There are different types of disease that can threaten your hydroponic garden. However, plant pandemics in a hydroponics garden are much less frequent than in a conventional soil garden because there is no dirt to grow bacteria. It is mostly a sterile environment. Plants can be more vulnerable to pathogens if weakened by environmental conditions such as too much shade, extreme hot, high humidity or crowded conditions. Read about the plant growth enhancers that helps in better yields! If you get a pest infestation in your hydroponic garden, the first means of defense is identifying the type of pest.
Let’s check some common hydroponic plants diseases and their solution:
- Botrytis: This is the most common fungus caused by improper ventilation around plants. It’s a dirty, greyish-white growth on the plants leaves. To fight with it, you need to take a soft, dry cloth and remove the mold carefully from the leaves or you can decrease humidity and, clean the garden for debris and remove it.
Powdery mildew: At the initial stage you will notice small white spots on the top of the leaves and finally the leaves will probably shrivel and die. This kind of fungus can hamper plants growth and eventually withering and falling off. You need to decrease humidity level, increase air circulation, light intensity and apply homemade organic spray to eliminate the problem.
- Damping off: It is a kind of fungus that generally affects your newly planted seedlings. It develops where the stems meet the soil causing the seedling to dampen and finally die. To protect your seedlings, never sow your seeds too thickly and pick out the seedlings immediately once they come up.
- Algae: It’s a greenish tinge that covers the top of the plants. Algae is not a serious problem but it is a signal that you need to take care of the humidity levels inside your grow room. To get rid of the problem, remember to scrape of the algae properly and sterilize your hydroponics systems between planting with 10% bleach solution.
