Even light from edge to edge
One hot spot leaves the edges of a tent stretched and slow. Slim bars spread across the frame light the corners evenly and run close without scorching.

- Hang kits from the tent frame with the rope ratchets.
- Plug the bars into the power supply, then the supply into the mains.
- Run about 15cm above the plants (20cm for the 200W Kit); raise if plants show stress.
