Beans can also be grown hydroponically but may require a bit more space due to their climbing nature. However, many varieties are self-pollinating, which reduces manual labor needs. They can easily be trained to grow on trellises or support structures, which simplifies plant management.
Simple Fruits and Berries
Although slightly more challenging, hydroponic systems can support fruiting plants like strawberries and small blueberry varieties. They will need adequate light and care, but offer a sweet reward for your efforts. They have small footprints. Strawberries is self-pollinating and can produce fruit relatively quickly after planting, especially everbearing varieties that produce fruit throughout the growing season. Blueberry plants can produce fruit for many years, making them a long-term investment for a hydroponic garden.
Houseplants and Decorative Flora
For non-edible options, consider adding some of the best hydroponic flowers and decorative plants to add some color and life to your space. These can also be a good practice ground for branching out to more complex hydroponic plants.
Marigolds are robust and can thrive in a hydroponic setup with minimal care. They are known for their pest-repellent properties, which can be beneficial in a hydroponic garden. Zinnias and Geraniums grow quickly and can bloom in a variety of conditions, making them a good choice for beginners. Impatiens are shade-loving plants that are suitable for hydroponic systems, especially those with lower light conditions. Petunias can flourish in hydroponic systems, producing an abundance of flowers when provided with plenty of light. Begonias can be a good choice for hydroponic growth due to their preference for high humidity environments, which is something easily controlled in a hydroponic setup.
Spider plants are highly adaptable and are forgiving of fluctuations in light, temperature, water levels and nutrient concentrations. They readily produce offsets that can be removed and placed directly in water or another hydroponic medium to start new plants, making propagation simple and efficient.
All these plants can handle the consistent moisture levels found in hydroponic systems without succumbing to root rot or other water-related issues. They can adapt to the nutrient solutions used in hydroponic systems and don’t require complex nutrient regimens.
Advanced Hydroponic Plants
Advancing in hydroponic gardening opens up a world of diverse plant options that can yield impressive results. While these plants may require more attention and care, your hard work will be rewarded with unique flavors and stunning visuals.
Challenging Vegetables and Fruits
When you’re ready to step up your hydroponic game, consider trying your hand at growing root vegetables like carrots and potatoes, which might test your skills as they normally require a medium like sand or perlite to support their growth and need careful timing for harvest.
Exotic Herbs and Spices
While many herbs are relatively easy to grow hydroponically, some can present moderate challenges due to their specific growth requirements, sensitivity to environmental conditions, or susceptibility to pests and diseases. Here are a few herbs that might be considered moderately difficult to grow hydroponically, especially for those without much experience:
- Dill: Dill has a tendency to bolt (flower and go to seed) if it’s not grown under optimal conditions. It requires careful management of light and temperature.
- Tarragon: French tarragon, which is the variety most prized for its flavor, can be more challenging to propagate and grow compared to other herbs. It can be sensitive to overly wet conditions and may require careful water management.
- Chives: While not particularly difficult to grow, chives can take time to establish from seed and may not produce as quickly as other herbs. They also prefer cooler temperatures and can be sensitive to high heat.
- Sage: Sage can be prone to root rot in hydroponic systems if the water is not well-oxygenated or if the system does not allow for sufficient drainage.
Flowering Plants and Ornamentals
If you’re leaning towards beauty in your hydroponic venture, flowers such as carnations can be quite rewarding. They have an extended blooming time with controlled lighting schedules. Hydroponic flowers, in general, are an attractive option for growers looking to achieve longer blooming periods and potentially better flower quality.
Specialty Fruits and Berries
Growers with a passion for sweet rewards might opt for specialty fruits and berries like watermelon, melons, and grapes. These crops generally take more time and space to produce fruit, but growing them hydroponically can yield impressive, high-quality produce.
