• Container Selection : Choose a container that is deep enough to allow for good root development. This can be a traditional pot, a plastic bucket, or any other container that fits the size of the plant you want to grow.
• Drilling for the Wick : Use a drill or sharp tool to make a hole in the bottom of the container. This hole should be slightly smaller than the diameter of the wick so that, when inserted, it fits snugly and does not allow the passage of the growing medium.
• Inserting the Wick : Pass the wick through the hole you created, making sure there is enough length both inside the container and in the nutrient reservoir. A good rule of thumb is to leave about one-third of the wick inside the container and two-thirds in the reservoir.
• Sealing the Hole : If necessary, use a waterproof sealant to secure the hole around the wick and prevent leaks. Make sure the sealant is non-toxic and safe for use in gardening.
• Checking Capillarity : Before adding the culture medium, it is a good idea to check that the wick is capable of transporting the nutrient solution by capillarity. You can do this by dipping the end of the wick into water and watching to see if the water moves upward.

Practical tips:

• Wick Stability : Make sure the wick does not move or move out of place. This is crucial to maintaining a constant supply of nutrients to the plants.
• Container Height : Consider the height of the container in relation to the reservoir. Gravity will play a role in the efficiency of capillarity, so the container must be placed appropriately above the level of the nutrient solution in the reservoir.
• Container Material : If you are using a recycled container, such as a paint bucket or food container, make sure it is clean and free of substances that may be toxic to plants.

With your plant container prepared, you are one step closer to completing your hydroponic wick system. This container will be the home of your plants throughout their life cycle, so it is important to make sure it is well prepared.

Step 3: Wick Installation

Once the plant container is prepared, the next step is to properly install the wick. This is a crucial component of the system, as it will be the conduit through which the nutrient solution will travel from the reservoir to the roots of the plant.

• Cutting the Wick : If you have not done so already, cut the wick to the necessary length. It should be long enough to reach from the bottom of the reservoir to the top of the growing medium in the plant container.
• Inserting the Wick into the Container : Pass the wick through the hole previously made in the bottom of the plant container. Leave a portion of the wick hanging on the outside, which will sink into the nutrient reservoir.
• Wick Positioning : Make sure the wick is well extended at the bottom of the container so that it can distribute the nutrient solution evenly throughout the growing medium. You can use clips or ties to keep the wick in place if necessary.
• Submerging the Wick in the Reservoir : Place the free end of the wick in the nutrient reservoir. Make sure there is enough wick submerged so that it can absorb the nutrient solution without problems.
• Function Check : Before proceeding, it is advisable to check that the wick transports the nutrient solution adequately. Dampen the wick and see if the moisture rises toward the other end. If it doesn't, you may need a different wick material or adjust the length immersed in the solution.

Practical tips:

• Wick Material : Choose a material that is known for its good liquid absorption and transport capacity. Materials such as cotton, rock wool or certain types of fabric work well.
• Pre-saturating the Wick : Before installing, completely submerge the wick in water to ensure it is completely wet. This will help start the capillary process.
• Avoid Bending the Wick : Keep the wick as straight as possible to facilitate the flow of the nutrient solution. Kinks or knots can prevent or slow down the movement of liquid.
• Proper Length : The wick does not need to be too long; just enough so that one end reaches the bottom of the reservoir and the other end is in contact with the growing medium.
• Safety : Make sure the wick is not exposed to direct sunlight or conditions that can quickly degrade it.

With the wick properly installed, you have established the vital link between the nutrient solution and your plants. This step ensures that your plants can consistently receive the nutrition they need to grow and thrive.

Step 4: Filling the Container with Culture Medium

Once the wick is installed, the next step is to prepare the plant container with the appropriate growing medium. This medium will be the physical support for the roots of the plant and will help distribute the nutrient solution that rises by capillarity through the wick.

• Selection of Growing Medium : Choose a growing medium that retains moisture and at the same time allows good aeration of the roots. Materials such as perlite, vermiculite or coconut fiber are popular options.
• Growing Medium Preparation : If you are using a growing medium that comes in compact or dry form, such as coconut fiber, you will need to hydrate or expand it according to the manufacturer's instructions before using it.
• Filling the Container : Begin filling the container with the growing medium, making sure the wick extends up and through the growing medium. It is important that the wick is in direct contact with the medium so that the nutrient solution can be efficiently transported to the roots.
• Securing the Wick : While filling the container, make sure the wick stays in place and doesn't move. It may be helpful to leave a small portion of the wick exposed on the surface to verify that it is still wet once the system is in operation.
• Light Compaction : Once the container is full, lightly press the growing medium to eliminate air pockets and ensure even contact with the wick and plant roots.

Practical tips:

• Don't Over-Compact : Avoid over-compacting the growing medium, as this can reduce aeration and hinder root growth.
• Growing Medium Level : Leave a small space between the growing medium and the top edge of the container to prevent overflow of the nutrient solution and to facilitate maintenance tasks.
• Initial Humidity : Before planting, lightly moisten the growing medium to activate capillarity and help the plant establish its roots more quickly.
• Capillarity Test : Perform a capillarity test before planting, making sure the growing medium can absorb the nutrient solution through the wick.

With the container now filled and the growing medium in place, your wick system is almost ready to receive the plant. This step is essential to ensure that the plant's roots will have the right environment for healthy and vigorous growth.

Step 5: Preparation of the Nutrient Reservoir

The nutrient reservoir is where the solution that will feed the plants through the wick system is stored. Here I explain how to prepare it:

• Reservoir Selection : Choose a container that is large enough to hold the nutrient solution needed for your plants. This should be larger than the plant container and should be located so that the wick can absorb the solution without problems.
• Cleaning the Reservoir : Before adding the nutrient solution, make sure the reservoir is clean and free of debris. Wash it with water and, if necessary, use a non-toxic disinfectant solution.
• Preparation of Nutrient Solution : Mix the nutrient solution according to the manufacturer's instructions or your personalized recipe. Make sure the nutrients are completely dissolved in the water.
• Filling the Reservoir : Pour the nutrient solution into the reservoir. The amount will depend on the size of your system and the number of plants you are growing.
• Reservoir Placement : Locate the reservoir in an accessible location to facilitate maintenance. It should be located so that the wick can transport the nutrient solution by capillarity to the plant container.
• Control of the Nutrient Solution : It is important to periodically monitor the pH and electrical conductivity (EC) of the solution to ensure that it remains within the appropriate ranges for your plants.

Practical tips:

• Avoid Direct Light : If possible, place the reservoir in a place where it does not receive direct light to prevent algae growth.
• Reservoir Cover : Use a lid or cover for the reservoir to reduce evaporation and prevent the entry of contaminants and algae growth.
• Easy Access for Refills : Make sure the reservoir is easy to refill and that you can access it to adjust the nutrient solution when necessary.
• Regular Monitoring : Establish a routine to check the level of the nutrient solution and refill it to ensure plants have a constant supply.
• Optional Aeration : Although not essential, some growers choose to add an aeration system to the reservoir to oxygenate the nutrient solution, which can benefit root health and plant growth.

With your nutrient reservoir ready and nutrient solution prepared, your wick system is almost complete. This step ensures that your plants will have a constant supply of the nutrients necessary for their development.

Step 6: Planting

Now that you have the wick system ready, the next step is to plant your crops. Here I explain how to do it:

• Plant Selection : Choose the plants you want to grow. Make sure they are suitable for the hydroponic system and have growing requirements compatible with the environment you can provide.
• Preparation of Marijuana Seedlings or Seeds : If you are going to start with seeds, you must germinate them first. If you use seedlings, make sure they are healthy and free of diseases or pests.
• Transplanting the Seedlings : Carefully place the seedlings in the growing medium inside the plant container. If you are using seeds, sow them according to the specific directions for each type of plant.
• Growing Medium Adjustment : Make sure the growing medium holds the plants firmly in place and that the roots are in direct contact with the wick for optimal absorption of the nutrient solution.
• Initial Watering : Lightly water the seedlings or seeds with the nutrient solution to help establish initial contact between the roots and the growing medium.
• Plant Container Placement : Position the plant container so that the wick hangs into the nutrient reservoir. Make sure the wick is well submerged in the nutrient solution.

Practical tips:

• Planting Depth : If you plant seeds, do not plant them too deep. A general rule of thumb is to plant them at a depth of twice the diameter of the seed.
• Plant Spacing : Give each plant enough room to grow. Overcrowding can lead to disease problems and competition for nutrients.
• Labeling : If you plant different types of plants, label them so you can track their progress and specific care.
• Post-Planting Monitoring : Observe plants regularly to ensure the wick is supplying sufficient nutrient solution. Signs that plants are not getting enough water include wilting or drying leaves.
• Adjustments : Be prepared to make adjustments to wick position or nutrient solution concentration based on plant response.

Wick System Maintenance:

Maintenance of a wick system is relatively simple, but essential to ensure the good condition of the plants and the efficiency of the system. Here are some key steps for maintenance:

• Wick Check : It is important to periodically check that the wick is not clogged and that it is transporting the nutrient solution efficiently. If the wick dries out or becomes clogged, the plants will not receive the necessary nutrients.
• Nutrient Solution Control : Nutrient solution should be monitored and replaced regularly to maintain proper pH and electrical conductivity (EC) levels. This ensures that plants are receiving nutrients in the correct proportions.
• System Cleaning : From time to time, it is advisable to clean the plant container and nutrient reservoir to prevent the accumulation of salts and the proliferation of algae and pathogens.
