How bigs your mini split? I'm not a fan of air cooled hoods when cooling the room, if your aircon can keep up, get rid of the glass on your reflectors and you will get alot more light, raise shades for bigger footprint, and use more or your room.

Hmmmm same size split as I was running before. When you add in dehumidifier your AC may struggle without air cooling your lights so it may be needed... You running CO2? You need CO2 in sealed room.

The 4 spread out is def the way to go. You will actually want them closer to the walls then making them dead center, assuming you want to light the entire space. Key is having no hotspot in the middle of the 4. .

It would be more helpful if you posted pics of your plants. If I had to guess I’d say your not filling the room as full as it needs to be and or something else is going on since your only pulling .75 lbs per 1k light.

That helps. You need to think about and share how you want the space to work.

It looks like your current setup is a dream as far as access. Easy access, top, bottom, all sides. It solves every problem we all hate as far as getting around the plants.

But as you say it does not max them out.

1st...grow style, veg length and your ability to SCROG should make it so each plant is 8oz dry harvest roughly (some more, some less). If they aren't, you have room to improve the veg part of your growing.

2nd...you need to redesign the 12x12 space to fit more plants and still allow good access. Are you considering a separate veg area or one big room that goes full cycle? If one big room, it's just a matter of layout. If you have a light meter, you should spend some time measuring your current layout.

Because you put the 4 fixtures right next to each other, there are much brighter spots and hotter spots where the lights meet, especially the center area.

My first goal would be to understand at your growing height how wide each lights quality growing perimeter is. And space the lights out to make one much bigger growing area or a few separate ones. Likely either a big grow space in the middle, more square shaped, or 2 rows of growing that are not linked for light. It really depends how you want to access it and how easy access should be.

I do have a separate veg room with 10 plants that are ready to load in this room as soon as these come down. I was trying to get it where this room comes down every 10 weeks and gets re-loaded from the veg room

It just seems like I am limited to 8 to 10 plants at a time and no matter how many I do I always pull the same

I would guess you just need to space the lights out more to provide more grow area and add a few plants. If yield is lower than expected, strains matter the most, then consider vegging another week or 2 and it should be a bigger harvest.
