5x mk ultra
All from seeds and Ill divide them under my lights.
I plan on having NO exhust NO intake and NO filters...
1.2 x1.2 Growing beds of 150 liter of coco under each light.

I dont think you will have a probleem from helicopters if you can keep your grow room cool enough.
My last run was 5x 600w in cool tubes with no insulation what so ever and helicopter was flying over my home almost everyday!
My grow room was 24c max tho!
My only concern is how you are going to vent the ac units heat !
Where I am planning on starting my next grow they dont have flir heli
So hopefully it will be alittle safer!
