Hahahaha- heard your voice before I even saw the name on that post! Good to see you on here buddy :wave: - I've been bragging about y'all, :lol:

So if you sterilize the alfalfa, what keeps it from contaming when you mix with pasteurized straw into logs? I know you don't do all of that in front of the flowhood- or is this a different process than the bare handed mixing of colonized grain and straw that y'all did a video of? Sorry but I'm terribly confused- wouldn't sterilizing as opposed to pasteurizing actually make it more likely to contam as you spawn in open air? Or do you colonize the alfalfa first then spread it to straw?

Damn bro, those look very nice. We'll have to try the pasteurizing method. Looks like its working great:thumbup:

So, no we spread the sterilized alfalfa in a non-sterile way, at the same time adding gypsum, mixing it with our hands and stuffing it into tubing. We do end up with some contamination, probably 1/8th which I can happily live with.
That is a good idea though and I think I'll try it that way (colonizing the alfalfa under the flow hood then spreading to straw like we would grain spawn) and see if the mycelium grows through alfalfa.

But I really pulled this thread up to post this picture of blue oysters (Aloha's O12a) the lighter colored one grown on straw with alfalfa (method described by speaksoftly) and Sawdust supplemented with rice bran.

Right now we are doing it how you said. Sterilizing, laying pasteurized straw on a table, adding gypsum, then adding the sterilized alfalfa, mixing then stuffing into our columns. Adding a layer of sub, then a layer of grain spawn.

I see what you mean about making it more likely to contaminate. It has been working pretty well maybe 80% success rate, but I do like the idea of just adding it into the bags when we pasteurize. Gonna have to change a process or two, but I bet it will save us a lot of time in the long run. Thanks TravelAgency

That's really interesting, straw vs sawdust!!! Those are some incredible differences!! Any other differences in the process that could also account for it?

And thanks! Glad I could help y'all for a change- y'all have done so much for me! Let me know what kind of difference it makes! Currently taking a break from using my shiny new flowhood! Banging out a lot of work tonight! Oh- and I don't know if the Lipa made it- doesn't look right- but I dropped it anyways so we will see.

Also looks like perhaps my fridge wasn't cold enough, or the cultures I've had have just been in there a loooong time. All the cultures are shrunk and dry looking- guess I'll be doing some emergency transfers over the next few days. I hope they are still good. One of my King clones actually took over almost half the entire interior of the glad mini round!

I digress though- always look forward to the knowledge you share!

Edited to add:

That's also interesting because my unsuplemented pasteurized sawdust gave me fruits more like your straw- (could it be the bran?)

pardon my ignorance but can alfalfa not be pasteurised with the straw?

Yes, most pasteurize it.  This is the first I've heard of this method. Sounds like a sure fire way to contamination...not sure why it's being done. As long as it's spawned heavily it should cut that risk down due to decreased run time.  Nice looking crops though!
