Basically, a grow bag is a flexible poly container that replaces a rigid pot. And it’s so lightweight, that it requires less material to produce, so therefore it’s less expensive.

TDI manufactures most commonly required sizes of custom plastic packaging at a fraction of the cost you would normally pay.

How To Use A Nursery Grow Bag In 6 Easy Steps


Following are 6 simple steps to prepare a nursery grow bag for usage. Of course, this is just a general guideline.

First, remove a flat plant bag from the box and completely unfold along the side gussets.

Then, push out the bottom portion so that it becomes square and will make the bag stand up straight.

Next, roll down the top edge for added stability.

Usually, there’s no need to do this with heavier bags, because they’re already stable enough. However, many of our customers do roll them over to act as a reinforcement handle or for transportation purposes.

STEP 4: Fill with Soil

Thereafter, fill the bag with quality potting soil and/or other media. Please make sure to leave plenty of space from the top.

Now carefully insert your seeds or plant inside the middle portion, away from the edges. Please don’t overfill the pot to prevent overcrowding; always leave enough room for future growth. 

STEP 6: Fill with more Soil

Finally, fill up the rest of the bag with soil, slowly adding water and pushing down to eliminate air bubbles. At this point you will notice that water drains from the vent holes.

Once completed, you can now use your nursery bag in the field, under a covered area, or in your greenhouse.

Q&A’s – Nursery Grow Bag

Here are some answers to frequently asked questions by our nursery partners:


What plants can I use nursery bags for?

Answer: Basically, any plant that normally grows in a container can thrive in a nursery bag. Plastic grow bags can be used for all kinds of species, like flowers, different plants, and trees. 

Can plants become root bound?

Answer: In a traditional pot, roots can start spiraling and become pot bound (or root bound). This will not happen with TDI’s grow bag, because air vents cause oxygen flow to die off roots. As a result, remaining roots become strong and fibrous.

Who uses TDI’s Nursery Grow Bag?

Answer: Wholesale nurseries, greenhouses and hydroponics growers use large quantities of our plant bag in the field or in covered areas.

What soil will give the best results?

Answer: With the selection of quality potting soil your plants will thrive. Especially organic soil works best to produce healthy, strong plants.

Can my plants rot in a nursery grow bag?

Answer: Even during heavy rains, the holes create an excellent drainage system that prevents root rotting. In fact, with our bags, nutrients stay inside the bag so they don’t wash out. 

Good to Know

How To Calculate The Usable Space:

To figure this out, deduct half of the size of the gusset from the height measurement. For example, if the height of your bag is 15 inches, but the gusset is 10 inches, then the actual usable space/height is 15″ – 5″ = 10″

However, if you choose to fold over the top edge, it will clearly impact the height of your bag.

Additional tools:

Some plant species require additional tools to help them grow better, such as a humidity tray or a drip irrigation system to nurture them from the top down. It all depends on your plant species.

As each species of plant has different needs, it’s best to create a customized container, geared towards its needs.

However, it’s up to the grower to figure out what specifications works best for them. (for example: custom size, gauge, and vent holes)
