Surna

What Surna does

Surna Inc. (OTCQB: SRNA), headquartered in Louisville, Colorado and founded in 2006, designs, manufactures, and supports precision environmental control systems (HVACD — Heating, Ventilation, Air Conditioning, and Dehumidification) for indoor horticulture and controlled environment agriculture (CEA), with a primary focus on the regulated cannabis industry. Its product portfolio centers on the proprietary SentryIQ Grow Room Controller, which applies predictive algorithms for temperature, humidity, and VPD management, and is complemented by EcoChill chillers (including a Trane-co-branded industrial chiller and heat recovery variants), EnviroPro air handlers, Isostream fan coils (including GMP-compliant and cassette/wall-mounted models), VRF systems, Anden-branded dehumidifiers and steam humidifiers, a Destrat ventilator, and distributed TrolMaster control systems. The company has extended beyond core HVACD into Neocision LED horticultural lighting, water treatment (filtration, RO, UV, condensate reclamation, storage), CleanLeaf HEPA filtration, Air Sniper air sanitization, benches and racks including StrataAir racking for tiered airflow, and licensed MEP engineering and architectural design services, positioning itself as a one-stop-shop for facility design and equipment.

Surna's revenue model is primarily hardware sales (HVACD, controls, LED, water, air purification) supplemented by professional services — MEP engineering, installation support, preventative maintenance, and local troubleshooting — with customer financing facilitated through third-party partners Leasing Innovations and Cultivation Technology Finance Group (CTFG). The company operates a sales-led, enterprise field motion with dedicated project managers guiding customers from facility design through system commissioning, supported by content marketing (blog, white papers, webinars, case studies), trade show presence (Indoor Ag-Con), and an active social footprint. It serves primarily commercial indoor growers — multi-facility cannabis operators, vertical farms, and greenhouse-based CEA businesses — across the U.S., Canada, and Panama, claiming 800+ cultivators served and 200+ commercial projects completed since 2006. Capital structure is public on the OTCQB exchange; the investor relations page is hosted at ir.ceaindustries.com, suggesting a corporate linkage to CEA Industries, though no explicit parent-subsidiary relationship is disclosed.

Expansion highlights5 records

Direct peers

• Urban-gro: Urban-gro is a direct competitor providing integrated CEA systems engineering, equipment, and consulting for cannabis and horticulture facilities. Its full-service project approach from design through cultivation technology closely mirrors Surna's go-to-market.
• Climate Control Systems Inc. Climate Control Systems designs and manufactures HVAC and environmental control packages specifically for indoor cannabis cultivation. Its dehumidification and climate-system portfolio competes head-on with Surna's EcoChill, EnviroPro and Isostream lines.
• Quest Dehumidifiers: Quest (a Therma-Stor brand) manufactures commercial-grade dehumidifiers widely specified for cannabis and CEA grow rooms. Its dehumidification line competes directly with Surna's Anden-branded offerings and other cultivation-targeted humidity equipment.
• Atlas Greenhouse & Manufacturing: Atlas designs and manufactures greenhouses and environmental control systems for horticulture, including cannabis. Its integrated structure and HVAC offerings overlap Surna's CEA facility design and equipment bundle.
• Conviron: Conviron designs and manufactures controlled-environment chambers and HVAC systems for plant research, greenhouse, and indoor agriculture. Its chamber-based environmental control platform is comparable to Surna's CEA-focused HVACD solutions.

Broad incumbents

• Hydrofarm Holdings Group: Hydrofarm is a publicly-traded, broad-line distributor and manufacturer of CEA equipment including lighting, fans, and environmental controls. It sells to the same indoor-grower customer base as Surna via a much wider SKU catalog and distribution scale.
• Hawthorne Gardening Company: Hawthorne, a division of The Scotts Miracle-Gro Company, offers horticulture lighting, climate, and nutrient products for cannabis and CEA. Its broad HVACD-adjacent product footprint puts it in competition with multiple Surna sub-brands.

Emerging players

• Agritecture: Agritecture is a CEA consulting and software firm that designs vertical farms and indoor agriculture facilities. It overlaps Surna on facility-design and planning services (the two companies are documented partners), and competes for the design-of-record role on new builds.
• TrolMaster Controls: TrolMaster makes climate, irrigation, and CO2 controllers used by cannabis and CEA growers. Surna distributes TrolMaster, but TrolMaster's standalone controller products compete with Surna's proprietary SentryIQ Grow Room Controller in the same grow rooms.
• Anden: Anden manufactures high-capacity commercial dehumidifiers targeted at cannabis cultivation. Its SKUs are carried by Surna as a partner product but also sold direct, making it a partial competitor in humidity control.
