What is Cannabis Hydroponics? 

The word “hydroponics” was obtained from a Latin language which means “water working”. Hydroponics is an advanced method of growing cannabis in a bath or flow of water that is highly oxygenated and enriched with nutrients. With hydroponic growing, there’s no soil used and plants grow in an inert and sterile growing medium. The nutrients of the cannabis seeds are mixed in a water solution. There’s no need for extra energy or massive root webs for nutrient absorption in hydroponics because the water, nutrients, and air are all provided through the medium.  

Why Grow Autoflowering Cannabis Seeds Hydroponically?  

  1. Autoflowering cannabis can benefit from the readily available air, water, and nutrients of a hydroponic setting.  
  2. The hydroponic system is suitable for drought-stricken areas since no water gets lost through evaporation.
  3.  All plants, including cannabis, do not really require soil, and the necessary elements present in a hydroponic medium can provide autoflowering strains the right nutrients they need, including Potassium (K), Nitrogen (N), Phosphorous (P), Sulfur (S), Calcium (Ca), and Magnesium (Mg).  
  4. With hydroponics, you can make an all-purpose nutrient solution which includes the secondary elements such as Copper (Cu), Boron (B), Zinc (Zn), Molybdenum (Mo), Chlorine (Cl), Iron (Fe), and Manganese (Mn). It will get yourautoflowering marijuana plant through all stages of growth and development, and you just have to make some nutrient levels adjustment depending on the plant’s stage of growth. 

Germinating Your Autoflowering Seeds  

Because you will not use soil in a hydroponic setting, you need a growing medium like Rockwool. It supports the plant roots as well as the nutrient solution. Take the autoflowering seed and surround it with Rockwool. Submerge the bottom up to 70% of the cube into the water. The roots will grow and once they’re about 1/8 inch long, take the autoflowering cannabis seed and place the root down on the hydroponic garden’s growing medium. 

How to Grow Autoflowering Cannabis Seeds Hydroponically 

  1. Providing Nutrients 

You don’t have to worry about giving a higher nitrogen concentration if the temperature of the grow room is higher than 80 degrees Fahrenheit. However, once the temperature reaches below 80 degrees Fahrenheit, you need to provide a higher nitrogen level to your autoflowering cannabis. You can experiment with pre-made nutrient solutions and non-essential additives if you’re an experienced grower. However, if you’re just a beginner, just stick and learn with the basics first. Always keep in mind that fertilizer can kill your weed, so avoid giving too much. You also need to change the nutrient solution once every 2 weeks.   

  1. Refilling Water 

The water in the tank will eventually evaporate as well as get absorbed by your autoflowering cannabis plants. It will result in the dropping of the water level in the reservoir. You need to refill the reservoir or tank with tap water. Don’t allow the water to age more than 3 days and don’t add any nutrients when you are refilling the tank. 

  1. Correct Any Imbalances 

Use a pH meter to help you determine if the solution has the right acidity level which is crucial for the healthy growth of your marijuana plant. Use a PPM meter to determine the amount of element available in your solution. It will ensure that you provide the right amount of nutrients without over fertilizing the medium and the plants. The pH level should be 6.0 for a healthy growth.  

  1. Providing Proper Lighting 

You can use High-Intensity Discharge or HID lights like High-Pressure Sodium or HPS or Metal Halide or MH lights for growing. LED lights are also a great option. However, for the best light used for the vegetative phase, the closest to any regular room light is an MH light. For the flowering stage, you can use HPS. LED lights offer a good light spectrum perfect for all stages of growth and they are better than HID lamps. LED lamps (50 Watts) are highly recommended. Reflective wall covering is highly beneficial to your autoflowering plants so the photons are used toward your plants.  

  1. Grow Room for Autos 

Autoflowering cannabis seeds are amazing. They start the flowering phase once they reach the proper age or maturity level without triggering the flowering phase. Autos are hybrids of indica, sativa, and ruderalis. You don’t need separate rooms for your autos during the vegetative stage and flowering phase. It means that you can grow your autoflowering plants even if they have different ages all together. They have a shorter vegetative period and they flower as early as 3 weeks. 

  1. Facilitate Proper Air Flow or Ventilation

Cannabis plants utilize both carbon dioxide and light for photosynthesis. Use intake and exit vents to bring carbon dioxide-enriched air into your cannabis grow room and to expel carbon dioxide depleted air out. Install an extraction fan to facilitate proper ventilation. Use an oscillating fan to help your cannabis plants straighten their stems. Green CO2 Systems highly recommend carbon dioxide bottles to supply the CO2 requirement of your autoflowering plants. 

Conclusion 

Grow autoflowering cannabis seeds in a hydroponic setting confidently. It is an advanced growing method that you can try in your indoor grow room. It will provide you with a quick and high-quality yield. Now, you know how to grow autoflowering cannabis seeds hydroponically! Happy growing!
