Grow Bag Pointers 2

I keep seeing questions popping up regarding grow bags, mycobags, grain bags, whatever you want to call them. First off, not all bags are the same as far as how you can use them. Bags that contain only grains such as rye, millet or popcorn are spawn bags regardless of the vendor label for them. They may grow a few mushrooms invitro, but these bags are best suited as grain spawn for a bulk substrate or to be broken up and cased. They simply don't hold enough moisture to produce decent flushes.
The bags that are intended for growing mushrooms invitro combine grains with ingredients that are able to retain moisture such as vermiculite and coir. These are the type of bags found on www.themadseason.com and a few other vendor web sites.
I keep seeing posts with noobs asking "why haven't I seen growth, it's been 3 days?". Well, if you injected your spores in the center of the bag, the mycelium will have to grow from the inside out and will take time to be visible. Every time you handle and squeeze the bag looking for the mycelium, you are shifting the substrate around and possibly damaging whatever mycelium may be present. Impatience here will cause more problems.
Another thing I keep hearing from noobs and veteran growers alike is that multispore inoculations won't work with these bags and that you need a liquid inoculant. This simply isn't the case in my experience with the mad season type of bags.
My personal recommendations:
- Inject your inoculant along the sides of the bag like you would a brf/verm jar so that you will see growth along the sides as soon as it occurs. This should help you not freak out when growth doesn't appear within a week.
- DO NOT mix the substrate around after injecting your spores. Wait until you have 30-40% colonization or more, THEN mix the substrate around to mix the colonized with the uncolonized portions, then leave the bag alone until colonization is complete.
- LEAVE THE BAG ALONE for the first couple of weeks. This goes back to the point I made earlier about damaging whatever mycelium might be growing within the bag.
When I used the bags, I would inoculate them and leave them in a closet for at least 3 weeks before I even looked at them.
Anyway, here are some old pics I dug up to show that the bags will work using just spores and a little patience:
  
  
Toilet flush simple if you follow the directions and leave the bags alone

One more thing I forgot to mention. Occasionally the bags will be very tightly packed like they were vacuum sealed or something. If the substrate in the bag is like that when you get it, give it a massage to loosen it up a bit before inoculating. This will allow the myc to move through the substrate more easily and speed colonization.

Can you inooculate them, leave them for a month, when fully colonized cut the tops off the bags and put them in a styofoam cooler and they will just fruit up from the bottom of the bags like those pictures?
On that website, they sell 1pound bags.. if followed the above mentioned method what is a conservative estimate of yield per bag? Would it be similar to PFTek.. or larger yields?
Im just trying to figure out cost effectiveness of these bags vs cakes

Figure an average of half an ounce dry total per bag.

you could do that if you wanted, but theres really no need. the bag already has the proper humidity in it. it makes it very easy
what is in those mad season bags? i usually make either a totally grain bag for just spawn, or just a poo or coir based bag. is it just grains and verm?

All that TMS states is:
Quote:
Our Grow Bags, also known as MycoBags, contain our own grain based mix. The Grow Bags contain approximately 1 pound of substrate each. The bags themselves measure 18" H x 5.5" W x 4" D. They can be used to grow many types of mushrooms within the bag or can be used as spawn for a bulk substrate. They are pre-sterilized and include a self-healing injection site and a filter patch to allow for gas exchange. Mushrooms may be grown inside of the Grow Bag or you can take the colonized substrate out of the Grow Bag and case it with your favorite casing mix. All that is required is a spore syringe. Our Grow Bags are a great alternative to many of the other overpriced mushroom growing kits on the web today. Check them out to see why it doesn't get any easier than this!

Good write up, but I guess I'm still confused/curious about these bags. From what I under stand, you don't need any tubs or chambers. You just let the bag do its thing in your closet. Am I off here? Or do you still have to incubate and place them in a fruiting chamber?

from the looks of them, theyd be great to spawn to a bulk sub. fruiting them might not give you too much.

Sorry for bumping this but I need to know if I should cancel my order! I ordered Mycofactory MyShroominBags and I need to know if I'm gonna be able to fruit in them, after I read this post from Fooman.. Here's the bags I ordered

Hey, sorry for necromancing this thread, it has some very useful information and I figured it'd be better than making a new one.
I was just wondering if you think it would be possible, and if so, worth it, to make up a grow bag from oven bags? Is it a different material or a different shape that would prevent it from being as effective as a vendor bought bag? Thanks for you replies.

There was a tek I think with oven bags. The guy used one big ass bag for the grow and knocked it up with like 10-20 cc's. It is possible and I could see it working. You could use a ziplock if you got it sealed and it survived the PC. I had a buddy make 1/2 pint jars of WBS for no other reason than G2G xfers. 1/2 pint of white ropy WBS in a fresh bag of about 2 quarts WBS and they take off like mad.

I was thinking of 'noccing up some pasturized hpoo and/or coir with some colonized pf jars. (I don't have a pc....yet) I'd just boil or bake the bags full of substrate to pasturize. Think it'd work?
