Best Vegetables For Hydroponics

If you are interested in growing vegetables, but lack the space or location to put in a traditional garden, I am sure you have considered hyroponics.

The next logical question is what can I grow? What are the best vegetables for hydroponics? What about fruit? Can I grow that too?

What Vegetables Are The Easiest and Best Vegetables for Hydroponics?

There there are so many different types of vegetables, and fruits you can grow using hydroponics! The best type for you is going to be a definite mix of how much experience you have growing vegetables and the type of hydroponic setup that works best for your location and budget!

Vegetables that have more extensive roots, such as carrots and radishes, tend to not do so well in a hydroponic garden due to them needing soil and a large amount of space for their root systems to grow correctly.

The best vegetables for hydroponics tend to be the leafier types of vegetables (such as lettuce and kale), or ones which produce some sort of fruit (like tomatoes or cucumbers) and are then done.

While it is technically possible to grow most types of vegetables, we will focus on the more beginner friendly types, and the hydroponic systems which might best suit them.

Lettuce

1. Butterhead Lettuce:

Butterhead lettuce is known for its loose, tender leaves that form a rosette-like head. The leaves are soft and have a mild, buttery flavor.

Because People Ask - FAQs

Here are some "growing" questions concerning the best vegetables for hydroponics. Certainly not all the questions, although they are some of the most common ones:

Can spinach be grown hydroponically?

Yes, for sure! The conditions such as temperature for seed germination, and pH levels are more particular. They are not the best for beginners, but when you are ready for a bigger challenge go for the spinach then.

The 3 types of spinach commonly grown in hydroponics are:

• Bloomsdale
• Smooth Leafed
• Red Cardinal

Can potatoes and carrots be grown hydroponically?

Growing potatoes and carrots (or anything with a tap or tubular root system) hydroponically is possible but not favourable. Sweet potatoes and other varieties of potatoes really require soil to mature healthily.

Potatoes would do much better in an in-ground environment due to their extensive root system versus a hydroponic environment. It also is more cost-effective to grow them in-ground.

They do grow well in containers, and most who do grow them hydroponically usually have large containers of grow medium with a drip and drain type system. 

Can be done, but not the best suited for limited spaces or beginners.

Can mushrooms be grown hydroponically?

Technically yes. It is not a simple and straight forward type of crop as you have to have particular conditions and a very dark room. Not recommended for beginners or apartment size gardens.

Can fruits be grown hydroponically?

Yes! Fruits like strawberries, blueberries, and raspberries are perfectly fine for growing hydroponically. 

Strawberries are one of the most popular commercially grown plants. They are beginner-friendly as they are effortless to grow.

They flourish best under the ebb and flow hydroponic setup or the nutrient film technique (NFT).

Blueberries typically aren't someone's first choice to grow fruits hydroponically due to them not producing any fruit until the second year of growth.

If you are considering growing raspberries hydroponically, Primocane-type raspberries are the better option for a hydroponic system as they provide a higher yield of fruit throughout the year, and they require less space than Floricane type of raspberries. Not a beginner friendly crop by any stretch.

Can I grow herbs in hydroponic systems?

Most certainly! Although most people put herbs in their own category, and so we have put them on a pedestal all their own.
