Oh the pressure!

Seriously guys, I'm no expert on anything.
Just another "guy on the internet".
I can offer personal experience, and a little science.

That's why I held off.
I've got to be honest about it.
And the OP is not going to like that.
Hope he can get a refund.

I personally, would not use G8 arrays.

Here are the specs on their "900 Watt" lamp.
Power Draw 540W.
That includes the fans.

Now, that is a lot of led light, but they spread it over 8 bands and that includes worthless IR, and UV.
They withheld information about the wavelengths and their ratios, but I'm guessing they include 720nm. that come on at the same time as the rest of the leds.
Useless when used like that!

An honest 900Watts just might be equivalent to a 1400 W. HPS.
If they used 2 or 4 bands, all in the most efficient frequencies.

Then they want you to purchase an all red, way overpriced UFO, from them in order to flower? WTF?

Sorry Onedog, but I calls 'em the way I sees 'em.
