A 6x12 germination kit with LED grow light bars
This is the larger LED-and-dome kit, skipping the heat mat and built on the 6x12 tray. Two Samsung LM301H EVO LED bars light the whole tray evenly and run on a four-level timer that cycles daily. The rigid 3mm dome seals in humidity for germination, and its rotating vents open up as clones root and need to harden off. Growers keep the bars a few inches over a full 6x12 tray so every cell gets the same light.
Running the humidity dome germination kit at scale
The 6x12 tray holds up to 72 cells, so it fits bigger seed runs and larger clone batches. With no mat in the box, it works best where the room already holds seedling temperatures. Cool rooms may want bottom heat. In that case, the seedling-mat version adds a far-infrared mat to this same 6x12 setup.
