Steering-grade coco slabs and grow bags for greenhouse pepper and high-wire cucumber production. Leamington and Kingsville, BC and Alberta, the US Midwest and Sun Belt, and Mexico's protected-agriculture export sector. Washed low-EC, pre-buffered, blended for the dryback control peppers demand and the root-zone oxygen cucumbers can't live without. Lab-tested, stocked one hour from Leamington in Cambridge, Ontario.
"We run bell peppers on a V-system in Kingsville and moved two bays from rockwool to Avee coco slabs as a trial. Generative steering took a little recalibration, but the buffer against our fertigation hiccups is real — and at teardown we composted the slabs instead of paying to landfill rockwool. The whole range is on coco next season."
"High-wire cucumbers are brutal on a substrate — three crops a year, heavy irrigation, and Pythium waiting for any waterlogged slab. Avee's chip-blend slabs kept the root zone oxygenated through summer, and the second crop went into the same slabs after a flush with zero issues. Delivery from Ontario cleared customs without us touching the paperwork."
"Our protected pepper program in Querétaro exports year-round to the US, so substrate consistency isn't optional. Every Avee batch arrived with the lab sheet, the washed EC matched it, and the slabs wet up evenly across the house. That predictability is why we standardised on them for the new hectares."
The Leamington–Kingsville belt in Essex County holds the densest concentration of greenhouses in North America, and Ontario's roughly 4,000 acres of protected vegetables are dominated by three crops: tomatoes, peppers, and cucumbers. Every one of those acres grows in soilless slabs on drip fertigation — and the substrate decision is made per crop cycle, every cycle.
Rockwool built this industry, but coco coir is winning the re-order. Coco slabs deliver the same steering precision with a cation buffer that forgives fertigation faults, reuse across 2–3 cucumber crops in a year, and end-of-crop disposal that means composting — not paying landfill fees for synthetic fibre. The same shift is running through Michigan and Ohio's new builds and through Mexico's export houses in Sinaloa and Querétaro, where coco is already the default.

Peppers are a steered crop — growers push vegetative or generative balance through controlled drybacks and feed EC of roughly 2.5–3.5 mS/cm. That takes a slab with predictable, uniform dry-down behaviour. Cucumbers are a speed crop — 2–3 plantings a year under heavy irrigation, where the killer is a waterlogged, oxygen-starved root zone and the Pythium that follows it.
One generic slab does not serve both. Avee blends the pith:chip ratio per crop — a balanced steering blend for peppers, a chip-forward high-porosity blend for cucumbers — washed low-EC, calcium pre-buffered, and lab-documented per batch so the slab behaves the same in bay one and bay forty.
We supply pepper and cucumber operations at every scale — from the Leamington belt an hour from our warehouse, to US Midwest and Sun Belt builds, to Mexico's export programs where coco is already the standard.
The densest greenhouse cluster in North America sits one hour from our Cambridge warehouse. Leamington and Kingsville pepper and cucumber operations get the fastest slab resupply in the industry — 24 to 48 hour delivery windows, crop-specific blend ratios, and lab sheets with every batch. No container schedules, no offshore lead-time gambles mid-crop.
Delta and the Fraser Valley anchor BC's pepper houses, Alberta's Medicine Hat cluster grows cucumbers and peppers under some of Canada's sunniest skies, and Quebec's greenhouse expansion is adding vegetable acreage yearly. Avee ships coast to coast from Ontario with rail and road freight — full pallets to full truckloads.
Michigan and Ohio host the fastest-growing greenhouse vegetable builds in the US — many run by the same operators expanding out of Leamington — while Texas, Arizona, and California grow peppers and cucumbers year-round under glass and shade. Avee ships cross-border from Ontario with full customs documentation handled end to end.
Mexico is the top supplier of fresh peppers and cucumbers to the US market, grown across a vast protected-agriculture sector in Sinaloa, Sonora, Querétaro, and San Luis Potosí — where coco slabs are already the default substrate. Avee is expanding freight lanes into Mexico and quotes factory-direct container loads for large programs. Contact us to confirm availability for your region.
Whether you run a V-system pepper house in Kingsville, high-wire cucumbers in Ohio, shade-house production in Sinaloa, or you're planning a switch off rockwool — Avee blends the slab to the system.
Greenhouse bell peppers grow on a V-system — typically three plants per slab, each double-stemmed to six productive heads, trained up twine over a 10–11 month crop. Peppers are heavily steered: growers push vegetative or generative balance through dryback depth and feed EC, which demands a slab with uniform, repeatable dry-down. Avee's balanced pepper blend delivers consistent steering response bay after bay, with the cation buffer rockwool can't offer when fertigation stumbles.
Cucumbers are the sprint crop of the greenhouse — 2 to 3 plantings a year under heavy irrigation, on high-wire or umbrella training. The root zone risk is oxygen starvation: waterlogged slabs invite Pythium and collapse a planting in weeks. Avee's chip-forward cucumber blend holds high air-filled porosity under intensive drip cycles, then flushes and replants for the next crop — the same slabs running multiple cycles per year.
Mexico's export peppers and cucumbers grow across shade houses, macro-tunnels, and glasshouses — a protected-agriculture sector built around coco slabs and open-top bags from the start. Compressed coco ships dense to remote production zones and hydrates on site, and Avee supplies export-grade batches with the documentation year-round US-bound programs require.
Most established pepper and cucumber houses grew up on rockwool — and the switch to coco is usually driven by three things: a root-zone buffer that forgives EC and pH excursions instead of amplifying them, slab reuse across cucumber cycles, and disposal. Spent rockwool is synthetic waste with real landfill costs; spent coco composts or spreads to field. Steering in coco takes a short recalibration — slightly deeper drybacks to hit the same generative signal — and Avee supports the transition with blend specs and trial-bay quantities.
Every parameter that matters for commercial pepper and cucumber production — with the values Leamington, US, and Mexico operations require.
← Swipe for full table| Parameter | Avee Pepper & Cucumber Blends | Why It Matters for These Crops |
|---|---|---|
| Blend Ratio | Per-crop — balanced for peppers, chip-forward for cucumbers | Peppers steer best on a balanced pith:chip slab with uniform dry-down. Cucumbers under heavy irrigation need a coarser, higher-porosity blend to keep roots oxygenated. One generic slab compromises both — Avee blends to the crop and documents the ratio. |
| Starting EC | Washed low-EC (lab-tested) | Slabs must arrive clean so your feed program — not residual salts — sets the root zone. Every Avee batch is washed and lab-verified before dispatch from Cambridge, Ontario. |
| Feed EC Range | Peppers ~2.5–3.5 · Cucumbers ~1.8–2.8 mS/cm | Peppers run hotter feed and are steered through EC and dryback; cucumbers run leaner and faster. Coco's cation exchange buffers both programs against injector faults that would hit an inert slab at full strength. |
| pH Range | 5.5 – 6.5 (stabilised) | Both crops feed at pH 5.5–6.0 in the root zone. Coco arrives in range and holds it — no lime conditioning period, plant on delivery. |
| Pre-Buffered | Calcium pre-buffered at source | Raw coco exchanges sodium and potassium for the calcium in your feed — a direct route to blossom-end rot in peppers. Avee slabs are buffered at processing, so the exchange is already done before the crop meets the slab. |
| Slab Format | 1m slabs, ~20–25L expanded (custom sizes available) | Standard greenhouse gutters take 1-metre slabs at 3 pepper plants or 2–3 cucumber plants per slab, one dripper per plant minimum. Custom lengths and volumes for non-standard gutters on request. |
| Air-Filled Porosity | High — chip fraction engineered per crop | Cucumber root zones fail from oxygen starvation before anything else; Pythium follows waterlogging. The chip-forward cucumber blend keeps AFP high through 2–3 intensive crop cycles per year. |
| Reuse Cycles | 2–3 crops per slab (cucumbers) | Flush between plantings, verify drain EC, replant. Multi-cycle reuse cuts substrate cost per crop dramatically versus single-use rockwool — a structural cost advantage for high-turnover cucumber programs. |
| End-of-Crop Disposal | Compost or spread to field — $0 landfill | Spent coco is organic matter; spent rockwool is synthetic waste with hauling and landfill fees. Across a large Leamington range, disposal alone can justify the switch. |
The complete setup workflow for commercial pepper and cucumber operations in Canada, the USA, and Mexico — with the crop-specific details that matter at the root zone level.
Rockwool built the greenhouse vegetable industry, and it steers beautifully — that's the honest starting point. Here is where coco matches it, where coco wins, and why re-orders across the Leamington belt keep shifting to coir.

A balanced pith:chip steering blend. Peppers are steered vegetative or generative through dryback depth and feed EC, which demands a slab with uniform, repeatable dry-down behaviour — enough pith for stable water holding, enough chip for drainage and re-wetting. Avee blends pepper slabs to this profile, documents the ratio on every batch sheet, and supplies custom ratios where your climate or irrigation strategy calls for it.
Chip-forward and high-porosity. Cucumbers run 2–3 crops a year under heavy irrigation, and the failure mode is a waterlogged, oxygen-starved root zone followed by Pythium. A coarser chip fraction keeps air-filled porosity high through intensive summer drip cycles and holds its structure across multiple plantings in the same slab.
Typical programs run peppers at roughly 2.5–3.5 mS/cm feed EC and cucumbers leaner at roughly 1.8–2.8 mS/cm, adjusted for light, stage, and steering strategy. Coco's cation exchange buffers both programs against injector faults — an EC spike that would hit roots at full strength in an inert slab is partially absorbed by the coir. Monitor drain EC weekly and adjust drain percentage to prevent accumulation.
Standard practice on 1-metre slabs: 3 pepper plants per slab, each double-stemmed to give 6 productive heads, or 2–3 cucumber plants per slab depending on variety and training system. Run at least one pressure-compensating dripper per plant. Send us your gutter spec and target stem density and we'll size slabs and volumes to match.
Yes — with a short recalibration. Coco holds more readily available water than rockwool at the same volumetric reading, so growers typically run slightly deeper drybacks to land the same generative signal. Once dialled in with substrate sensors over the first weeks, steering response is uniform and repeatable — and you gain a root-zone buffer against fertigation faults that rockwool cannot offer. We recommend starting with trial bays, and Avee supplies trial quantities with full blend specs.
Yes — this is one of coco's structural cost advantages. Between plantings: remove root mass, flush the slabs until drain EC returns to baseline, verify, and replant. The same coco slabs typically run 2–3 cucumber crops per year, where rockwool is generally single-crop. Costed per crop cycle rather than per slab, coco changes the substrate line in your budget.
