How the Green Pad Jr CO2 Generator Starts Working
Nothing gets switched on. The pad reacts with humidity in the air, and roughly 35% RH is enough to begin the release. A propagation dome sits far above that, which is why the pad and the dome suit each other. Sealed in the bag the pads stay dormant, so the other nine in the pack keep until you need them. Misting a pad lightly speeds the start if you want it running sooner.
Why CO2 Pads Belong in a Dome and Not a Tent
Scale is the whole answer. This is the Jr, sized for the enclosed volume under a clone dome rather than a whole room. Inside that small sealed space a measured release lifts the concentration quickly. The same pad in a 4x4 tent would be lost. Cuttings are the case that benefits most here. A cutting has no roots yet, so it takes everything it gets through its leaves. Raising CO2 around those leaves supports the rooting process, which is why growers reach for co2 pads at propagation specifically. Use one pad at a time and replace it every other day until roots appear or the dome comes off. Reseal the pack between uses. Two honest limits. The release is measured rather than controlled, so pair it with a meter if you want to know your number rather than assume it. And a dome that gets opened every few minutes vents whatever the pad has just built up inside it.
Key Features
- Humidity activated, no equipment: Around 35% RH starts the reaction. A propagation dome is well past that on its own.
- Sized for a clone dome: The Jr covers the enclosed volume under a dome, where a room-sized pad would be wasted.
- Ten pads per pack: One pad at a time, replaced every other day until rooting finishes.
- Unused pads stay dormant: Reseal the package and the rest of the pack waits until it is needed.
- Aimed at cuttings and seedlings: A cutting with no roots yet feeds through its leaves, which is where CO2 helps most.
- Odorless and passive: No tank, no burner, no ballast, and nothing to plug in or vent.
