the first flush of the dpoo is almost done and a dunk is going to be done soon. my question is, the top surface isn't at all flat and smooth as it should have been or 100% colonized. there are many tiny pins, some aborts(black caps) others that just won't mature in time if at all. because of the uneven surface many of these pins are in little valley and bumps of the surface. when it comes time to dunk what do you do with this? remove the uncolonized bits? use tweezers to get rid of as many of the aborts/pins as possible. some will be very mushy and probably just break off where they are grabbed and maybe leave behind material that will rot. would it be best after the dunk to flip the sub so that the bottom which is flat is now the top? if so, i know that will delay things, but would it be treated any different from there than if wasn't done? and if so should it go back in the tray so that the bottom(used to be top) doesn't start to fruit? thanks :)

From the looks at the pics you got some time before final harvest. As far as getting all the aborts and shroom that will never mature, get them all off as best as you can. From my experance left over fruit bodys will rot and cause contam.
Now fliping the sub. I did a flip on my pe grow that is currently going. When I did the flip it pinned on the orignal top, the new bottom. If that makes sence. Since the new top wasn't pinning, I fliped it back over and let it fruit from there. The orignal bottom never got fruits and the crushed fruits that were fliped back right side up came to and they are getting very large. So all n all don't flip the sub. Just imo and experance.


Ps don't dunk the poo sub to long. Id say 4 to no more than 8 hrs. I've had bad results with a dunk longer than that.

IMO, the uneven bumpy surface is a good thing. I would not flip it. The bottom will take extra time to start pinning - the top already has the beginnings of your post-dunk flush in it.

I would let that sub go for a while before dunking it. I think it is going to put out a nice flush if it gets a chance.

Before dunking, it is a good idea to get all the mushroom tissue off the sub. But you don't have to go crazy (as you start picking really small pins, you will just see smaller ones everywhere).

Some of those ultra tiny guys can survive the dunk and pop up 1-2 days later followed by another strong flush.

well the dunk is done and lessons were learned for the next poo run. the poo was not broken up enough at all, especially the top layer and nothing being 100% colonized didn't help either. anyway, it's been dunked and as much of the uncolonized poo as possible without going nuts has been removed. was more than i thought underneath. some black, a lot brown, but not 100% white like it should have been. i can't say that it's looking the way i think it should. but i don't know if it's bad or how bad. what do you guys think? the bottom layer is pretty solid white and like it should be, the remain brown weakly colonized top layer isn't very thick at all.

Give that sub a few days and it will fruit again.

here it is 6 days later. looks like some new myc started growing over the remaining uncolonized dpoo that didn't come off during the dunk. maybe after the dunk it should have been incubated a little? anyway, a couple pins are showing but nothing special by any means. also since the dunk it has a bit of a manure smell to it. obviously from the uncolonized part being wetter than it was when it was spawned to. is this going to be any kind of problem as far as the grow? and suggestions or predictions for this? thanks

I've never incubated after a dunk. If you smell manure keep an eye out for contams.
On your next grow rember that patents is a vertue. let the sub fully colonize than case. Let the poo turn almost fully white than case verm coir 50/50.
I've incubated after casing and also cased and left in the fc. I found that caseing and leaving in the fc has produced huge flushes, but takes a very long time.

Several things.

From your first pics I did not see any aborts. They were all starting to be fully formed fruitbodies, all-be-it small. This was likely because your substrate was not fully colonized...and a number of other factors that I cant diagnose without more information about the grow.

The surface being completely flat with a bulk substrate is not a major problem. Other factors would have caused the small fruits.

It is best to get as many of the aborts before a dunk as possible, but it is not necessary to get every single one.

Flipping the substrate is, at least IMHO, a very bad proposition. Reading though some recent posts, I have seen several people talking about it. I would NEVER recommend it. EVER.

Mushhut has it right when dunking poo. It works best with very short dunks. A matter of hours.

No need to incubate after a dunk.

Also, please use a better method than hydroton hydration for bulk subs. If you are going to use that type of chamber, use cakes. Your results will be much better.

thanks, lots of good info there. what specifically is the issue(s) with a PMP (4 inches hydroton with 3 inches of water and 2 long bubble wands and a large aquarium pump) when used with bulk?

With that type of setup, multiple cakes will give you more of a surface area to grow with...thus more yeild.

Also id just use several inches of perlite instead of the water, pumps, and hydroton.

KISS

You will get the same results. And it would be easier to multiply what you are doing with more of the same setup.

ok, so it's not so much that bulk is bad in there, just that cakes are better?

as far as the perlite "shotgun" type...i have one of those going also and it's worked fairly well, but i HATE dealing with perlite in between grows. it is such a mess and pain in the ass to deal with. also i'm away for work 14 hours or more at time and spend a few nights over the g/fs so that with trying to get 6 hours of sleep doesn't leave much time for fanning and checking up on RH,which is usually fine in a shotgun, but not always when you have an AC running in the room. also the pmp can be tucked away and well hidden when the need arises and left untouched without hurting FAE.

and i have no need to multiply the setup at the moment. that big PMP holds a LOT of cakes and there's always the option of stacking

i'm not shooting down shotguns, there is no question that they work and work great. but this is an experiment in trying to make things as automated as possible while i'm away. thanks for all the info nonetheless :)

Why do they call it "shotgun" type now?

that's the name i've always hear and used when talking about a tub with a ton of small holes and damp perlite used for cakes. guess i picked it up over at the other place ;)
