What is hydroponics growing?

The beginners usually have a problem understanding how to grow weed hydroponically step by step. The hydroponic system of growing weed refers to cultivating and harvesting it in a water-based and nutrient-rich solution. In this case, soil isn’t used.

The roots of the weed plant are kept intact using different inert mediums such as perlite, clay pellets, moss, vermiculite or Rockwool. In this procedure, the roots of the plant come in direct contact with a nutrient solution. This direct contact ensures proper growth.

Advantages of hydroponics weed growing for beginners

There are a lot of benefits you acquire by hydroponics growing of the weed. The benefits of growing hydroponically include the following:

Fast growth

Growing hydroponic weeds ensures that the plants grow faster than with traditional methods. This is because they come in direct contact with the nutrients and can absorb more of it. Most of the experts have said that weed & cannabis plants grow 20% more quickly in hydroponics rather than in soil.

Large quantity

Growing weed hydroponically allows you to harvest in large quantities. Even in this case, the yields are about 20-25% more than that of the soil growth. You will need less space for each plant to grow.

No weeds

Gardeners usually have a tough time cleaning up the mess caused by the overgrowth of weeds. You need to keep a check on the growth and pull out when it is in the soil. Though, this is not the case with hydroponics growing. You can’t get overgrowth of weeds in the soil because there is no soil.

In the first case, the solution needs to be sprayed using a nozzle. Secondly, the pond fogger method needs to be used. In this method, PTFE Teflon coated disc may surround the plant.

Wicking

It is not only a comfortable but a cheap system as well. In this case, the wicking material like cotton needs to be covered or encircled with the growing medium on one side and the wick placed in nutrient on the other.

You may use a medium such as perlite or vermiculite. In this case, do not use mediums such as peat moss because they absorb excess nutrients which can be harmful to the plant.

Nutrient Film Technique

This procedure is also referred to as NFT. This is where there is a regular flow of nutrient solution. This flow happens above the roots of the plants. The system is a little tilted to ensure proper flow towards gravity.

It is very convenient because the roots get to absorb most of the oxygen from the air. They, however, absorb it from nutrient solution too. The tip of the root comes in direct contact to the nutrient solution. Thus, this increases the rate of growth for the plants.

Drip System

This process of indoor hydroponics is straightforward and convenient. However, you will need to feed nutrients slowly to the plants.

You can use any medium that drains off faster. However, it is more convenient to use a slow draining medium. One of the significant drawbacks is that it the drip system can get clogged easily and blocks the dripping nutrients.

Ebb & Flow

This method of growing hydroponics weed for beginners is also referred to as the drain and flow method. It is the perfect method for plants that dry off quickly. Various weed plants that grow during the dry period and the root system are still able to retain the moisture.

How to grow weed hydroponically step by step?

In this case of growing hydroponic, you will need to set up a system. The easiest indoor hydroponics method is the deep water culture method. It is easy and needs the least amount of materials. Moreover, it is the best method for growing weed hydroponically for beginners.

Begin by filling up the reservoir with the required nutrient solution. Then suspend the root of the plant to the solution. This will allow the root to soak the nutrients steadily and continuously. Moreover, it will also offer a continuous supply of oxygen, water, and nutrients.

Go on adding the oxygen to water. One of the best ways into which you can add oxygen to the water is with an air pump. You can also use the air stone pump to bring about bubbles. This will prevent your plants from drowning. This procedure can be easily set up and requires deficient maintenance.

How to germinate the seeds?

If you are considering to grow hydroponics weeds on a large-scale basis, you will need to set up a garden inside a grow room. You can usually purchase the marijuana seeds online. The price of these seeds typically varies depending on the strain you choose. Thus, you will require to be very careful with the strain. You should set up the hydroponics garden and check if everything is working. You can then take your next step of hydroponics weed growing for beginners by germinating the seeds. If you have bought clones instead of seeds, you should not consider sprouting them.

There are a lot of mediums available in the market for the growth of the plant. Since you’re not using the soil, you will be in utter need of the medium as the substitute. One of the most used media include Rockwool. Although it does not offer nutrition, it can be a great support.

Place the seed in the midst of the nutrient solution and then submerge about 70% of the cube in water. Allow it to settle and germinate. If you notice growth in the seeds, you can take it out with the roots facing downwards, and place it in the nutrient medium to ensure growth.

Vegetative phase

Once the seed germination process is over, the marijuana will begin to develop to the first stage of the vegetative phase. In this stage, the plant gets long roots and grows leaves that assure photosynthesis. It is preparing itself for the budding phase.

In this phase, you need to provide light for about 18-24 hours. For this purpose, you can choose to put up the lamp 20 inches above the plant to prevent drying. Moreover, you can keep on decreasing the distance depending on the height you like and gives the best results.

The vegetative phase is best for indoor hydroponics and can last for about 2-4 weeks. However, the time may vary depending on the strain you choose. The growth rate of the plant depends on how much energy is produced by the plant. Bigger leaves ensure a better rate of photosynthesis that simultaneously allow faster growth.

Most of the plants grow about 6 inches a day if the conditions of the room are ideal. However, you will have to maintain the optimal conditions of the hydroponic garden too.

Thus, you need to ensure to maintain the ideal condition of your room and garden to allow proper growth. Make sure enough light is reaching the leaves.

Light phase

Most of the experts have often stated the use of blue light to prevent stretching. If the plant does not get sufficient blue light, there will be massive space between the branches which also leads to a weakening of the plants. HPS lights provide a lot of blue light. However, the most popular ones that are used during the light phase include the MH lamps and LED lamps. Most of the growers use CFL lamps these days for better results.

If you’re providing light for less than 24 hours, you should make sure that you work with a timer. The amount of light needed for growth depends on various factors so you can check with them. Some of the factors that affect the light include temperature, the distance between lamp and plant, the maturity of the plant, the strength of the lamp and more.

Grow room condition

You should check for the temperature of the room before allowing germination and growth. If this factor isn’t checked upon properly, it can lead to stunted growth of the plant. Usually, the ideal temperature is recommended to be 70-83 degrees Fahrenheit. Also, a higher concentration of CO2 is required.

For the dark period, it is necessary to check with the low temperature. For the growth period, experts often suggest using 72-77 degrees. You can use a thermometer to measure the temperature and humidity in your grow room.

The marijuana plants require carbon dioxide as well as light during the growing hydroponics phase. It is for this purpose that you need to ventilate your grow room. If you’re growing them in a room, you should ensure to put up the exit as well as intake vents. During the flowering stage, you can put up the oscillating fans for convenience.

How and when to switch to flowering?

The time for switching to flowering usually varies from plant to plant and person to person. While some people prefer switching to flowering from buds within two weeks, some seem to wait for 3-4 months. The period for switching to the flowering stage is entirely a matter of personal choice.

One key point to keep in mind is that the plants will continue to grow even when you have turned to the flowering phase.

Harvesting, curing and storing marijuana without the smell

This is one of the hardest parts about how to grow weed hydroponically step by step. By this time, your plants have grown enough and have big buds. You will get the result in this stage and also how is the quality of the bud. You need to know the proper timing, curing and drying to get the best results.

When is the best time to harvest?

The time you harvest the buds has an impact on the active substance in the weed. The primary active components of the buds include THC and CBD. If you harvest the plants too early, it can lead to lower concentrations. However, if you accumulate it for long, it can lead to damage in the substances. Either way, you need to be a little careful about the harvest time since it has an impact on the weed quality. The best time to do this really depends on your plants. There is not a fixed answer to this question.

How to dry marijuana?

As far as flavors and smell are concerned, marijuana has diverse categories. It has different flowers, and each has over 100 flavorful flavonoids. The taste also depends on the terpenes.

Drying the weed is one essential steps after germinating and growing. However, if the weed isn’t dryed, the molecules in it will get destroyed. The result would be a tasteless weed and a disgusting smell. You have to dry your weed slowly to ensure better flavor.

Next, you should ensure that there is enough room for air circulation to ensure proper preservation. This will keep away all the fungus and molds, which have a negative impact on the buds.

You should take care of the curing process for hydroponics growing. Usually, the buds need to be cured for 2-4 weeks. This improves terpenes and enhances the taste of the buds. Ensure that the drying area is dark and ventilated.

If you apply excessive heat for drying, it may have a negative impact on the buds. Thus, you should ensure to dry it at the average room temperature.

How to cure marijuana?

Before you begin curing the marijuana, you need to trim it properly. For this purpose, you may either use a bud trimmer machine or extremely sharp scissors. Make sure to get rid of the extra leaves on the buds. This helps to improve the look. However, the cutout leaves contain trichomes, which can be beneficial for the smoking process.

After trimming, separate the buds and the stems. Next, store the stems in an airtight container. A plastic bag is considerable, but you might want to store everything in an airtight container.

In the initial weeks, you should leave some space out so fresh air enters the container. You may do this for about 15 minutes. This will help the existent moisture to evaporate.

You can also try to smoke it. However, there will be a difference in the curing rate due to the strain. Nonetheless, if you have followed all the methods correctly, your indoor hydroponics setup will work and cannabis will grow with proper efficiency.
