Can I use a 600w lamp with a 400w ballast?2017-06-16T09:07:16+01:00

No. Unfortunately the wattage of the lamp must correspond to the wattage of the ballast in every case. You can’t use a lamp of higher 0R lower wattage than the ballast because the ballast is designed to drive a lamp with exactly those electrical characteristics.

What is the difference between High Pressure Sodium (HPS) and Metal Halide (MH) lamps?2017-06-15T17:59:31+01:00

The difference is the spectrum emitted. HPS emits light that uses more of the orange and red side of the spectrum, perfect for plants in bloom stage. MH emits more of a blue green spectrum which is great for plants in growth stage.
