Fruiting chambers - monotub vs shotgun
    #18911320 - 09/30/13 01:27 PM (10 years, 4 months ago)

Hey y'all...

Newbie here, and I am in the midst of my first attempt to grow.

Here' a pic of my inoculation chamber (for shitz and giggles).



My jars (PF tek) are currently in a dubtub incubator (day 3).

Anyway, to get to the point, I keep seeing monotubs with some excellent yields. I was wondering the best fruiting chamber for a newbie like me. I want to build the chamber while my cakes are incubating. I have a fogger/mister, timers, 2-tube aquarium air pump, a big tub (clear) and a few other things. Of course, I bought these before I saw this monotub stuff. I was thinking of just staying the course with this build, and attempting bulk grows, if I can successful get this batch to bloom, in smaller pans just placed in a shotgun chamber.

Thoughts?

Most of those fancy things you have (foggers, timers, air pump etc.) are pointless. Just use an good ole fashioned SGFC. It's as good as it can get and very simple. BRF cakes don't do well when spawning to bulk, so just birth those and fruit as they are. If you want to do bulk, you'll need to learn to use grains as spawn. Good luck!

If you haven't already done so, some of the best info around for handling cakes and more: RogerRabbit's Let's Grow Mushrooms

Watch the preview videos for BRF tek and Fruiting Chambers. I paid the $9 to download them all. Lot's of good information.

Yeah man, a small pan or tray placed in a sgfc will definitely work.

Btw SGFC>Monotub because it is better at providing fresh air exchange and keeping relative humidity high. It's just that a monotub is far more convenient. That and you can't fit that much in a sgfc compared to a monotub before air flow begins to become restricted in the sgfc and the perlite in the sgfc starts getting compressed from the weight of all the substrates within it.

If I have to do container growing I prefer a traditional FC.  This is just like a mono cept you use four inches of well drained perlite in the bottom instead of substrate.

That's interesting Gretchen. I was under the impression that there needs to be holes in the bottom of the tub for the perlite to function properly. How exactly does this traditional fc work? I think I've seen people grow P.Mexicana in plastic containers using this style of fc.

Love.

I'm interested in hearing about that as well. How does that work?

I am going to proceed with the build of the SG chamber. Do you use polyfill for the FAE holes, or just leave them open? I am afraid too much of the humidity would seep out.

Also, I was thinking of using hydroton for the base with an air stone beneath. The reason is, my basement is FREEEEEZING, so I need a heat source. I figured the hydroton would allow me to put a small aquarium heater in the tank.

Thoughts?

BTW... I appreciate all of your help. I'm so stoked about this stuff.

Those are the videos that got me excited about doing all of this. I just started getting torn and greedy about getting a great first-time flush. :crazy2:

Thanks!

No, because it doesn't work that way. Air enters the bottom and absorbs moisture as it travels up and out the top, taking stale air with it. build it exactly per the Shotgun Terrarium tek and have it elevated on blocks so air can enter the bottom.

Perlite works by surface area exposure.

Perlite is made of small pieces of porous volcanic rock. If you look at it closely (microscopically) you'll see that it looks like swiss cheese with (relatively) huge holes. When water is added, it is wicked into these pores of the perlite. This porous structure then serves to slowly evaporate the water back into the air. The huge surface area in the micropores of the perlite helps the water evaporate forming a vapor of tiny droplets which tend to stay well in the air.

The traditional FC uses four inches of WELL DRAINED perlite in the bottom. If it is saturated or in standing water it cannot function properly because you "lose" the surface area exposed to the air.

The traditional FC contains several large filter covered holes (micropore or polyfil, sometimes tyvek) just above the perlite layer to allow fresh air and gas to pass through, and also helps to keep particulates out.  A couple holes are installed in the upper corners to increase "air flow" in the fc.  It is still recommended that you fan and mist about three  times a day.

If you were to lay out the holes for a traditional FC it would look something like this:

            :: . . . . :: . . . .

The size and number of holes depends on the size of tub you use, but basically you want to use 1-2" holes. And they should be set about 5-6" apart.  Remember you are applying a filter which will reduce the effectiveness of the holes, so the holes are a bit bigger than you might expect.  But the filter material helps to keep rH in, while letting air through, and also helps to keep particulates and insects out.

I like to heat up a small spare piece of pipe, and melt right through the plastic to make the holes. Of course this is nasty smelling, and I do it outside or in my garage.

Most people have good success with RR's SGFC.  I do have some friends in drier climates that just cannot get them to produce the desired results however. 

The number one fail I see with perlite is over wetting it, which is basically impossible with a SGFC , because its like a big spaghetti strainer, and any excess water will just drain out the bottom.

A side note: even if you decide to use an air stone or bubble wand, you will need to fan the fc out to completely evacuate the FC of CO2,  a pump will help, but ultimately just dilutes the CO2. 


May the force be with you :crazy2:
