How These Net Pots Work

As mentioned, these gardening products include various hole designs key in your Hydroponic system. Let’s look at the container designs which are key to your gardening success.

Holes Designs and Oxygen

The Net Pot’s holes allow for excellent air circulation around your plant, quickly obtaining oxygen. These holes allow the plant roots to dangle freely in the water to access the air component.

  • Enough oxygen enables your plants to absorb more minerals efficiently. 
  • These holes allow ideal aeration for the plant to grow healthy and strong.

Holes and Roots

Net Pot holes enable root movement, unlike growing in soils where they have to toil for aeration and mobility. Therefore, your vegetation in a Hydroponics setup allows the crop to get necessary nutrients. 

Note: An essential tip is ensuring you get the right variety for your chosen plant. Also, get to know the growth rate of your crops to know if the spacing on the pots will be enough.

The Plant Roots as an Anchor

You’ll also realize that Pot sizes pivot the seeds planted to your Hydroponics space. Generally, it maintains within the Net Pot, where the leafy section grows upward while the plant roots are directed downwards. 

Note: The ideal non-soil environment, is one with a deep water culture system, helping your crop grow stronger by creating a balanced Hydroponics context. 

Does Pot Size Matter in Hydroponics Setups? 

Your Net Cups dimensions come into play in hydroponics gardening, directly impacting the plant’s development. Different experts are also advising that acquiring a bigger size is better. Here are examples of a Net Pot’s size:

Why You Should Consider a Net’s Pot Size

There are different advantages to be enjoyed with the correct size Net Pots. You can utilize these tips to understand the impact of a Pot’s size on your plant’s growth. 

1. Impacts the amount of nutrient composition available to the crop

Bigger Net cups hold more minerals, providing the plant with a significant amount of water and key elements. This is essential in larger setups, where plants require more water and elements to thrive.

2. Influences the rate at which the water in the hydroponic system is circulated

A smaller net pot enables water to circulate faster, while a larger pot has a slower water flow. Slower water flow is more beneficial since it distributes nutrients equally throughout the root system.

3. Affecting the amount of oxygen in circulation

Another tip is that having more water in the container means less air circulating. As mentioned, adequate aeration is essential for healthy root growth; thus, a Net Pot size with enough O2 provision is needed.

4. Impacts the overall Plant stability 

Acquiring a smaller net pot may cause instability for larger plants, causing imbalance or breakages. On the other hand, a larger Net Pot version may provide too much space for smaller vegetation and potentially damage the root system.

Why You Should Consider if the Lip and Lid Fit

A pot’s lip should fit your hydroponic gardening system. More lip is mostly preferred in the industry. The pot’s lids also need to be the perfect fit to protect the gardening setup from excess light, ideally.
