Is it worth it to install a aquarium air pump with an air stone in a SGFC?
    #12828623 - 06/30/10 02:49 PM (2 years, 11 months ago)

Hey folks,

I just finished my test jars for my grain LC. I plan on using the LC later to inoculate 16 quarts of rye.  Anyway, since I am using PF as my test jars, I am feeling an overwhelming sensation of nostalgia to return to the tek that got me started in this wonderful hobby.

I was planning on building a shotgun terranium, which will likely be about 14 x 24 x 12" or so.  I am just going to use 6 cakes with a perlite depth of about 4-5 inches or so.  Would it be worth while to install a cup of water and H2O2 with an aquarium pump and air stone that will run for 15 minutes maybe 8 times a day or so?  Would that provide any FAE while maintaining a high RH? 

I was thinking about this model with this airstone. 

Pump

Airstone

What say you?

I did some automated stuff last year that work well.  I made a SGFC type that was connected to a computer fan and a cool mist.  Worked quite well, but I would rather do something simpler like the aquarium pump and air stone.

First, don't make your LC's with colonized grain, use agar and it will have less chance of contam, but whatever works for ya.

Second, no- you don't need that with all the perlite.

Here's to nostalgia:cheers:

Grain LCs are actually known for their superiority over sugar based LCs because of their resistance to contamination.

And I am more curious about whether it will actually provide FAE without a loss in RH.

The point of the SGFC is that you don't need the airpump. Air is pulled in through the holes in the bottom where the perlite is because of differences in pressure and the air is forced up through the perlite providing FAE and upping the humidity.

And yes, grain LC is superior

I find a window in the kitchen and I let myself in. Rummage through the refrigerator, find myself a beer. I can't believe I'm really here and she's lying in that bed. I can almost feel her touch and her anxious breath. I stumble in the hallway, outside her bedroom door. I hear her call out to me. I hear the fear in her voice. She pulls the covers tighter, I press against the door. I will be with her tonight.

I totally understand that.  But it would be cool if I could just leave the SGFC alone without manually misting and fanning.

I've tried air stones and never found any benefit with SGFC. 

Maybe I'll have to try grain again, it never worked as well for me.

Yeah, I might just KISS (Keep it Simple Stupid), but I would think attaching a cool mist via clear hose to the center bottom of the SGFC would work.  All you would need would be a relatively thin screen to keep the perlite from falling into the hose and clogging it.  I would probably bury it about an inch or so within the perlite. 

Maybe I am just being ridiculous, but it sure is fun to brainstorm.  I think I may try that.  I don't see why it wouldn't work if you put it on every 6 hours or so for about 5 minutes.

I've heard that an aquarium pump doesn't move enough air to be beneficial in the average SGFC.

It's all about the size of the air pump.But there is no need for one in a shotgun FC...now if you were using a PMp this would be a different story.

If you are going to use a air pump then build a PMP, I find they outperform shotgun terrariums. Don't bother with air stones use bubbler bars. Make sure the pump can push alot of air don't cheap out and get a small pump. Their is no need for h2o2 as it would revert back into h2o in no time in a climate that is aerating it, and exposed to light.

6 cakes is worth it, as it can yeild you 2-3 oz

You don't necessarily need to fan, but you do need to mist.  Your cakes are supposed to begin drying out, and then you mist to replace that moisture.  This ebb and flow of substrate moisture content is a major pinning trigger, something that wasn't fully understood in the early days.  Misting should be done by hand so you can use your eyeballs to know when and how much to mist.

So if that is true, then would using the wax paper trick maybe for 12 hours and then not for 12 hours make a bulk grow pin better?  Is that the trick?

The trick and biggest pinning trigger is not get water to evaporate off the sub, but to also replenish it

this, a pump will not help a sgfc at all, a diff set-up is used in a pmp, so either a new set-up or stick with the sg

all i read is the title

no, you dont need anything other than the SGFC to fruit whatever it is you want to fruit

adding shit probly wont make a difference, as the SGFC is designed to just sit there with some misting and fanning

I might go ahead and make a PMP instead of a SG.  Maybe.  I can't decide.  I have 6 cakes and tray I want to try out and I would like something that is pretty much care free and automated, but I feel that even with the PMP I will have to mist and fan as needed...

That terrarium you just posted would be a bad idea. the mushrooms in the picture look like they lack FAE, and since you are using a small pump that pumps air into bottles of water in the terrarium I can see why it lacks FAE.

A classic PMP will work 10x better then the one you just posted.


This is a proper PMP



I find a PMP beats out my Shotgun




3-4 inches of perlite, 1 inch or so of water and a big pump with duel outputs pushing lots of air into 3 bubbler bars under the perlite.

Also with 1/4 inch holes in the lid

What if you made a PMP with about 3" of hydroton and 1" of perlite on top of hyrdoton.  You could then fill it with a little less than 3" of water in which the air stones will run. 

Do you guys manually mist and fan with your PMPs?

Look at the size of the chamber you have and look at the tiny pump you have.

Having bubbler bars under the perlite and some water will do wayyyyyy more then having it in bottles.

You can even tell by your mushrooms in the chamber that they lack FAE

Also the pump you have is not rating for 2.5 CFM

use bubbler bars not air stones, also yes still mist and fan

it depends on the outside weather. My triple bubbler raises air about 20% over ambient rh, so if the rh is less than 70% I do. I wave the lid over it a couple of times a day to keep stagnant air moving

My pmp works different from yours. air comes out the holes at the bottom. All air passes by the cakes on it's way out. Way more efficient than trying to blow air up from the bottom. Co2 is automatically evacuated in my system Seems like I have plenty of fae WHat do you see to lead you to the conclusion I lack FAE?

I am telling you that small pump you have will not do much for that size chamber, First off its a very small pump and you have it in a large chamber.

Air coming in and though the bottles will not pass over the entire chamber and over the myc like you think it will.

Look at your pictures the mushrooms have very long thin stems, a trait that have noticed in the other pictures you have

The bottom line for the original question is don't use an air pump in a shotgun terrarium.  It will create a slight positive pressure inside the terrarium, messing up the natural flow which makes them work.

I think I will just go with the SG.  I have more perlite than I know what to do with and it is very simple. 

Thanks again RR.

I have the same plan with a SGFC and a pump. I understand, its a bad idea, but i still have to solve a problem. I will be away from home for 5 days. I have BRF cakes, dunked and rolled. Possibily, the pinning can begin any time. My plan is, to put an airstone ended hose through the lid of a small plastic container, which is filled with perlite and water, and another hose out of it, and bury this hose under the perlite in the FC. Its end is closed, and i made holes on it. The pump would be controlled with a timer. This should make enough FAE, and because of the small water/perlite container, the perlite in the FC wont get dry. I allready made the setup, but now , that i read this threadm i have bad feelings about it... It would be only 5 days...

you'd prob. be alright if you left the pump on. Having that triple bubbler on mine reduces the airflow, so you don't dry the terrarium, and makes nice humid air. Thats the benefits of the triple bubbler

I ran a cool mist into a SGFC with one cake when I was gone one weekend (about 3 days) last summer as a test run.  I came back to find 40 wet grams of Golden Teacher. 



They dropped their spores, but oh well... :mushroom2:
