Root crops finish below the soil line, which is why lifting them is the slowest job in a grow bag. These bags cut a window into the side wall, so the lower half of the crop can be picked as it sizes up while the plant above keeps growing. The body is non-woven felt fabric that holds its shape under wet compost, drains surplus water and breathes, with two stitched handles that carry a full load. Sizes run from 1 to 500 gallon, colours from black and green to a buyer's own swatch, and the bags fold flat between seasons.
Potatoes, carrots and salad crops all finish below the soil line, which makes lifting them the awkward part of the job. These grow bags cut a window into the side wall, so the lower half of the crop can be picked as it sizes up instead of being dug out from above.
The body is a non-woven felt fabric heavy enough to hold its shape under wet compost, with an opening turned and stitched into the side wall. Roots that reach that opening meet air and stop there, so the root mass stays fibrous instead of circling the base of the bag. The same wall breathes, so surplus water drains away rather than sitting around the roots, and two stitched handles take the weight when a full bag is carried. The callouts below mark the parts that take the load and the opening the crop comes through.
Home gardens, balcony rows, urban farms and nursery benches all use the same bag: fill it, plant it, and pick through the window as the crop comes on. Potatoes and carrots come out a few roots at a time without disturbing the plant above, while greenhouse tomatoes, peppers and leafy greens grow on in the same container. The bag stands through more than one season and folds flat for storage in between. The wall system is shared across the air pruning pot range.

A full bag is heavy, so the two handles are stitched into the side wall rather than tacked on top, and take the load when the bag is carried from bench to bed. The rim is turned and stitched so the bag keeps its shape when it is dragged, and the window flap folds back into place between pickings. Larger formats move on pallets or trolleys rather than by hand. The biggest sizes sit with the tree and nursery container range.
Sizes run from 1 gallon up to 500 gallon, with colours in black, green or matched to a swatch, and logos printed on programme orders. Bulk orders ship in bags, on pallets or in cartons, with 500 pieces to a carton on the standard size, and the flat bag stores in a fraction of the space a rigid pot takes. Samples let a buyer plant one before committing to a container load. Flexible soft containers sit in the planting bag range. Growing media and container supply is covered at HortiDaily and FreshPlaza.
What does the side window do?
It opens the lower part of the bag so potatoes, carrots and other root crops can be picked as they size up, without lifting the plant out or disturbing the roots above.
Which sizes and colours are available?
The range runs from 1 gallon to 500 gallon in black, green or a customised colour, with printed logos on programme orders.
How are bulk orders packed?
In bags, on pallets or in cartons, with 500 pieces to a carton on the standard size and mixed sizes combined in one load.
