Athena VPDome Rack Cover | Fits 48 x 72 x 16 in Wire Racks

What the Athena VP Dome Replaces on a Propagation Rack

Sixteen clone trays on a rack normally means sixteen plastic domes, each with its own microclimate. The VPDome throws all of them out and covers the whole rack instead. It is a fabric cover rather than a tent frame. The rack it fits is a standard wire unit at 48 in wide, 72 in high and 16 in deep. A bottom rack cover comes with it, and the door closes on magnetic seals. The rack itself is not included, which the photography does not make obvious. Packed, the cover is 4.5 by 23.5 by 9.5 in and weighs 8.2 oz. The fabric carries an anti-microbial coating on the material itself. Labour savings run two to four hours per rack per month, which comes from not lifting domes. Installation is three steps and takes one person a few minutes. Bottom cover down, main cover over the top, magnetic door closed. Durable fabric replaces a stack of thin plastic domes that crack and get binned every cycle.

Why Uniform Vapor Pressure Deficit Roots Faster Than a Tray Dome

Vapor pressure deficit, not humidity alone, decides how hard a cutting has to work to hold water. A cutting with no roots cannot replace what it loses, so the air around it has to do the holding. Individual domes each drift, because each one vents differently and each sits at a different height. One enclosure over the whole rack gives every tray the same air. Uniform conditions are why rooting evens out and why mortality drops, rather than any single number being lower. The practical gain shows up at transplant, when a whole rack is ready on the same day. Run it over a wire rack with a small fan and a humidifier outside the cover. The fabric is not rigid, so it will sag if the rack is overloaded or out of square. It also blocks light, so shelf lighting goes inside the cover rather than above it. Anyone running a single tray at a time gets nothing from this, and it earns its keep on a full rack.
