Coco Coir Grow Slabs for Tomatoes in Leamington Greenhouses
High-wire tomato production in Leamington typically runs from January seedling through to November or December — a 10-to-11-month root-zone commitment on a single substrate. Coco coir grow slabs with a 70/30 pith-to-chip blend provide even moisture distribution across the full slab length, reducing blossom-end rot incidence and supporting consistent fruit set through the long production cycle.
Unlike rockwool, which provides no cation exchange capacity, coir's natural buffering allows growers finer control over root-zone EC between irrigation events — a critical advantage in precision crop steering programs running across Essex County operations.
Coco Coir for Cucumber and Pepper Operations in Essex County
Cucumber crops in Leamington demand a substrate that keeps pace with extremely high summer transpiration rates while draining quickly enough to prevent root suffocation. A 50/50 pith-to-chip coir slab delivers the balance: high water retention through the vegetative phase and sufficient AFP to prevent waterlogging under aggressive summer irrigation schedules.
For pepper operations running into late autumn, we recommend a chip-augmented slab — adding coarse husk chips increases drainage capacity as root systems mature and irrigation volumes reduce heading into September and October.
Switching from Rockwool to Coco Coir in Ontario Greenhouses
The transition from rockwool to coco coir is the most common substrate change happening in Leamington operations today. The drivers are both economic and regulatory. Rockwool disposal represents a meaningful end-of-season cost — inert mineral fibre requires landfill, and those fees are rising. Quality coco coir slabs, properly maintained using an enzyme protocol between crops, can deliver two to three seasons of use before replacement.
Across a large operation, the difference in annual substrate cost per acre is substantial. Beyond cost, biodegradable coir supports sustainability reporting increasingly relevant to major retail and foodservice customers in Canada and the United States.
