What Are The Pros And Cons Of Grow Bags?

Grow bags are gaining popularity among many gardeners because they are easy to use even for beginners.

Grow bags allow growth for a better root system

One of the best advantages you can get from a grow bag is its breathability. Since the material of the bags is very breathable, grow bags allow better air circulation which is great for a plant's root system. If you've ever used pots before, you will notice that roots tend to circle and surround the pot as it tries to look for air and nutrients.

With grow bags, the roots automatically prune themselves when they get in contact with air. This is what we call air pruning, wherein the plant's roots dry out when they find air. This makes the plant create more root tips, which gives the plant better chances of growing and utilizing the nutrients of the soil.

Grow bags have excellent drainage

Since grow bags are made of fabric, you can lessen the possibility of overwatering. Water will easily drain through the fabric of the grow bags. The plants will be damp enough and there is less risk of the roots becoming rotten due to excess water. Keep your grow bags raised in your garden so that they will not absorb the puddle of water on the ground.

They can be easily stored

Unlike pots and other containers, you can easily fold grow bags and keep them in your shelf or cabinets. After using them for a season, you can simply wash them clean and let them dry before storing them for next year. If you don't have the space to keep stacks of pots, grow bags are great alternatives, especially for seasonal plants.

They have multiple sizes and come in different colors

Just like their pot counterparts, grow bags also come in multiple sizes, depending on your needs. Grow bags come in sizes from seedling starters to 100-gallon grow bags which can immediately turn into a raised garden. They also come in different colors which adds to the whimsy of these plant containers. If your plants need warmer soil, black grow bags can help with this issue.

Grow bags have more surface area

The bottoms of grow bags are flat, which gives you more space for your soil. Unlike the tapered bottoms of plant pots, grow bags are a lot more stable when they are sitting on a flat surface, so they will not fall over easily. Since grow bags also have more soil, the roots are able to get more nutrients and are generally healthier.

Seedlings are unlikely to be root bound

If you are planning to propagate and get a headstart for your seedlings, grow bags are a great option to grow them. Since the grow bags are breathable, the roots will go through air pruning early and they will grow better when they need to transfer to a bigger container.

Some grow bags are flimsy

Depending on the brand of grow bag that you have, some of them are not as durable compared to pots. Because of the fabric of the grow bags, they will disintegrate over time and the handles may rip or the bag has become flimsy. Try to look for grow bags that have handles with good stitches and fabrics that are thick and rip-proof.

They dry out quickly

Grow bags do have good drainage, but it can also be a problem because plants can dry out quickly in grow bags. Water evaporates faster in grow bags so you cannot leave plants unwatered for a few days, unlike pots. Try looking for ways to retain water by adding mulch to your pots to keep the moisture in.
