Plant diseases or blights in a hydroponics garden are much less frequent than in a dirt garden because there is no dirt to grow bacteria. Not to mention the fact that many plant diseases travel to the plant from the surrounding soil. Plant disease cannot occur without a host plant, a pathogen, and favorable environmental conditions.
Plants can be more susceptible to disease if weakened by environmental
conditions such as too much shade, high humidity and crowded conditions.
They are also more susceptible when weakened by nutrient deficiency or
toxicity (too many nutrients) and poor pH.
There will always be some trouble with disease, just watch for it and take care of it immediately. Unfortunately, many disease cures involve the use of harsh chemicals which you really do not want on your plants. A hydroponics garden can easily collect such chemicals in the nutrient solution with indiscriminant use and get into the plant cells - not something you want.
What to do About Them
Try some less harsh solutions first. Our favorite all-purpose cure is to mix water, baking soda, lemon juice and a very little bit dish detergent. Put this in a spray bottle and mist the affected parts of the plant. If you mix and use this recipe, make sure you cover all open areas to your nutrient solution or the dish detergent will get into it, causing soap bubbles.
Hydroponics - The Future
"Gas and food prices are increasing, persuading people to take matters into their own hands." The National Gardening Association expects 43 million American households to grow their own fruits, vegetables, herbs and berries this year." That's up 19 percent over last year, according to a household survey the group conducted in January (Sutter, 2009).
People are enjoying the satisfaction of growing their own food, the enhanced flavor and the saved money they benefit by doing it themselves.
"Environmentally friendly" has become a mantra amongst those wanting to preserve our planet and stop the exploitation of the very land we depend upon. With this, many are utilizing the benefits of composting and growing their own food. This trend to protect and sustain our fragile planet is one that will continue to grow in the future. The movement towards a more health conscious society is on the rise, providing an unmeasured opportunity for hydroponics and organic gardening.
Not only are individuals growing their own food, but restaurants and even grocery stores have implemented their own gardening centers to offer fresh, local produce to their customers. They have heard the voice of the people wanting uncontaminated foods grown in their own community.
