Dunking monotub
    #26638986 - 04/30/20 01:13 PM (3 years, 8 months ago)

I've got a tub and the sub is shrinking rapidly. I have a layer of perlite in the bottom but the sub is still dry. How would I go about dunking a tub with perlite?

You have a bulk substrate sitting on perlite in a monotub?

First off why do you have perlite in the bottom of a monotub??

Is it fully colonized? Is this a tub with holes + polyfill?
Have you already had your first flush or no?

I need to know a little more about how you made this tub to tell you what's wrong and what to do

I’ve seen this before. Some grow kits have that setup and people run with it.

I have perlite in the bottom to help with humidity since keeping rh up for me is extremely difficult. The sub is sitting on aluminum foil. There are holes drilled and filled with poly and I have had a 1st flush

So it’s like a block of colonized bulk sub sitting in a tub with perlite? Colonized in a tub smaller than what it’s currently in? I’m just trying to picture what’s going on with no pics  :picdidnthappen:

If that’s the case you can just pick it up and put it in a tub of water, weighed down.

Tub looks like this, 66qt with 6qts of perlite under the foil.

No idea why you are using foil or perlite at all or your hole configuration.

In a traditional monotub with holes and polyfill, the holes are closer to 2" and there is 4 on the bottom, two on top. You stuff the bottom holes very tightly, and the top very loose. Then you dial it in, if your substrate is too wet on the surface (pooling condensation), you loosen the poly to increase FAE, if it's too dry, you tighten it. A healthy layer of tiny droplets across the surface that starts to dry up immediately in front of the bottom poly is dialed in- you are giving max FAE you can without crying it out.



Anyways, I guess I would give your substrate a heavy misting if it's dry. Has it had it's first flush yet?

Bottom water a dry sub as misting won't help much. The myc at the bottom of the sub will supply the water to where it's needed above.

(Whoever posted above me deleted I was replying to someone that said if sub is dry mist it )

He has perlite on the bottom, then his sub in a liner of foil. I suppose if he can pour water into the foil he might be able to bottom water.

Yea. I'm aware. I'm just speaking generally. Obviously his circumstance is unique.

What an...interesting approach...
I'd pull the sub out, dump the perlite, put the sub back in and dump it like normal...Or I guess you could just fill the tote with water, when the sub floats, pour off the water+perlite, then do the actual dunk by pouring water in the aluminum liner, draining like normal.
I'm assuming that sub has had at least 1 flush and an attempted dunk already? Looks like it's been through some shit in it's life already!

I'm confused to if that is the ubstrate in  in his photo or did he mean it's a photo of one of his other subs?

He hasn't told us if it's had it's first flush yet.
Substrates are supposed to shrink as the mycelium consumes, it doesn't necessarily  mean it's dry

He did say it’s had it’s first flush, though I don’t know if the current mushrooms growing are the first flush themselves or second.

To the op, that perlite isn’t really helping anything since it’s trapped underneath the bulk sub. It might be providing a very small extra bit but the way it works it by having an extremely large surface area to evaporate from because of all the nooks and crannies but without exposure to the air it can’t do much.

I would just mist the surface in this case. The sub is already cracked and I can see a major mess in trying to get that up and out. Unless you can life it by the foil maybe with another set of hands and then dunk it elsewhere or dump the perlite and dunk in its tub

Ah, I missed this

"There are holes drilled and filled with poly and I have had a 1st flush"

That changes things- subs shrink as they consumes, they can shrink quite a bit from the walls especially if the first flush was a big one.

Just give it a heavy misting

Next time change your approach. Go with a traditional 6 hole monotub so you can dial in your FAE, or do unmodified. I suggest un modified.

No more foil and perlite
