By changing the water frequently for about two to three weeks, you can reduce or even eliminate the bad odor in your hydroponic system.
Hydrogen peroxide comes with devastating effects on microbes and organic tissues. It helps to reduce the growth or destroy viruses, bacteria, and common pests. Aside from reducing the smell of the hydroponic system, hydrogen peroxide is also beneficial for treating root rot, pre-treating seeds, pest control, and killing fungus. It also stimulates nutrient absorption and root growth. Hydrogen peroxide is also helpful in enhancing the oxygen content in water. It can boost overall plant health and growth.
Use air pump
With the use of an air pump, you can produce more oxygen into your hydroponic system. It is beneficial to avoid a smelly growing room.
Use inorganic materials as a medium
Bacteria are a major cause of smelly hydroponic systems. The best thing to solve it is to use inorganic materials as the medium in your hydroponics. You can use rockwool, perlite, grown stones, and hydroton. Inorganic materials are sustainable and reusable, and easy to use.
Check the microbial balance of your hydroponic garden
If microbes cause a bad smell, make sure to check the microbial balance of your hydroponics. Microbial species release slime, foul odor, and other undesirable problems in your hydroponics. With this, you should have a sterilized and clean water source. Then, you can add nutrients and beneficial microbes.
Beneficial microbes work well with the plant’s roots since they promote more minerals and nutrients and fight off parasites and diseases. You can mix it with the nutrient solution to balance the pH level. Keep in mind to keep the nutrient solution oxygenated, so bringing the good microbes will work. It is a good way to keep your hydroponic system healthy.
If a temperature problem causes a bad smell, you can set up a carbon filter. It features controlled temperature settings and timers through its fans that clean the smell and release odorless air. The fans of the carbon filter kick in as the temperature gets above the recommended range and blow air at specific intervals. Carbon filters are easy to use and install. It is effective in removing the bad smell from the areas of your hydroponic system.
Meanwhile, the wrong carbon filter can worsen your hydroponic system. So, you should choose the best carbon filter to produce the best results. In selecting a carbon filter, you can consider the following:
l The filter should come with a deep carbon red for more carbon that lasts longer.
l The carbon needs to contact air, so the airflow between the fan and carbon can match.
l The right spigot size needs to fit on the fan’s diameter snugly. If it’s too small, there will be no air that will flow from the fan into your hydroponic system.
Reduce the use of organic materials
Another way to minimize the smell of your hydroponics is to reduce the use of organic materials for the growing support of your hydroponic plants. It is also essential to maintain pH levels in the nutrient water to prevent microbes. You can clean or replace the growing medium to eliminate unwanted organic matter. It is good to use a dark reservoir and keep it covered to keep foreign organic matter and light out.
Keep Proper temperature
In hydroponic gardening, the temperature is crucial to maintain plants in the water for growth. The suggested temperature for your hydroponic system is about 65 to 75 degrees Fahrenheit. If it gets too hot in your hydroponic system, the plants may secrete more organic solutions that lead to bacteria growth.
Clean your hydroponic system
Cleaning your hydroponic system is an effective way to remove the unpleasant odor from your hydroponic system. You can replace the nutrient water with bleach mix and water to remove the odor. Remember that water and nutrients need to purify and clean every 1 to 2 weeks.
Use Sanitizing spray
You can use a sanitizing spray to eliminate the smell. The spray contains glycol molecules that will attach to odor-causing compounds in the air and change their chemistry.
Install Exhaust fan
An exhaust fan can draw air from your hydroponic system and vent it outdoors to disperse the smell. In addition, it also helps to offer a fresh and stable supply of carbon dioxide for your hydroponic plants.
Neutralizing crystal or gel
A jar of formulated crystals or gel in your hydroponic system attracts the VOCs (volatile organic compounds) in the air, which carry foul odors and trap them.
Ozone air care program
You can equip your hydroponic garden with an ozone air care program to control the odor in your system. In addition, it also helps increase enjoyment and success in your hydroponic gardening. By installing an ozone generator, you can eradicate the bad smell that can bring inconvenience to your hydroponic system. There’s nothing to worry about because an ozone generator is compact, lightweight, easy to install, and energy-efficient.
Excess ozone in the water breaks down into oxygen which oxygenates the nutrient solution. It helps for fast and healthy root development. Ozone generators are beneficial for odor control in your growing room.
You prefer non-aerosol air fresheners to eliminate bad smells in your hydroponics. It can also add a pleasant fragrance to your garden. Meanwhile, we don’t advise you to rely on air fresheners as the primary source of odor control. However, it is handy if you need to mask the unpleasant smell.
Sterilize the system
If a pH level problem causes a foul odor in your hydroponic system, you can sterilize your system with water and bleach solution. However, the bleach should not contain chlorine.
Flush the hydroponic system and replace your nutrient solution more often
One way to reduce the smell is by flushing the system and replacing the nutrient solution regularly. We advise you to replace your solution weekly or about every two weeks. You can set the system up, so the water pipe can be opened easily to drain the system. Make sure to empty your system if there is a low reservoir.
Drain the nutrient solution into the watering can until the pump begins to draw air. You can add a gallon of pH-adjusted water to the system and run it for about five minutes to flush. Then, you can drain the system again and fill it with a pH-adjusted nutrient solution as well as beneficial microbes.
Check humidity and heat
It is advisable to check humidity and heat in your hydroponic system. Too much heat can kill your plants and lead to mold growth that can bring unwanted smells.
