About Philips
Why Philips
Philips Greenpower lamps are the ones commercial greenhouses run by the thousand: a high output that holds up over a long life, made to a consistent spectrum. The 315W CMH gives a fuller spectrum than HPS with more light per watt, and runs on its own ballast.
Which lamp
Greenpower HPS in 600W or 1000W on a digital ballast for flowering rooms; the 315W CMH for a single-lamp room or a growth room that wants a natural spectrum. Reflectors and ballasts are under HID Lighting.
Growers' Guides
- Grow Lights for Indoor Plants and Seedlings: Which and How CloseGrow lights for indoor plants and seedlings: do they work, why seedlings go leggy, which light suits a windowsill or greenhouse, and how close to hang it.
- LED or HPS? Why the Best Growers Use BothTom's view from twenty years in the shop: run LED as the main light and add a dimmable HPS, metal halide or CMH for flowering weeks 3-7 for a better finish.
