Growy Past 600 Jumbo Stores: Vertical Lettuce at Scale

Indoor greens just cleared another retail milestone in the Netherlands. In a September 24, 2026 interview published by Vertical Farm Daily, Growy co-founder Laura van de Kreeke said the Amsterdam-area vertical farm now reaches more than 600 Jumbo stores—more than 100 locations beyond the 500-store mark it hit five months earlier—and has joined Jumbo Online for the first time.

What is on the shelf

The range is now three SKUs: Knapperige Sla (Crispy Lettuce), Frisse Sla (Fresh Lettuce), and Lekker Pittig (Nice and Spicy), up from two SKUs at the April national launch. Knapperige Sla and Frisse Sla are listed on Jumbo’s online platform; Lekker Pittig remains stores-only for now. Laura ties the online step to nationwide supply consistency—Jumbo Online was not possible on day one of the brick-and-mortar rollout.

• Retail footprint: 600+ Jumbo stores (from ~500 five months earlier)
• SKUs: three lettuce lines in almost all national Jumbo locations
• Online: two SKUs on Jumbo Online
• Next: additional unnamed retailers “very soon”

Why it matters for vertical farming

Growy frames the expansion as proof that vertical farming can deliver at supermarket scale—pesticide-free greens in everyday grocery channels—not only specialty boxes. No yield-per-m² or consumer price figures are published in the piece; do not invent them.

What “supermarket scale” does and does not mean

Growy’s claim is distribution breadth inside one national banner, not a global vertical-farm boom. The interview does not disclose farm footprint, energy use per kilogram, or shelf price versus imported field lettuce. What it does show is operational maturity: enough consistent volume to feed 600+ stores and clear Jumbo’s online supply bar. Laura also says more retailers are coming without naming them—treat that as intent, not a signed rollout calendar.

Five months from 500 to 600+ stores is a fast retail cadence for a controlled-environment grower. The third SKU (Lekker Pittig) shows Growy iterating assortment, not only square meters. Online listing for two SKUs is operationally harder than a single banner planogram because fulfillment must stay nationwide-consistent—Laura’s stated gate for Jumbo Online.
