AC Infinity Propagation
Seeds and cuttings need three things before they need anything else: steady warmth at the root zone, high humidity around the leaves, and gentle light that does not cook them. This collection is AC Infinity's propagation range built around exactly those three jobs — Suncore seedling heat mats, humidity domes in two sizes, Ionbeam LED bars sized to sit over them, and a dedicated propagation tent to house the lot. Quick Bloom Lights is the official Australian importer: stocked in Sydney, shipped domestically, warranty handled here.

Match the light to the dome
The Ionbeam bars and the humidity domes are sized to go together. Each Ionbeam kit is four bars and one dimming schedule controller, and the bars mount magnetically or with the included screws, so they sit over a dome, on a shelf in the propagation tent, or along a tent frame later as side lighting once the plants move up.
| Dome | Tray | Footprint | Light that fits |
|---|---|---|---|
| Humidity Dome | 5×8, 40 cells | 36 cm long, height extension included | Ionbeam S11 — 28 cm bars, 30 W |
| Humidity Dome XL | 6×12, 72 cells | 53.3 × 27.4 cm, height extension included | Ionbeam S16 — 40.7 cm bars, 42 W |
Seedlings and fresh cuttings do not want full flowering light. Run the Ionbeam on its lower dimming levels to start and raise it as the plants harden off — ten levels gives you room to do that gradually rather than jumping from nothing to everything. Both kits have a UIS port, so an AC Infinity controller can put the light on the same schedule as the rest of your setup.
Heat mats: warmth from underneath
Most seeds germinate faster and more evenly with a warm root zone, and cuttings root faster when the medium is warmer than the air. The Suncore heat mat uses far-infrared film rather than wire coils, so heat spreads evenly without hot spots that scorch seed, and it comes with a digital controller where you set an exact temperature instead of guessing with a dial. The mat is IP-67 sealed, including the cord connection, so drips and spills from the tray are not a problem, and it ships with an Australian 240 V plug.
Straight answer on heat mats: a heat mat adds warmth on top of the room — it lifts the surface by roughly 5–11°C, not to any number you choose. In a 22°C room it will hold 27–30°C at the tray without effort. In a 10°C garage in July it will not reach 28°C, whatever the controller is set to. If the room itself is cold, sit the dome inside a propagation tent or move it somewhere warmer first.
Humidity domes: hold moisture, then let it go
A cutting has no roots to replace the water it loses through its leaves, so for the first days it needs air close to saturation. The domes lock that humidity in, and the adjustable vents are what let you wean the plants off it — closed for the first few days, then opened a little more each day as roots form or seedlings put on true leaves. That gradual venting is what stops plants collapsing when they come out of the dome. The height extension lifts the lid for taller cuttings or seedlings that outgrow the standard dome.
For cloning in hydroponic systems, clone collars and mesh net cups in 2″, 3″ and 4″ hold cuttings in place and let roots grow straight through into the reservoir.
A propagation tent for more than one tray
The Cloudlab Advance Propagation Tent is 60 × 60 × 90 cm and runs standing up or on its side. With the included shelves and bars it takes up to five humidity domes across multiple tiers, has three 100 mm (4″) duct ports and a controller mount, and ships with waterproof catch trays for the floor. It is the step up when one dome on a bench is no longer enough, and it gives the heat mats a warmer, closed space to work in.
Germinating a few seeds at a time? For small batches — a handful of seeds rather than a full tray — our Seed Starter range is the better fit: the Sprout germinator and Heat Pack hold seeds at 27°C on USB-C power, with no mat or dome needed.
FAQ
Do I need all three — mat, dome and light?
For cuttings, yes: they need humidity from the dome, warmth to root, and some light to keep photosynthesising. For seeds, the mat and dome do most of the work until they break the surface, and the light matters from the moment they do. Seedlings that come up without enough light stretch and fall over, and that is hard to undo.
What temperature should I set the heat mat to?
Mid-20s°C at the medium suits most seeds and cuttings, and around 26–28°C is a good starting point for faster germination. Measure at the tray, not the air — the controller shows the mat's own temperature, and the medium sitting on it will read a little lower.
Can I use a heat mat inside a grow tent?
Yes. It draws very little power and the IP-67 sealing handles a humid space. Keep it under the tray, not under fabric pots or anything that insulates the top surface, and turn it off once seedlings are established — plants past propagation do not need root-zone heat.
How high should the Ionbeam sit above seedlings?
Over a dome, the bars sit on or just above the lid. Start on a low dimming level and increase it over a week or two. If seedlings stretch, lower the light or raise the level; if leaves bleach or curl, raise the light or lower the level.
Can the Ionbeam bars be used for anything after propagation?
Yes, and that is a large part of their value. The same bars mount magnetically to a grow tent frame as side or under-canopy lighting once plants are in a bigger space, so they are not a one-season purchase.
Is this genuine AC Infinity stock with Australian warranty?
Yes. Quick Bloom Lights is the official Australian importer and distributor for AC Infinity. Stock is held in Sydney, orders ship domestically, powered units come with an Australian plug, and warranty is handled here rather than through an overseas seller.
