Pro Tips

Swap out your Metal Halide for an HPS when you flip to flower for maximum yields. The 400W is perfect for small to mid-sized tents, while the 600W version is built for more serious setups that need deeper canopy penetration.

The Hortiking Metal Halide Lamp is simple, tough, and still one of the best ways to grow compact, healthy plants the natural way—no stretch, no drama, just solid results.
