ok, with opengrow down here a few pics of the light and the first test.
fltr:
- plasma with 100 watt red leds
- plasma
- MH
- HPS
All grows were adjusted to the same initial PPFD at plant height. As you can see 180 watt plasma light (this particular model, the STA-40-02) has about the same ppfd as MH, sodium has much more par light. Then again, the other lights are 250 watt lights, the plasma is a 180 watt light.
Of course the spectrum is a lot different. Also see the shades of the light in the foreground.
