 Grains and nutrients

Hey everybody, first time poster here. I would like to pick your brains a little bit concerning grain spawn, to be more specific grain spawn to accompany plain Coir/Vermiculite/Gypsum.
When I first started growing I would use wild bird seed, I had a good clean source heavy on milo with millet and a little wheat. Even when I was a new grower and with MS I was hitting yields at about an ounce a quart of spawn like clockwork, with my main clone I had been hitting 10 ounces per 8 quarts of spawn first flushes.
Well, I had lost my source of good bird seed and started purchasing rye, which I love working with, simple, clean, comes out perfect every time, but there is an ABSOLUTE clear difference and decline in yields while using the same volume or weight as wild bird seed when spawned to straight Coir/Verm/Gypsum, sometimes yields are down by half. Every tub and every grow that I am basing this on has all been from the same isolate, I only keep the spawn through 3 generations and take it back out from slant and so on, so it's always very fresh.
So recently I finally sourced some good bird seed, and my yields went right back to exactly what they were before I stopped using it and switched to rye. I always suspected the rye was reason for my declined yields and finding a new source of bird seed confirmed that.
Now out of my experience with different mushroom species and substrates, this is only something I have seen with Coir/Verm/Gypsum leading me to believe that the nutritional value vs. starch of the small seeds is far greater than rye grain which I am taking has more starch less nutrience per grain.
I hate working with bird seed, its a pain in the ass! I need a grain that is easy to prepare that will give the same benefits of the bird seed. I am going to the feed store and buying a few different things, I have read about the race oats a lot, I am going to pick up a bag of that and compare the yields as well as a bag of straight whole millet.
I want to know about your experiences with yields vs. type of spawn and what you guys are finding best for coir. Thanks for reading, I am happy to finally get into the conversation with you guys after reading this forum so long.

WBS, rye, oats, etc.. doesn't matter. yield tied to genetics and environment way more. you should expect about 1 dry ounce per quart of any kind of grain spawn when using MS if you got conditions right and up around 2 ounces per quart with a good performance culture(clone or isolate)
if the grain choice is making a difference for you it's because you have only got a few grows under your belt(less than say 20-40). the variation is falsely attributed to ingredients

Oh no, these observations were from a single culture at least 50-60 tubs of it, rye and wbs perform the same for gourmet mushrooms on supplemented subs for me that's why I notice this when going into a sub with less nutrients. Also my culture was a clone chosen from lots of testing, and lots of culturing so it's not the culprit, it's not my only culture just my working culture so it has had lots of recording and different conditions.

ok then, since you know why are you asking
generally for cubensis. less nutrients generally helps

I am curious if anyone else has noted the thing, Im not saying Im right, it's mainly after I grew some shiitake bags and did some bags supplemented 5% with wheat bran and 20% with wheat bran, yields are day and night on supplemented substrates, that's why I had the notion maybe sometimes grains play a role in yield, obviously they do by higher spawn ratio, but maybe the actual grain itself can play a role? I just wanted to pick brains about the subject.
Amycel sells specially enhanced grain spawn, synthetic too, I never really gave that too much of a thought though.

That's what I was also confused about, thanks I wasnt sure how different it was from agiricus cult in that aspect.

Maybe it has to do with weight, when I started using spawn bags I started weighing the bags, I noticed the WBS weighs way more by volume than rye, maybe that has to do with it, I'm just getting a way higher ratio in my sub using WBS.
I want to be able to start using oats due to it's dirt cheap at the feed store, has anyone weighed out a quart of oat spawn?
