What is more better, Grow bag vs Plant Pot

Planting bags and flowerpots are widely used in the horticulture industry. 

They have several common benefits:

1)They easy to move plants and get more sunshine.

Grow bags and flowerpots are very conveniently to move for an purpose.

You can start a project indoors with a flowerpot or grow bag, and then move it outside.

At the same time, you can move the position of various planting bags and adjust the location and duration of light according to the different growth stages of the plant.

2) Not subject to environmental restrictions.

You no longer have to worry about the poor quality of the soil and the lack of nutrients.

Even if your yard is concrete, you can easily build a garden with grow bags and flowerpots.

You can choose the soil with suitable acidity and alkalinity, add targeted fertilizer, and add it to the planting bag as the culture substrate.

The advantage is that pests and insufficient fertilizers can be avoided to a great extent, resulting in unhealthy plants.

More Benefits from Grow bags:

advantage of grow bags

Better portability and higher plant survival rate.

In the plant germination and young stage, we can adopt the method of indoor planting bag planting, give more care and nutrition, and improve the germination rate and survival rate of the plant.

In the middle and late stages of the plant, the plant has grown healthily.

We can consider transplanting the plant to the land or outdoor garden to absorb more sunlight and dew.

We just need to cut open the plant bag or tear open its own Velcro, and we can easily transplant the plant without any harm to the roots of the plant.

By adopting the method of planting bag transplantation, the survival rate of plant transplantation has been increased by more than 45%, which is why planting bags are so popular.

The growth and extension of the root is more natural.

The material of the planting bag is non-woven, which can ensure the air circulation of the root to the maximum extent.

It will enable the roots of the plant to absorb water and nutrients from the soil in the basin more efficiently, increasing the absorption efficiency by 32%.

At the same time, in the case of insufficient water, the root of the planting bag, due to the full circulation of air, will grow more branches and absorb water in the air.

When the root of the plant touches the boundary of the planting bag, the root of the plant also forms a lateral bud, which makes the root stronger.

This avoids coiled root growth in the planting container.

The plant will have healthier roots and grow faster and more vigorously.

Easy to arrange and improve space utilization.

Based on the fact that the planting bag has different lengths and widths and more diverse shapes, it is very convenient for us to arrange and plant in the limited space, and the flowerpot can not be satisfied.

This is why most tents are planted with grow bags.

Regulating the balance of temperature

Because of the breathability of the grow bag, the heat accumulated in the soil can be dissipated with air circulation and the plant roots maintain the proper temperature.

Maintain appropriate water content.

The fabric of the planting bag is permeable and the excess water in the soil will be discharged to avoid overwatering and causing the plant to rot.

At the same time, the air permeability and water permeability of the grow bag requires regular watering of the crop to avoid the soil from drying out too quickly.

Environmentally friendly and biodegradable material

Planting bags are reusable and can be used for multiple planting seasons after washing, drying and preserving properly, and the material is biodegradable.

They are processed from environmentally friendly, non-toxic needle-punched non-woven fabric.

More space-saving storage

The grow bags are foldable, so when they are not in use, they can be cleaned and dried firstly, and then folded and stored without taking up space in the tool room.

How to use grow bags

how to use grow bags

Planting bags are available in various shapes and sizes, and can be used for flowers, vegetables, fruits, herbs and other applications according to different planting plans.

How to choose the right grow bags?

how to choose grow bags

The first thing we need to consider is the quality of the planting bag.
1, choose the fabric that weighs more than 260 grams, because if the fabric is too thin, the load-bearing capacity is very poor.
2, choose the material of non-woven fabric with anti-tear technology. 
How to test whether it is resistant to tear? 
Try to tear naturally with both hands at the edge of the planting bag, and the fabric with strong tensile ability is better.
3, check the position of all seams planted to make sure there are no leaking seams.
4, check whether the handle has X-type suture to ensure adequate tensile resistance.
Then choose different shapes of planting bags according to the use.
a. In general, you can choose a round planting bag, because it is the most economical and durable, and can be used for most plants.
b. If it is used to plant tents, square planting bags are preferred because it can improve the utilization of space and plant more plants.
c. If it is used for seedling cultivation, choose a planting bag with Velcro. After the plant grows up, it is easy to transplant to the land or larger planting containers.d. 
For potatoes, there is a special planting bag, which is easy to observe the growth of plant roots and harvest crops.
