Which depth is better?

[Aoutiv]

Edit, added .5 to 2nd choice to even out numbers.

So i've been trying to find out which depth is better and have been getting mixed responses.

1.5 inch depth, 9 inch, by 10 inch.

OR

3 inch depth, 8 inch, by 5.5 inch?


Both have the same volume but much different surface area. One has 90 square inches, and one has 40 square inches.
It seems that 1.5, how it is shallow, would be a strong enough cake to hold some big boomers, and of course would have a better yield at first. It would colonize faster than the 3 inch depth, but it would not have as many flushes as the 3 inch depth would put out. So, technically, in theory they SHOULD harvest the same amount. So which one is better then. Some have said that cubes with sub that is less than 2.5 don't fruit as well, but does anyone know why this is? I don't know, interested in feed back.

So, someone just said that the lower depths do not produce mush as well as deeper and said it was somewhat of a mystery. Any info on this?

The only advice I can really give on the matter is this. Deeper the sub the better the flushes in swims experience.

Also outdoor's need nice and thick sub(4-5inches). Bugs get hungry and worms get lost is the reason why that is recommended.

The science of it I am not certain.

The shallower depths may release moisture from the substrate too quickly, especially for repeat flushes. I'm not positive, just a guess. 3" seems to be a good depth in trays, with 1/4"-1/2" of casing on top.
