Fremont, CA: Hydroponics is a good way to try growing healthy plants at home without applying soil. While it may appear counterintuitive, plants grown in hydroponics have greater yields and present a host of other advantages.
Hydroponics works in various scenarios—from growing a small collection of herbs in a kitchen to numerous plants in a large-scale commercial operation. People with confined or no outdoor space, such as urban residents, apartment dwellers, or renters who can’t have an outdoor garden, find hydroponic growing especially useful.

If you’re considering undertaking a hydroponics project, you’ll first be required to learn the fundamental idea of growing plants hydroponically.
5 Drawbacks of Hydroponics
It’s simple to see the advantages of hydroponics. But some diverse disadvantages exist. As with anything, it’s important to understand the drawbacks to avoid surprises.
1. Expensive to set up
A hydroponics system is more costly to acquire and build than a conventional garden. Costs range based upon the type and size of the system purchased and whether or not it’s prefabricated or built with separate components to create a customized design.
2. Vulnerable to power outages
Both passive and active hydroponics systems are based on electricity to power the different components like grow lights, water pumps, aerators, fans, etc. Hence, a power outage will influence the entire system. In active systems, a downfall of power can be destructive to plants if it goes unseen by the grower.
3. Requires constant monitoring and maintenance
Hydroponics needs a higher level of monitoring and micro-managing than growing plants conventionally. To maintain a cautiously controlled growing environment, all system components require constant vigilance—lights, temperatures, and many aspects of the nutrient solution, like pH and electrical conductivity.
The nutrient solution must also be flushed and replaced regularly, and the system parts cleaned often to prevent buildup and clogging.
4. Waterborne diseases
Since hydroponically grown plants are grown in water instead of soil, waterborne diseases are considerably higher. In addition, with the water circulating continuously through the system, infections can spread quickly throughout the growing system, impacting the whole collection of plants. In exceptional situations, a waterborne disease can destroy all the plants in a hydroponics system within hours.
5. Problems affect plants quicker.
Soil protects the roots from intense temperature changes, slows diseases and pests from attacking, and regularly discharges and absorbs nutrients. Without soil to play as a buffer, plants grown in hydroponics systems react negatively to difficulties like nutrient deficiencies and disease much quicker.
