fae issue or what??
    #18939934 - 10/06/13 12:00 PM (10 years, 4 months ago)

I think this is a fae exchange issue, but I don't know how it could be. My tray has some caps covered in white. Some just have spots. I have upped the fanning to 5-6 times a day and have a hepa on low circulating the air several feet from the chamber. This tube was a mono set up I got from a buddy who never fanned, and had huge fruit.(which would need way more fae than my little fruit) The tub has 1/4" holes spaced 2" apart a few inches above the fruit. six 1 1/2" holes 3" above the small holes with poly.Perlite in the bottom. The extra air isnt helping the white stuff on the caps, but is drying out sub, which I heavy misted a few times. RH is always above 90. Light cycle 12/12. It is a grow light, but the tube is also getting indirect window light, which is the right spectrum, even if the grow light is not.  Attached are pic of chamber set up and problem shrooms. I can see a little bruising on the shrooms on the cake today which makes me think I'm fanning too much...  thanks for the advise. It's driving me nuts that I can't remedy this! Also why are shrooms growing out of the bottom of 1 cake but, nowhere else?

I wanted to say something but I don't even know where to start lol.

The conclusion of what I would say, along with others most likely, would be: You've got your setup all wrong dude

That tub needs to have 4-5 inches of wet perlite.

It needs 1/4" holes every 2" in a grid pattern on all 6 sides.

It needs to be elevated at least a few inches off the table so air can circulate through the perlite thus giving FAE and high humidity through evaporation.

so why when my buddy was growing bulk, no perlite, just dumped 6 jars into sub directly into black bag in bottom of tub..cut the bag to sub level after colonization, and did nothing but mist once in a while. why was there no fae prob? is it because of the 1/2 sgfc aspect (perlite and tray & cakes on top of it) versus a just colonized sub in the chamber? Are holes in the bottom a must for the circulation? How do I keep the mess from coming out of the holes on the bottom if that is what I need to do?
Thanks

A bulk substrate provides its own humidity. What you have there needs assistance from the perlite to create enough humidity. The perlite needs to draw air through the bottom of the container in order to do this

In a nutshell, monotubs and sgfc work differently. The SGFC is generally used for cakes. The cakes are not enough to get air circulation going on their own. A mono has bulk and will produce enough heat and moisture to help aid in air circulation.

1/4" holes every 2" in a grid pattern on all 6 sides allows fresh air to flow in, stale air to flow out. This is called FAE, fresh air exchange. The holes in the bottom allows air to flow from underneath and through the perlite. This aids in evoporation of the perlite which is where you get your humidity from.

Only a little bit will fall out at first. It's the "Three Stooges Effect". Ever see the Three Stooges get stuck in a door because they try to go through at the same time?

Your buddy used the container as a monotub (fruiting substrate directly in the bottom).  A monotub uses the substrate itself to support the rH in the tub.

You should have at least four inches of well drained perlite in there to do any good. And since it works from surface area exposure, when you set your trays on it, it covers up most of the surface so the perlite is basically ineffective in there.

The reason you are getting pins on the base of your cakes and no where else is that that area is the only place with a suitable micro-climate for primordia formation.

At the least, the holes in the container should be closer to the top level of your perlite layer (which should be 4 inches).
