8. Apollo Horticulture 1000 W HPS Bulb
This HPS bulb is a pro-level light for indoor growers.
The Price
The Good
This bulb was designed specifically for professional hydroponic growing, which means it has more than enough power to get your plants moving into the flowering phase.
The Bad
As with a few others on our list, this is just the bulb. But if you’ve already got a HID setup, then this is a great choice for your next HPS bulb.
