Getting your hands dirty and creating your own DIY floating tray hydroponic herb garden can be a fun and rewarding project, especially if you want to enjoy an endless supply of fresh herbs all year round. Not only does a hydroponic system skip soil entirely, but it also controls the environment for your plants, allowing them to grow two to three times faster than they would in soil.
Understanding the Basics of Hydroponics
Hydroponics is a method of growing plants without soil by instead using mineral nutrient solutions in a water solvent. The basic principle is to allow the plants’ roots to come in direct contact with the nutrient solution, while also having access to oxygen, which is essential for proper growth.
There are different types of hydroponic systems available, each with its own advantages and disadvantages. The floating tray system, or Deep Water Culture (DWC), is a type of hydroponics where plant roots are suspended in a nutrient-rich, oxygenated solution that keeps them hydrated and nourished. This method requires very little maintenance, is cost-effective and is perfect for growing herbs.
Identifying Preferred Herbs for Hydroponics
Not all herbs are suitable for hydroponics, but the good news is that the most popular ones like Basil, Parsley, Cilantro, Mint, Dill, and Chives do incredibly well under floating tray hydroponics system. They have quicker growth rates and produce higher yields in hydroponic systems than when grown in soil.
Materials Needed
Constructing a floating tray hydroponic herb garden requires some basic materials, most of which you may already have on hand or can easily obtain. They include: A container or reservoir for holding water and nutrients (this will also serve as the base of your garden), styrofoam or any other type of floating board, net pots or cups, hydroponic nutrients, air pump and air stone (for oxygenating the water), pH testing kit, seedlings or seeds of your chosen herbs.
Setting Up The Hydroponic System
-
Preparing the Reservoir: First, you need to prepare your reservoir. The container can be any non-transparent and water-tight container. Clean it properly to ensure it’s free of dirt, dust or any contaminants that might harm your herbs.
-
Creating the Floating Tray: Take the styrofoam board and cut it so it fits the opening of the reservoir. Ensure the styrofoam board leaves a small gap around its edges when inserted into the reservoir. This allows for easy removal and helps the plant roots access air.
-
Fitting the Net Pots: Draw outlines of the net pots on the styrofoam board. The distance between the pots should be based on the mature size of the herbs. After you draw the outlines, cut the circles out. Now, you can place the net pots into the holes, ensuring they fit properly but can also be removed easily.
-
Adding Water and Nutrients: Fill your reservoir with water until it’s close to touching the bottom of the net pots. Mix hydroponic nutrients into the water following the manufacturer’s recommended nutrient-to-water ratio. Lastly, check the pH levels of the solution. Herbs love a pH between 5.6 to 6.0.
-
Oxygenating the Solution: Now attach the air stone to the air pump, place it at the bottom of the reservoir and turn it on. You should see a stream of bubbles. This supplies the roots with essential oxygen, promoting faster, healthier growth.
-
Planting the Herbs: For starting from seeds, place them into the sponge or rockwool, then place it in the net pot. If you’re using seedlings, gently rinse off the soil from the roots and place the seedling into the net pot using a growing medium.
Maintaining the Hydroponic Herb Garden
The maintenance process typically includes checking water levels and ensuring they are optimal, regulating the pH levels, as well as monitoring nutrient levels. Weekly checks are recommended to ensure plants have enough nutrients, and the solution is refreshed every two weeks. By observation, you can tell if your herbs need more nutrients. Yellow leaves might indicate a deficiency that requires a nutrient boost.
Keeping A Check on Temperature and Light
The ideal temperature for most hydroponically grown herbs hovers between 65°F to 75°F. Cooler temperatures slow the growth rate while too-warm temperatures can lead to wilted plants. As for light, Hydroponic herbs need a lot of it – a minimum of 6 hours a day. You can provide this using fluorescent or LED lights if natural light is insufficient.
Harvesting Your Hydroponically Grown Herbs
Harvesting is the best part of growing your own herbs. For most herbs, you can start harvesting once they’re around 4-6 inches tall. Remember to only take about 1/3 of the plant while harvesting. This allows the plant to keep growing and providing.
In conclusion, a DIY floating tray hydroponic herb garden is an efficient and effective method to grow your favorite herbs year-round. It requires a small initial investment, a bit of assembly, and maintenance. But the endless supply of fresh, organic herbs you get— even if you don’t have a garden— is well worth it. The freshness and quality are unmatched, not to mention the therapeutic benefits of tending to a garden, even a compact hydroponic one. Be it for culinary or medicinal purposes, the herbs grown in your DIY hydroponic system will demonstrate the benefits of this modern, soil-less method first-hand.
