By properly pondering about the various pros and cons of using a hydroponics system, you will be able to come to a favorable conclusion regarding your plant growing method. If the pros outweigh the cons according to your perception, then you can comfortably go ahead with the process. On the other hand, if you feel it as a risky move, then you may stick to other more conventional methods. All in all, Hydroponics seems to be an efficient system to produce healthy plants and vegetables. Ozone generators are one of the latest, most effective solutions to the problem of air purification when it comes to indoor gardening. Hydroponics gardening can be a rewarding activity, allowing you to enjoy seasonal plants, fruits and vegetables year around. However, without a proper air purification system in place, you'll soon wind up with a heavy, unpleasant musty smell due to the organic wastes that are a product of indoor gardening. Ozone generators can be among the most valuable gardening supplies you can have. Traditional Air Purification Most air filters use activated carbon. The carbon is activated by oxygenation, which results in millions of microscopic pores on the surface of the granules. These 'micropores' trap organic particles that cause unpleasant odors resulting from hydroponic gardening. The main drawback of activated carbon filters is that they can only absorb a limited amount of organic contaminants; except for chlorine, they are useless for filtering inorganic substances, and in any event, must be replaced regularly. Some companies offer carbon filters in which the granules have been treated with polymers or volatile oils, increasing their effectiveness in trapping and absorbing the odor-causing micro-organisms. Nonetheless, these to have limits and must be switched out at regular intervals. HEPA filters, while tremendously effective in eliminating many contaminants, have the same drawback - they must be replaced at regular intervals. The Beauty of Ozone You may have heard of ozone in science news; it actually occurs naturally in the planet's upper atmosphere. You've also probably smelled it if you have ever been around electric toy trains. Ozone is what is known as an allotrope of oxygen; instead of a single molecule, it results from the bonding of three oxygen molecules. Most people don't realize it, but oxygen is actually toxic in large amounts; therefore, ozone is triply toxic. This is actually a good thing, however; instead of simply absorbing and trapping odors, ozone generators actually destroy indoor gardening odors at their source by killing off the micro-organisms that cause them - including mold, mildew and various kinds of bacteria. Ozone generators have been used for a long time in a wide variety of air purification applications. Available at most online and brick-and-mortar retail outlets that deal in hydroponics supplies, ozone generators have been used to clean and sanitize those difficult-to-clean HVAC systems in the ductwork of residential homes, commercial buildings and sea-going vessels. Although ozone generators are not the cheapest indoor gardening supplies you'll invest in your hydroponics gardening career, they definitely have the highest performance-to-cost ratio - and best of all, there are no filters to replace! Ozone generators give you the most air purification 'bang' for the buck.
