First of all, hydroponics is a well-known method for indoor soilless growing. Moreover, this method consists of soaking the roots in a nutrient and oxygenated solution. In other words, it means that we do not use soil and the cannabis plants grow in an inert and sterile growing medium.
Secondly, the hydroponic method provides nutrients to the oxygenated water container. In other words, the roots of the cannabis plant grow faster and bigger. Therefore, a hydroponic cannabis crop can exhibit a growth rate 30% to 50% faster than that of a soil-grown cannabis plant.
What are the benefits of hydroponic growing?
Firstly, the ease of supplying nutrients to our cannabis crop. Secondly, the faster growth rate. In addition, there are other advantages why many growers are being encouraged to grow with hydroponics.
Hydroponic systems can use 20 times less water than traditional soil cultivation. In addition, the water in this method of cultivation is reused. In other words, in some regions of the world, rainwater is crucial to sustain your crops.
First of all, 20% less cultivation space is saved compared to soil cultivation. In addition, our growing area is kept cleaner and without the need for as many pesticides.
First of all, if you have a growing area intended exclusively for cannabis you can use it all year round. In addition, it is ideal for growing autoflowering seeds.
Many cannabis grow nurseries in the United States, charge their customers more money to grow hydroponically. In other words, hydroponically grown cannabis plants tend to have larger and bulkier flowers.
What are the drawbacks of hydroponic growing?
First of all, this method of growing cannabis is more expensive than growing in soil. Also, if it’s your first time you have to shell out a lot of money.
Secondly, you have to have an extensive planning of all the necessary materials, even a power outage in your house can mean the loss of your crop. In other words, a small generator should be on hand.
Thirdly, this method involves constant dedication. In other words, if your hydroponics system gets sick, the entire cannabis harvest can be lost. Also, harmful microorganisms also thrive in humid environments.
Finally, we already have the benefits and drawbacks of hydroponic growing. However, if we are going to grow our cannabis seeds in hydroponics, we have to be clear about three points:
1. PH and PPM
First, it is important to constantly measure the PH and PPM levels every day. In other words, the PH meter helps us to know how much alkaline or acidic our water is. In addition, the EC meter is used to measure the particles per million.
Secondly, PH levels should be around 5.5 and 6.2. Also, remember to maintain these values for optimal nutrient adsorption.
2. Growth Stage
Unlike pH, PPM levels change according to the growth stage of our crop. From Osseds Bank, we provide a small table with the optimal values to grow your cannabis plants in hydroponic cultivation.
- Seedling 100 – 250 PPM
- Vegetative Beginning 300 – 400 PPM
- Pre-Flowering 450 – 700 PPM
- Flowering 750 – 950 PPM
- Final Flowering 1000 – 1600 PPM
- Harvest 0 PPM
3. Setting up our hydroponic system
First of all, we recommend you if it is your first time to buy a hydroponics starter kit. Because it will already come with all the necessary materials to start your hydroponic cannabis growing.
In the following hydroponics article, we will include the different setups. Also, so you can learn and get more out of your cannabis crops. However, let’s jump right into the set up of our hydroponic grow kit.
First, once we have assembled our hydroponic system, you must fill the water tank with the help of the water pump.
Secondly, check the required amount of nutrients based on the first stage. After pouring the nutrients into the water tank you have to wait about 30 minutes for it to mix with the water. In addition, you can add beneficial bacteria to prevent harmful microorganisms. Finally, remember the importance of PH and PPM.
Third, plant the germinated seeds and monitor progress through the seedling stage, which lasts about 3 to 4 weeks in feminized seeds. However, in autoflowering seeds it takes about 1 to 2 weeks.
Finally, you should monitor the PPM at different stages of growth in your cannabis plant.
