LED grow lights.

They do say that they are comparable to a 400 watt hps each.

Hello SAP420,

This should have been your first clue that HTG Supply are bullshit artists.

A 90w UFO, no matter who made it or how good it is, will not compare to a 400w HPS.
In fact, your 2 90w LEDs will only come close to competing with 1 400w HPS.

With all that said, I wish you luck growing.
