What Cannot Be Grown Hydroponically
What cannot be grown hydroponically? The surprising truth.
When it comes to hydroponic gardening, there seems to be a belief that all plants can be grown hydroponically. While hydroponics works brilliantly for many crops, it may not be the best option for some plants. In this post, we will discuss what plants cannot be grown hydroponically and why.
Explanation Of What Cannot Be Grown Hydroponically
Hydroponics is a soilless method of growing plants that involves using nutrient-rich water instead of soil. However, not all plants can thrive in this environment. Some plants need soil for support, while others require a specific atmosphere that is challenging to create hydroponically.
Here are some plants that cannot be grown hydroponically:
Plants That Require Soil For Growth
Plants that require soil for growth have roots that need to anchor them to the ground. These include:
- Crops with taproots: Plants such as carrots, parsnips, and turnips have long taproots that help them draw water and nutrients from the soil.
- Plants with rhizomes: Plants such as ginger and turmeric grow from rhizomes, which are modified stems that grow underground.
- Bulbs: Onions, garlic, and other plants that grow from bulbs need soil to anchor the bulbs in place.
Reasons Why Soil-Based Growth Is Better Suited For Some Crops
While hydroponics is great for growing many crops, soil-based growth offers several advantages for some plants. Here are some reasons why:
- Plants that require a specific ph level: Some plants need a specific ph level to grow healthily. It can be tough to maintain the ph level when growing hydroponically, making it easier to do so with soil.
- Water-hungry crops: Some plants require a lot of water to grow, which is challenging to maintain hydroponically. For example, rice requires an immense amount of water to grow, making it better suited for growing in flooded fields.
- Plants that require a specific atmosphere: Soil-based growth is better suited for crops that require a specific atmosphere, such as those that need high humidity or a specific temperature.
Hydroponics is an excellent way to grow crops, but it may not be the best option for every plant. Plants that require soil for support, or those that need specific atmosphere or ph levels, are better suited for soil-based growth.
