At just 9.5 watts and 547 mm long, the Flex II 10 is built for propagation. Its low output means you can hang it 15 cm above a tray without burning anything, so it slots neatly into multi-layer rack systems where headroom is tight.
The balance of red and far-red light pushes root formation, which is exactly what germinating seeds, sprouts and microgreens need. We also reach for it when pre-growing young plants before they move to a bigger light. It is IP68 sealed against splashes and carries a 3 year warranty.
