Open-top coco coir grow bags for commercial growers
An individual, pot-free format for nurseries, berries, ornamentals and specialty crops.
Each bag is supplied pre-filled with a coco pith and husk-chip blend, reducing the separate handling involved in filling pots. Commercial buyers can confirm the dimensions, blend, drainage layout and product specification for the quoted format. Distributed from our Cambridge, Ontario warehouse for Canadian and US commercial orders; Mexico availability is confirmed by destination.

Ready-filled bags for individual-container production
Open-top bags provide an individual container-style format without requiring a separate rigid pot. They can suit nursery benches, tabletop berry systems, ornamental production and selected greenhouse crops. For long-cycle crops, confirm the root-zone volume, blend, drainage and irrigation approach before ordering.
Position, hydrate, plant
The substrate is supplied inside the bag, reducing the separate handling involved in filling pots or containers.
Defined EC target
Request the applicable EC target, test method and batch documentation for the product being quoted.
Crop-specific blend and drainage
Pith and husk-chip proportions influence water retention and air space. The appropriate configuration depends on crop, container geometry and irrigation programme.
Commercial bag specification
Confirm the bag material, thickness, UV specification and drainage configuration in the quotation. Suitability for repeated use depends on handling and growing conditions.
Confirm documentation
Before approving an order, confirm the product specification, current inventory, pallet configuration, destination and available batch documentation.

Pallet buying details
Specify the bag before requesting pallet pricing
Send the plant count, bags required and root-zone volume selected by your crop team. For a gallon-labelled bag, confirm expanded litres and dimensions rather than choosing by the name alone. Include the pith/chip grade, treatment, emitter position and drainage opening layout.
The 2-gallon pallet shown is a packing reference, not confirmation of every size or pack count. Ask for bags per pallet, packed dimensions and gross weight for your selected format. Send the delivery postal or ZIP code, planting window and dock, forklift or liftgate requirements. Compare horizontal grow bags only if they fit your bench or gutter layout.
Request bag & pallet pricing →Place, hydrate, plant — in 6 steps
Follow the preparation instructions supplied with the ordered product and confirm that drainage is functioning before planting.
Position
Place the bag in its final supported location before hydration.
Hydrate
Apply water gradually and evenly according to the supplied preparation instructions.
Expand
Check that the material has hydrated evenly; timing varies by bag size, blend and water application.
Fluff
Check the surface and centre for even hydration without disturbing the intended substrate structure.
Plant
Create planting holes or remove plugs, then insert seedlings, cuttings, or transplants directly.
Irrigate
Set irrigation and nutrient management for the crop, water quality and production system with your growing adviser.
Open-top bag or standard flat grow bag?
The correct choice depends on crop spacing, root-zone volume, bench or gutter dimensions, irrigation layout and drainage requirements.
| Decision | Open-top bag | Standard flat grow bag |
|---|---|---|
| Production format | Individual container-style unit | Horizontal format for row production |
| Plant access | Open from above | Planting positions prepared in the wrapper |
| System review | Confirm support, drainage and emitter position | Confirm gutter, slab dimensions and planting layout |
| Selection basis | Choose from the exact crop, system and quoted product specification—not the format name alone. | |
Who uses Avee open top grow bags
Plant nurseries
Individual bags can reduce the separate pot-filling step and provide a consistent format across a production batch.
Greenhouse vegetables
Tomato, cucumber, pepper and eggplant programmes require an appropriate root-zone volume, blend and drainage arrangement. Confirm these details before ordering.
Soft fruits & berries
Strawberry, blueberry, and raspberry production on elevated benches. Small-format bags may suit elevated strawberry systems; confirm root-zone volume, blend, drainage and irrigation requirements before ordering.
Flowers & ornamentals
Cube-style formats can provide an individual container arrangement for commercial flower production. Confirm dimensions, blend and EC requirements for the crop.
Cannabis & specialty crops
Product selection should be based on the facility’s approved crop programme, sanitation requirements and batch-documentation needs.
Hydroponics & soilless
Compatibility depends on the irrigation system, drainage layout and substrate specification; confirm system fit before ordering.
