Yield difference compared to 1000w - 600w hps?
Thanks in advance
Just had a look at the spectrum of the 630, it looks pretty bloody good. Maybe a bit high in the green and yellow meaning wasted par, not enough to worry about, however it's the UV down to 380 that is impressive, provides just that little bit of stress just where you want it.
If you're not totally set on HPS, it's worth having a look at https://chilledgrowlights.com especially their kits. You won't have any wasted par, hand made to order.
