Using Spawn Plugs In Bags?

Surprisingly I didn't find much info using the search tool. Obviously many types of gourmet mushroom spawn is available in cheap plugs for logs. It seems like those plugs could just as easily be used to spawn a bag...right? Obviously I'm not the first to think of this so there must be a reason it's not used in that fashion. I just can't think of it.
To low of spawn ratio? Not sterile?

If you take non-sterile plug spawn and use them in a sterile bag of substrate I very much doubt you will get good results. You can use them in pasteurized substrate probably. They're just not really ideal for various reasons so why use plug spawn for bags? But if you happen to have a bunch of extra plugs around you can spawn them to some pasteurized substrate.

I've never purchased a plug so was unsure if it was sterile or not. My reasoning of thinking of using them if possible was ease of use and price. At $30 for 1000 plugs if you could just toss 3 or so in a pasteurized bag as opposed to growing out the spawn with the time, cost and space it takes it would be ideal.
If you don't mind elaborating on the various reason's it's not ideal I would greatly appreciate it.

You mean $30 for 1000 blanks plugs? Using plugs wouldn't change your spawn rate. If you use a quart of grain spawn you would need a quart of dowels. Probably a lot more because 1 reason grain spawn is better is that there is higher surface area per volume so more inoculation points. You wouldn't be able to just throw in a few plugs and more than you could throw in a dozen colonized grains.
Also I would think the nutritious base that grain spawn provides would give the culture a better jumping off point for the final substrate. I have no proof of that so take it as you want.
I don't want to talk you out of it since I've never tried it. For me grain is very convenient. It fits well in quart jars and shakes up nicely and can be prepared quickly. I go through a a 50lb sack of grain pretty quickly so it's convenient to just get another big sack from the store rather than ordering another big heavy bag of dowels.
But like I said I could be totally wrong so go ahead and give it a try

I've just been asking a friend a similar question, except i wanted to go dowels to grain. Apparently not the way to go (although these dowels may be contam free) they are old and apparently the best thing to do is add one to a tray of peroxide agar. Sorry, one dowel to one dish, times many.

Not sure if I'm allowed to post links to non sponsor vendors but they are $30 for loaded(?) plugs. http://www.mushroompeople.com/products-page/spawn/oyster-spawn/
I was watching this video that was posted here and the commercial Shiitake growers only used maybe a 1/2 cup of spawn to 3.5 lbs of sub. That's what got me thinking it may work with a few plugs. I know typically we use 1:4 +/- but it worked for them so it got my wheels spinning.
About the nutritional value, with only a 1/2 cup or so I doubt much would be added. Besides, you can enrich your sub to make up for it.
Maybe I'll order a few for shits and giggles.

these bags of Maitake were spawned with 2 year old Fungi perfecti dowels in sterilized substrate I used probably 10 dowel's in a half gallon jar of sterile sub first ...then used that to spawn the bags have done similar many many times (also made LC with the same dowels)
hope this helps MOMOFO

Using spawn plugs will work fine, just use a little extra water because its a much longer colonization. With grain, each and every seed does the same job as a single plug, so its thousands instead of a few. Much quicker.

Nice. How long did it take to colonize the 1/2 gallon jar?

The longer colonization time makes sense as the biggest issue. But on the video they used very little spawn for their commercial grow. If you aren't getting contams with the longer turn time then on a commercial scale it shouldn't be an issue. If you always have a large inventory rotating for harvest then it would take longer for the first harvest but there after it should be fine.
