i was under the impression that the deeper the substrate, the bigger the mushrooms. maybe im confused

i have a few questions on bulk tubs grows. i was inspired by so many beautifull pictures by members that i had to try tubbing.
my question is, how do you gauge the proper moisture level.
i have several air exchange holes cut out around tubs, using coffee filters 4ply for filter. also manually exchange air 6 yo 10 times a day, basically whenever i walk by i fan the tubs.
the tubs are lightly misted once sometimes twice a day, just enough to keep the casing layer(straight verm) moist.
here is a pic one of the tubs, these are ten gallon, wanted to start small before i tried something like the 31 gallong jobs i have seen.

An experienced grower can just eye it. If the sides start to shrink then it's too dry. As long as thier is moisure on the inside walls then it should be ok. Eventually it will start to dry as the mushrooms suck up the moisture. At that time you can use the Flood Tek to gently flood the surface.

substrate 2and 1/2 inches and the casing layer is less than a quarter inch. wanted it fairly thin so the substrate could breath.
Max thats pretty much how i have been keeping an eye on moisture. didnt know if there was a trick i was missing.
thanks

pure verm casings are a bit tricky as the color doesn't change much
unlike peat or coir.
but verm holds a lot of water
and most people seem prone to
over-saturating their casings
so tend to err on the dry side when in doubt.
of course a casing that thin
will dry much faster,
with 2.5 inches of sub
i'd use more like .5-.75 inch casing thickness,
instead of <.25"

I'd prolly avoid fanning that much. It looks like you've got plenty of ventilation for that tub. 2 times a day will be surfice.

extra ventilation never hurts, assuming it's properly humidified,
and can save the day.
esp. in sealed bins,
not much air exchange going on thru filters
and casings really need air a few times an hour
so i'd say more air = better in this case.

what is the flood tek?

when making air exchange holes, is polyfil or tyvek really needed? or is it there to help slow the air circulation.

i now have 3 tubs going all with different amount of air vents cut into them. the one in the pic above has the most(8), the next one has half as many holes, and the third has none.
question for hippie, should i go ahead and add more casing to my tubs or should i leave it alone? the first two tubs are close to full colonization.

i have been slackin it lately with everything in general. the top is now almost comletely white and there are lots of pins forming. it looks like someone poured white sprinkles all over my casing. i hope i get a good flush from this one.

well, there is an abundance of pins on the casing. i hope i like these mex-pals. i will put some pictures up when there is something worth viewing.

there is some correlation, true
but most are more concerned
with total yield
than they are about individual shroom size.
a given quantity of substrate divided into
several shallow trays
often gives more weight in any given flush
than one big deep tray would.

IMO I have seen what Hip has posted above...I did get more fruits/yield from many shallow trays apposed to 1 deep tray.

Hippie, what depth would you consider to be the deepest shallow, and the shallowest deep, respectively?

Let's just assume that the hypothetical substrate is horse poo.

Yes, let us know, I am interested as well. What would be the shallowest deep, respectively?

If you really care about 'yield' you will care about shroom size eventually.

Cleaning them is a bitch so you really do not want a million that weigh .1g dry.

Something closer to 1-2g dry is probably less effort to harvest, dry, clean and handle.

3-4" deep sub + .5-1" casing layer is optimal for Billys setup. Bily likes to hook up his friends though and worries about harvest effort, drying effort and cleaning effort.

Hydration will matter a TON to size also.

ok, i finally stopped being a lazy bastard and itook some pics for the update. as you can see, it is very slow, but it is really pinning now. i think i have a couple albinos in the group also. i am going to clone the 3 white bitches(just like on the chappelle show) and start some albino casings.
