As a gardener, I love getting my hands dirty. I love the feel and smell of rich, damp soil. I love its earthiness. It makes me feel connected. As a result, I never gave hydroponics a chance. I was wrong.  Hydroponic lettuce (Marsraw) Pixabay Hydroponics refers to growing plants in water that has been infused with nutrients. Plants grown hydroponically may have their root systems supported with slotted cups or other mechanical means, or they held in place with gravel, perlite, or other inert material. So, how did I get started with hydroponics? In my high-rise apartment, we have a Free Bench. A Free Bench is any space where neighbors can put things they no longer want, and others can freely take whatever they like. It’s a great way to reduce waste and clutter at the same time. If your apartment or neighborhood doesn’t have a Free Bench, I urge you to create one. I recently saw a brand-new AeroGarden hydroponic herb garden, complete with seeds and plant food, on our Free Bench. I had to grab it and give it a try. The concept behind hydroponics is simple. A bowl-shaped base contains water and a water pump. The water pump circulates the water periodically, preventing swamp-like conditions. This circulation aerates the water.  My hydroponic garden on January 20th The bowl has a flat lid with holes. Cone-shaped containers of inert material contain seeds. These cones fit nicely into the holes. An arm at the back of the bowl supports a grow light. This arm can be raised or lowered, depending on the height of the plants. What’s so great about hydroponics? The best thing about hydroponics is that there is practically zero water waste. The container is covered, reducing evaporation, and the roots pull up as much water as they need. No more and no less. According to Wikipedia, it takes 57 gallons of water to grow 2.2 pounds of tomatoes in soil. Growing the same tomatoes hydroponically takes 18 gallons, and growing them aeroponically only uses 5.3 gallons. We will discuss that method another day. So, you can’t overwater. Overwatering is probably the most common cause of death for indoor plants. The worst thing you can do for your hydroponics irrigation-wise is to forget to top off the water as it gets used by the plants. Luckily, my unit has a warning light that tells me it’s time to add water. It also has a light that tells me when to feed my water-bound plants. The kit came with its own plant food. When that is used up, I will probably start using fish emulsion. My hydroponic plants get all the light they need from LEDs built into the unit.  My hydroponic plants are putting out serious roots by February 1st! To create your own hydroponic planter with a yogurt container, use these steps:
*Do not fill the container to the top. The roots need some air exposure, or they will drown and die. It won’t be as convenient as the automated version since you must monitor it more closely. But you can grow a surprising amount of food this way. Commercial hydroponic facilities currently grow cucumbers, lettuce, peppers, spinach, and strawberries, along with all those tomatoes. As water supplies dwindle and weather patterns continue to change, hydroponic gardening may very well be the agriculture of the future.  One week later, I can harvest some dill, and the basil and mint are nearly ready for their first pinching! It’s a great way to have fresh herbs, even if you live in an apartment. And the space above the lights makes the perfect spot for drying those herbs!  UPDATE (March 7, 2025): The rate at which my hydroponic herbs are growing continues to impress me. And the basil leaves are the biggest I've ever seen (and delicious)!
