Correcting overcolonization of casing
    #5632714 - 05/15/06 01:51 PM (17 years, 8 months ago)

My friends casings have overcolonized ALOT. 50-100% of his casings are covered with mycelium. Is there any way to prevent overlay?

Could he soak and refridgerate overnight?
OR
Could he path the entire casing?

well what is it. 50-100 % is a big difference. you could have 100% colonization though and still be fine if its thin. this would be ok if it got to 100% after days in the FC. if its already at 100% before you even start fruiting it then that could lead to overlay so you would pwatch it and toss it into the FC.

Some of the casings are 50% covered and some are almost 100% covered with visible myc. After casing they were left in the incubator for 5.5 days due to a busy schedule, not thinking they would colonize so much. Most are just whispy strands of myc, it isn't packed tight yet.

They haven't been fruited yet. The casing containers are already filled but he could put a real thin layer on top, not sure if that would help enough though. He was also thinking about soaking the casings over night in the fridge since the casing mix was a little dry to begin with anyway. He was thinking the direct water contact may reduce the myc growth on top of the soil long enough to get pins. Dunno though.

It does no good to ask for help for a 'casing'. You need to say what is 'cased' and also what material was used for the casing layer. If you used coir, then you added a second layer of substrate, and still don't have a casing layer. If you used peat, you want to introduce to fruiting conditions when the casing layer is about 50% colonized.

Here's a rule of thumb. If you suspect overlay, YOU DO NOT HAVE IT! Overlay is perhaps the rarest of all maladies that affect us as growers. Read hyphae's stuck thread at the top of this page.

I know there isn't any overlay yet. He is worried about getting overlay after the first flush. It is WBS cased with verm/coir, 1/4" on bottom, 1/2" on top. Mixture was unmeasured, 1 brick coir to half bag verm, so what? 60% coir? My friend has never had myc cover the top of the casing layer this much before so he doesn't know how much of a problem it will be. The first flush shouldn't be a problem, but 2nd and 3rd is what he is worried about.

60% coir is the same as no casing layer at all. It will fully colonize. It's ok though as cubes will fruit without a casing layer, but not quite as well. I would recommend 50/50 peat/verm for your next project. Peat is also a fraction of the cost of coir, so you'll get a better product at a reduced price. When/if you switch to peat, be sure to only case the top. We don't case the bottom of a bulk substrate.

Yeah, in the past he has never used as much coir and think he may have did coir/peat/verm once. As for being a fraction of the cost, coir is $5 a brick, peat is about $3 a bag. Not really a big deal either way.

Thanks for the advice. Anything need to be done differently after the first flush? Think scratching would hurt it was too much but what about adding a pure verm layer on top? Worth it?

Personally, I'd leave it alone and just let it fruit. The peat I get is about ten times the size of a fully expanded block of coir, for six bucks. Also, peat is far more suitable for a casing layer. Mixing in a bit of coir with the peat has proved to work well for a lot of folks.

Cold shocking is a tool that can be used with coir casings to control their colonization also casing and putting them directly into the FC also works but will require some trial and error.
