HLG 100 watt Quantum Boards

First post here, starting my second indoor grow and first time with auto flowers. I used only a single HLG 100 in my first photoperiod grow with a short veg in a 31”x31” tent, had low yields so I decided to get a second HLG 100. My question is should I run both through the entire growth cycle or use one for veg and and the second when my autos start to flower. Any advice is appreciated.

Run both full cycle. They'll be perfect. Approx 32W / sqft

Awesome, that’s what I’ll do then. What distance would you suggest hanging them for the seedlings? Both together makes the day time temps around 80 degrees under the light

Approximately 12”. Can to closer is room temperature is low. They are soft on young plants

My room temps are around 70 degrees with an ac on full blast (older mobile home) with both HLG’s running at around 30” above my air temps hit 80 degrees under the light and leaf temps are around 75-78. I think I’ll start it with both at 25”-30” and work it down slowly to as close to 12” without heat stressing them.

Work it down, down, down lol. They are young and those boards are cool. Use what you paid for. U got quality lights, capture as much par as possible!
