SGFC question about hole size and frequency

quick question. i know that the rule of thumb is to make a ton of small holes like 2 inches apart on all 6 sides.
but i've also seen larger holes filled with poly fill.
if one were going to be using BRF cakes can you go with the larger holes and poly fill or is there some reason i only see this with mono tubs?

Theres not enough substrate to use a mono with just a half dozen cakes or something.
It works well if you absolutely pack it with cakes.
Just roll with a SGFC if you're making cakes. Its the standard for a reason. 
Also perlite is easy because there is no "dialing-in" required with SGFCs. There is with monotubs.

i guess i'm not explaining what i'm picturing in my head very well. lets say i take a tub that has several inches of perlite in it.
i have brf cakes on top of that
could i in theory just do larger holes with poly fill rather than tons of small holes?

Well, the perlite wont be nearly as effective if it doesnt get the airflow that a standard SGFC provides. Those small holes are a pita to do but it is pretty necessary.

NO you can't
How the hell are you going to put several inches of perlite in a SGFC with 2 inch holes in the bottom? Think about it...

Monotubs and Shotgun Fruiting Chambers (SGFC) are two entirely different things, used for entirely different types of grows. If you are doing cakes, make a SGFC.
A monotub is for doing the monotub growing method, which does not involve cakes.

Nah think he just meant to dump perlite in a standard monotub and put cakes in it.
But yeah, no bueno.

indeed. i wasn't picturing having 2 inch holes on the bottom or anything like that.
so out of curiosity, why does the monotub work for large platters and not lots of smaller cakes?

as said monos can be done.. monos keep humidity up by using the substrates evaporation. You need enough substrate mass in there to keep humidity up. This is like in the ballpark of 20ish cakes.

To answer your question more directly OP - the 1/4" holes on the bottom of the SGFC are there so that air can travel up from the bottom of the chamber through the holes>through the perlite dragging water with it. The large holes will not work with perlite because the perlite only does its job when there are holes in the bottom of the tub. The airflow drags water with it, sustaining humidity.
When we fan after misting-we are getting rid of that humidty-allowing the moisture on the cakes to evaporate again, stimulating pinning and repeating the cycle.
Hope that helps.
IE... Make a SGFC to spec = Get the goodies.

yes that helps thank you.
with that being said. would the small holes on the bottom and top be ok with big holes w/ poly fill on the side?
The reason i ask is i have a tub that has larger holes on the side already and just want to know if i should buy a new tub or if that one can be used.

You can just throw some tape over them. But tubs are cheap, so its your call really.
