Propagation tents and kits cover the first two to three weeks of a grow, when the plant has no root system and cannot regulate itself. What it needs is warmth, high humidity and gentle light – conditions a flowering tent is actively bad at providing.
Tent, propagator, or both?
A heated propagator – tray, humidity dome and a heat mat – is enough for a windowsill batch of seeds or a few cuttings. Cheapest route in.
A propagation tent is short and shallow, holds several trays, and lets you control light and humidity independently of the room. See propagation tents for the tents on their own.
A complete kit pairs the two with a low-wattage light and a timer, which is what most people actually want if they are starting from nothing.
What matters at this stage
Bottom heat. Roots form on temperature, not light. A heat mat under the tray is the single highest-impact thing you can buy.
Humidity near saturation. Cuttings have no roots and lose water through their leaves. A dome or a sealed tent keeps them alive until they root.
Low light. A cutting cannot use a 600W fixture. A small LED or a fluorescent bar at distance is correct.
Short heights. Propagation tents are deliberately shallow so the light sits close and the volume stays warm and humid.
Moving them on
Once rooted, cuttings go into a veg space and then to flower. A small grow tent makes a good intermediate step, or straight into a 1.2m tent. Running propagation permanently alongside flowering in one footprint is what grow tents with shelves are for.
