205W Led grow lights vs HPS 400W

I’m running 205 watt led grow light next to my 400 hps. There’s a piece of corian dividing the closet into two equal spaces. There is a gap the width of the outlet cover where the corian leans against on the back wall. there is a 3" gap at the bottom and a 3 1/2" gap at the top for air flow. Intake’s on one side, air goes past the 400 side and to the LED side then out the top above the LED light. Each is 28"x28". I cleaned the space and gave it a coat of flat white paint.

I have two Sugar Shacks pretty much equal in shape and size the same age, two Sour Diesels about the same in shape and size the same age, and two Chem4s the same age size and shape. Below are pics of everything. I will be putting in a few more plants as I am able, but the comparison is really about these three pairs.
