Sawdust Block Recipe for Using LC Inoculation

Hey folks,
I have a bunch of hardwood pellets and wheat bran that I've used to to make blocks. In the past, Ive inoculated with grain spawn, but now I'm getting into liquid cultures. I followed a 5 lb block recipe from the interwebs when using grain spawn:
5 cups wood pellets 1.25 cups wheat bran water
Do I need a more nutritious block when innocing with LCs? Any suggestions? Im growing Lions Mane, Oysters, and Shitakes. Thanks!

grains add a bunch of nutrients, you can actually supplement pasteurized substrate with extra grain spawn. It stands to reason that you may want to add more nutrients for LC into sawdust.
Shiitake would be the only one in your selection that could have a negative effect from more supplementation as its known that shiitake will form mutants and lower yields when supplementation is too high.
As an aside, here is the negative of using LC into sawdust, you cant really tell if the LC is clean before you inoculate a substrate. This could lead to a possible contamination of your entire bulk sub run.
so be careful, nocc an agar plate first to see what grows out but even that is not a fail proof indicator of clean LC.

 I wouldn't recommend using LC as inoculant for sawdust. LC > grain master > sawdust bag. I find that an entire quart jar master works best for 5lb block as anything less takes far too long to colonize, you can go as low as half but it's not worth it imo.

I would use the lc to knock up gars of grain and then use the jars to bulk grain bags. But anyway here is a recipe that I used when I used wheat bran for oysters...

I used this for the chicken manure it has a bunch of micronutrients that really seem to help...

I use a flow meter to put my water in my bags it makes my job a lot easier so the water is in liters be careful with the water though every brant o fuel pellets has a different water content

Thanks for the tips. I did some lion's mane bags with LC to sawdust and it took almost 5 weeks to colonize completely. Its a long time, but not as long as it would of taken to go LC to grains to sawdust bag….At least I don't think.
What does a commercial LM grower typically do? Because I don't imagine they use grain spawn, but could be wrong.
Appreciate the recipe, that flow meter is sweet. What is the proper water content of a sawdust block? I try to hydrate the mix until a very hard squeeze will only produce a small drop of water.

I find sawdust usually hydrates properly at 60% h2o

I do G2G and it takes me about 3 1/2 weeks to go into my fruiting room. So if I spawn today in 3 1/2 weeks my bags will be in the fruiting room. And I do oysters not LM. But I stay ahead of the game. So I always have spawn. Once I spawn, my bags are ready in about 10 days. But I stay ahead of that also just in case I have some contaminated bags I have the next weeks bags that I can use to make up the difference of the contaminated bags. G2G is the way to go in my opinion.
LC is not worth the risk. You know if grain is bad. LC is a crapshoot!!

Yeah, it all makes sense with oysters. You can drop agar wedges in 5 lb bags of grain lol. They tear through everything fast. LC isn't really a crap shot if you verify that it is clean. Its a pretty powerful way to inoculate fast. You can skip the grain master and go straight to bulk grain bags. A liter will easier do 25 bags.

With the amount of volume that goes through farms they use grain spawn bags to inoculate with, but I'm only aware of what 2 farms do lol. I am making the assumption based off of these two, it seems reasonable though that most would follow the same operating procedures for the most part.
Relying heavily upon liquids at the industrial level seems risky to me but what do I know.

If you can get ahold of soybean hulls I highly recommend you do so for the oysters and lions mane. The shiitake doesn't like it though. Id stick with supplementing sawdust with 20 percent bran for shiitake and be prepared to wait a couple months.
If you can get soybean hulls (powder or pellets) mix that 50/50 with the sawdust for best results On the oysters and lions mane. I do 1lb hardwood pellets, 1lb soybean hull pellets, and 3lbs water to make a 5lb block.
On our farm we don't use lc. I don't have anything against it I just feel a lot more confident going agar to grain to production blocks. So I'm not one to give advice on it. Maybe someday Ill fool around with it but not today
We use very little grain spawn to inoculate our blocks and our LM and oysters are ready to go in the growroom in about 12 days
