Gas Exchange problem?
    #11211652 -

I'm running a mono tub I spawned with coir/verm/castings/gypsum last thursday (a week ago. Humidity seems to be fine (light condensation on walls, some water droplets on mycelium. Hygrometer broke :frown: ). After about 3 days worth of growth, it seems to have stalled.

My bulk was prepared with 1 brick coir, 1 qt verm, 1 qt castings, 1 cup gypsum, pasteurized in a bucket with 4.5 qt water.

My mono has plenty of holes (18 1") but they're all around the top. Am I getting a stall from not having proper GE at the spawn level?

You should have holes in the bottom as well.  Mine was a mini tub, but you get the idea.



See the polyfil on the bottom.

-Some strains are noteably slow what strain are you working with?
-3 days isn't that long. Some people have reported over 2 weeks until they were able to case.
-Yes GE (but I think you mean FAE at this point of the grow) could be a problem. It is typically recommended for a grower to have holes down by the substrate, but slightly above it. SO go for putting some holes near the bottom.
Is there any side pinning?
I know CO2 is what's needed for the fresh air pinning effect. It's heavier than O2. So (i'm trying to figure out the best hole situation as well) it seems as though more holes in the top with some on the bottom would be best for a top to bottom cycle of CO2.

I'm trying Guadalajara. It has been 7 days.

I'm only about 50% colonized on the bulk.

I thought only GE was needed prior to fruiting.

No pinning at all. Still more food to be eaten.

As of now, on each side I have a row of 5, then a row of 4 1" holes. I just added 4 holes (2/side) just over the top of the bulk. I'll see how it goes.

you have to close up the tub (GE only) untill its fully colonized then open the tub up and polyfill the holes for FAE and give it light to trigger pinning.:thumbup:

if it stalled then its just probably switching phases from eating/consuming nutriants to forming hyphal knots.  if everything else is good. but not if its not fully colonized!

just my guess/opinion with out pics.:shrug:

ok in the incubation stage :thumbup: got ya
yeah, i would recommend holes down near the sub. and yes, no FAE yet
Is there any dryness? smells? color change?
There was a tub almost colonized except by the polyfil on substrate level. Polyfil replaced with tyvek and it finished up in the next days.
Good luck

How do you promote GE w/o some sort of vent? Only thing I can think of with a sealed off tub are some notes by RR about problems growing in 1/2 jars, as most people don't put them on a 45 deg angle, therefore not giving proper GE. The way it was stated in RR's notes, it made it sound like vertical distance was a possible problem with GE. If the only place for GE is at the top of a tub, isn't that bad?

I put 4 1" holes just above the sub's level, stuffed with some poly fill.

Dryness: myc seems to be collecting condensation. Coir appears to be at field capacity via ocular inspection. 30 hours + after hole drilliage, there appears to be a transformation from the brown to a white cottony substance. No discernible odor, at least not through the poly.
