Mars Hydro II 900W

[TedeBoy]

My first LED grow. 3'x3'x5' space.
I started them under T5 for the first 3 weeks. Now they are at a little over 4 weeks old. Northern Lights and Fast & Vast.
I have the light at 15 to 20 inches from the canopy. Is this about right?
They seem fine but just checking.
Also, do I need to add a UVB bulb or will this Mars by itself be okay?

It draws 411 watts at the wall plug.

It draws 411 watts at the wall plug.

Interesting because the I have did 450w and my 1600 did 671w instead of 780w like Mars stated it would do but still worked good.
