Tent 6x12x8

I am going to be running 2 1000 watts off of this, but i would like to add a third have 1000 per 4ft of space any issues you guys think i might run into i have a mini split, but am just worried that i would do more harm and want to see what you guys think?

it all depends on your ambient temp that get pulled into the tent and how much exhaust you have getting rid of hot air. Definitly can run a 3rd 1k just need the right setup.

How much btu's A/C u going to use to cool that shit down?

I won't be exhausting any air i want a completely sealed room and the Minisplit is 12000 BTU i know that is 4kbtu per 1k watts, but i don't know if I'm cutting it to close i will have my co2 dehumidifier my six circulating fans as well as can 150 filter in there i mapped it out for only 2 1k lights, but if i can add a third i would not mind i just want to maximize my space to its full potential without doing harm
