Hydroponic Gardening Frequently Asked Questions

What Is a Hydroponic Garden?

Unlike traditional gardening where plants collect their nutrients from the soil, hydroponic plants collect their nutrients from a solution dissolved in water and applied in different ways. Some techniques used are applying mist to the plants, flooding with water, or roots being suspended and dipped in water.

What Are the Benefits of a Hydroponic Gardening?

  • Plants can be grown all year round since it is commonly done indoors
  • It can save up water since it is controlled and the nutrients can be controlled as well
  • It can maximize space since you can place plants closer to each other
  • Plants grow faster and more efficiently
  • Weeding will never be a problem
  • Pests from the soil will not be a problem and will lessen the use of pesticides

What Should Be the Growroom Temperature?

Growroom temperature will depend on what plants will be grown. For tropical flowers like orchids and succulents, 80°F is ideal. For more cold-loving plants like kale and broccoli, 60- 65°F should do the trick. Meanwhile, tomatoes should grow well in 68-75°F.

It is important to note the temperature because going below or way beyond it can potentially ruin or kill the plants.

How Long Can Plants Go Without Water?

A general rule for hydroponic gardening in terms of watering plants is to water it as much as the roots will get wet but not too much that it will drown the plants.

Leaving a plant on its own without watering will also depend on how big it is and how you think it will collect water for it to grow. It can also depend on the system being used, the humidity, and the temperature.

It is best to check on the plants every two to three days and see the quality of the plants.

How Is It Different From an Aquaponic Garden?

An aquaponic garden may use the same system but has the advantage of using aquaculture to help breed the plants. The nutrients are more natural since it comes from the fishes which benefit from the plants and vice versa.

In soil gardening, plants get their nutrients from the soil. The roots extend and dig through the ground until it collects all it needs. In hydroponics, nutrients are fed to the plants through a solution mixed in water.

The solution consists of the following:

  • Potassium
  • Nitrogen
  • Phosphorous
  • Calcium
  • Magnesium
  • Sulfur
  • Iron
  • Manganese
  • Copper
  • Zinc
  • Molybdenum
  • Boron
  • Chlorine

Can I Do Hydroponic Gardening Outdoor?

Yes, but it will be a bit difficult to run a hydroponic garden outdoor. Although it is important to keep in mind the solution given to the plants must be kept at the right temperature since it may become too cold or too hot outside. However, heaters and chillers can be used if there are no other options.

A gardener must know the challenges they may face when a hydroponic garden is set outdoor. Low temperatures can slow down the growth of plants while high temperatures can damage the root or can cause anaerobic bacteria.

How Is It Different From Soil Gardening?

|

Hydroponic is different and better than soil gardening for multiple reasons. First of all, this type of gardening can result in more space because plants can be stacked on top of each other.

Next, the nutrients needed by the plant are directly given to the roots compared to soil gardening where the root will grow farther searching for food. At the same time, the plants get more oxygen in this process which can result in a better growth rate.
