Athena VPDome

What the VPDome Is

The Athena VPDome is a full-rack fabric enclosure — not an individual tray dome — engineered to wrap a standard 48"W × 72"H × 18"D wire shelving unit and create a single, stable microclimate across all shelves simultaneously. It holds up to 16 standard 10×20 clone trays per rack without requiring a separate plastic dome over each tray.

Construction is durable nylon fabric with an antimicrobial coating applied to reduce pathogen and disease pressure in the propagation environment. Access panels feature transparent, zippered doors so staff can observe and check cuttings without fully breaking the seal, and magnetic closures keep the enclosure tight between checks. Cord insert slots and built-in thermometer holders allow probes, sensors, and environmental monitoring gear to run through cleanly without compromising humidity retention.

Who This Is For

Any licensed cannabis or hemp operation running a dedicated clone room or propagation bay will see immediate workflow benefit. If your nursery team is managing individual plastic domes across multiple racks — lifting, venting, misting, and re-sealing each one on a rotation — the VPDome consolidates that into a single enclosure per rack. Athena developed this in a high-production nursery setting where labor efficiency and repeatable results are non-negotiable.

It is particularly relevant for multi-license operators, vertically integrated cultivators, and production facilities where consistent clone rooting rates and low mortality directly affect throughput downstream in veg and flower. Operations running Athena's broader Culture Line — including Cuts rooting gel and Reset sanitation — will find the VPDome integrates naturally into that existing SOPs.

Key Features and Design Details

The core performance argument is VPD uniformity: instead of 16 individual microclimates that drift depending on how recently each dome was vented or re-sealed, the VPDome creates one shared environment across the full rack. Athena's published clone room parameters target 70–80°F ambient temp and 65–75% RH, producing a VPD of approximately 0.8–1.0 kPa — the range where cuttings transpire minimally and root initiation is fastest.

Reusable construction is a direct cost offset against recurring plastic dome spend. The antimicrobial fabric coating addresses one of the most common propagation failure modes: pathogen buildup between cycles. Athena's own procedure recommends sanitizing the VPDome with a sanitation agent before every clone cycle. Cable slots support clean integration with temperature/RH probes, heat mats, or any environmental sensor a facility is already running. Setup is three steps: install the bottom shelf cover, place the main cover over the rack top, close the magnetic-seal door.

How It Fits a Commercial Build

The VPDome is SKU TC-VPD within the Athena Culture Line — the same product family that covers propagation through tissue culture. The rack cover is sized for the industry-standard 48"W × 72"H × 18"D wire shelving unit common in commercial nursery builds, so it slots into existing infrastructure without a dedicated shelf purchase in most facilities.

Labor savings are the clearest operational metric: Athena cites 2–4 hours per rack per month compared to individual dome management. For a clone room running four to six racks, that is a meaningful reduction in repetitive handling. For operators planning new builds, retrofits, or expansion of propagation capacity, the VPDome pairs with rolling or vertical racking to maximize the number of productive racks per square foot of dedicated propagation space.
