  1. are there different types or styles of hps lights? will they all work for growing grass plants?
  2. if it says its hps it should work
  3. There's normal hps which has little or no blue light. These lights are fine for use just in the flowering stage. However, there's also the son agro type which are designed to give blue out too and those can be used in the vegative stage too.

    I just got me a 400W Philips Son T Agro HPS and my babies went from 6-7inches to 10-12inches (with lots of undergrowth too) in 5 days. You can see the pics in my thread: Newbie grower with height problem. I had used six fluoros for a month to get mine to six inches. 5 days under the HPS doubled their height!!! Fluoros work but hps kicks ass!!

    Good growin' to ya!
