 your opinion on spawn ratio.

What are some of the negatives, if any, of spawning a large amount of WBS to coir and coffee? I just spawned my WBS to coir plus coffee at a rate of 1:1 yesterday as some of my 1:4 parts coir have been contaminating with mold, probably due to slow growth in the spawn run of 14 days sometimes.
Will I suffer in yield by having so much spawn to coir due to less ability to hold water? I spawn 28 quart jars to a brick of expanded coco coir, 1.5 quarts each of coffee grounds and verm, and two cups gypsum, and a cup of lime. Does this sound good? I think the PH is around 8. What is the ideal Ph for some of ya'll?

I'm not sure about yields or moisture or any of that - but that's an INSANE ratio! AFAIK a brick of coir makes 8-10 qts of material, so your final bulk substrate is ~14 qts. And you spawned 28 qts to 14 qts. The highest ratio I've heard of anyone using is a straight 50/50 - but you used twice as much spawn as bulk, no? It should definitely colonize quickly, but that's all I know.

haha most people go with a 1:5 or a 1:4 ratio (spawn:bulk) you kinda used spawn as your bulk!  edit: i would use a casing layer to aid in moisture on this over spawned grow! no harm done.

It will not harm your bulk grow at all but you may want to consider applying a casing layer as suggested, 28qts of WBS to a brick of coir? It should be fully colonized within three days of recovery.
The other problem I see is that you used excessive amounts of coffee grounds, coffee grounds will create a p.h swing unfavorable to mycelium, the mycelium will colonize it but it will take some time to adjust the P.H of the substrate, this can result in poor fruiting and/or longer fruiting times.
28qts sounds like the entire surface would be coated in wbs spawn...apply a verm/coir casing or a half cm coir or verm layer. Either or.
Forgot your questions...I really need to answer then rant..
TMC has the optimum P.H level for cubensis listed as 6.2-6.4
I see that you added gypsum and lime but I doubt it would be enough to adjust the P.H to a optimum level with that amount of grounds... A P.H of 9 is going to cause the mycelium to slow down Like i was saying since it needs to adjust the P.H level of the bulk, trich is a acidic spore and thrives in acidic conditions, could explain why you are experiencing problems with it. Get your P.H down to 6.2

i would leave out the coir and use only verm or the 50\50+ tek. coir is a better bulk substrate than a casing layer. casing with coir is outdated because it has been proven really nutricious to mushrooms.

We need a buffering compound that keeps the substrate at the right pH...

Your contams aren't coming from a 1:4 ratio of spawn. Like was said above, you may be using too much coffee. You could also have too mcuh water in your coir. I like to leave my bulk subs on the drier side for faster colonization, then dunk prior to the first flush for maximum hydration.

Check the quality of your spawn for contaminates. An easy way to keep track of things is use spawn that all came from the same master. That way when something goes wrong you can track it back and eliminate one possibility. 28 quarts of spawn to a single brick of coir is just outrageous. Stick to 5-7 and you should be fine. Here is a great coir recipe that has served me well, good luck.

I usually use 14 quarts to a brick, but I thought I needed more, thanks for the advice. I never thought it was the coffee. I thought a cup of lime was alot and more than enough to kill the acidity, but I hadn't tested the water from the pasteurization yet. I will try this out next time!
