how tall are miners ? and are they 1 shelf high? or 2 shelves or 3 or 4?
There are no miners there yet, I can place them how I want , I am thinking 4 rows , 10 miners each
thinking about leaving 3 feet from ground, than place the first row , each row will be 1.64 feet , so here is how it should look
Roof
3.44 feet space
row> 10 miners
row> 10 miners
row> 10 miners
row > 10 miners
3 feet space
Ground
shelf width will be kept short enough to face the exhaust fans
since I have this set-up for exaust
------- vent--------vent----------vent---------
Vent---Fan--vent---fan---vent---fan--vent---
each vent is 2.2f and so are the fans but distance from first to last fan = 2.2*5 = 11 feet so out of 40 feet in total I will only utilize 11 feet , so here is how it look
------- vent--------vent----------vent---------
Vent---Fan--vent---fan---vent---fan--vent---
------- 2*s9-2*s9-2*s9-2*s9-2*s9-----------
