Five Fruits and Vegetables for Your Hydroponic Garden

You’ve got your hydroponic system, now what? It’s time to get growing! 

Let’s look at 5 fruits and vegetables that are ideal for growing in your indoor garden. 

1. Spinach

The health benefits of this leafy green vegetable makes it a great addition to any healthy diet; spinach can be juiced, sautéed or eaten raw. This unassuming plant is right on top of the list of plants that a beginner can grow in a hydroponic garden. Spinach grown using this method can be harvested all at once, or snipped off bit by bit, leaving the rest of the plant to keep growing.

2. Lettuce

Like all leafy green vegetables, lettuce is a great base for sandwiches and salads. The heads grow rapidly, and are easy to take care of. Good choices are Boston, bib, or butter crunch leaf lettuce. Lettuce is perfect for indoor hydroponic gardens because it gets protected from the sun, keeping it from burning. In many cases, the shade can buy a few more weeks of harvest time than you’ll have from lettuce grown in the sun. Lettuce requires cool ambient temperatures of around 75 degrees Fahrenheit during the day and 55 degrees Fahrenheit at night.

3. Strawberries

Imagine having fresh, homegrown strawberries at your disposal all year round! To get started, you will need to purchase a few strawberry starter runners from a garden supply store, and throw them in your refrigerator. This cold stimulation is designed to help jumpstart the growing process, which means that the strawberry plants will be able to flower soon after  planting.

4. Tomatoes

Useful in so many dishes, tomatoes are both nutritious and flavorful. The fact that tomatoes are vine plants makes growing these fruits in a DWC (Deep Water Culture) hydroponic system piece of cake. We recommend disease resistant varieties such as Daniela as this reduces the level of care required.

If you’re growing tomatoes you’ll need a trellis or some other kind of support system so the vines can grow out. They prefer a warm growing temperatures so the daytime temperature should be ideally set at 70-79 degrees Fahrenheit and 61-65 degrees Fahrenheit at night. 

5. Peppers

Peppers are relatively easy to grow. They prefer warm growing temperatures, similar to tomatoes. However, fruit production can be raised by increasing the nighttime temperatures and slightly decreasing the daytime temperatures while ensuring that they are irrigated with feeding solution up to 6 times a day. Avoid bell peppers unless you have plenty of space in your system. The best pepper varieties to grow hydroponically include green peppers or hot peppers such as cayenne, habanero, and jalapeños.

What have you had success growing in your indoor garden? Good luck with your growing!
