Barely enough for one, my friend. You could force 2 in, but you will have issues with overshadowing etc, it's better to LST one and make it fill the space nicely.

Dont forget to LST to make it spread and you would fill a 40x40 with good conditions.

1 in a 15tL pot will fill thae space mate. I just had 2 in a 60x60 and it looked like jumanji was in there.

One plant can fill that space easy. Two will just be too crowded. Fans and humidifiers take up floor space too so things to consider.

Did I need to size up to larger rockwool cubes?Geminated seeds in 1x1x1 rockwool cubes. End state is to be in 5 gallon buckets with 8" net pot and clay pebbles. I figured the roots are too small to reach all the way into water solution still so put small cubes into 4x4x4 rockwool. Did I need to use larger cubes?

Clay pebbles at the bottom I'm thinking using this like maybe an half inch in 4 gallon fabric pot - for better airflow for roots & to prevent overwatering. They absorb the excess well and give off slowly. Been doing this with my normal plants at home and it works well for them. Anyone with experience?
