    Hey everyone, i have a couple of bulk substrate bags that i am going to be putting into fruit . I am prety new to fruiting in bags as iv just switched from using a monotub to some unicornbags with .5 micron filter for gas exchange. I have been having some success but i know the potential yeild is much higher than what i have been getting. I have a good temperature control and a small fruiting chamber that i can bring up to 95% rh so i dont think that it is my problem. I am wondering if anyone has tips on getting the best pin set and flushes with a bulk substrate bag(8lb bag). I normaly just poke 6 to 8, 1/4 inch holes in the top of the bag to drop the co2 when i am putting them into primordia. My lights are all as well so i am curious if i am poking to many or two few holes in the bag, or missing some other detail that can maximize my yeild.

    In my experience using mycobags, normally once they are fully consolidated, primordia will form without really doing anything. What I would suggest though is to make sure the room temps are in a decent range and turn on a fan, oscillating if you have one. This should slightly increase gas exchange via the filter patch and you won't have to worry about anything drying out.
    - It's a bit tricky to keep an eye on the progress and make sure you don't have a bunch of overgrown, lanky pins. As soon as you see a good pinset forming, I would put them right into your fruiting chamber. If you are putting the bags in your FC with only holes poked in them, they aren't getting enough fresh air exchange. Make sure you at least fold the sides down or if possible you can pull the bag off entirely and place into a FC.

    As long as you have good humidity levels 90-99 RH and some kind of fresh air exchange like a small fan inside to circulate humid air and allow fresh air to passively enter I believe you should have pins on all sides of your substrate if you have shelves that are a grid and not solid.

    I have seen people cut a small slice in top corner than as the flushes flush you open it more and more so first harvest would completely open the bag then you wait til next flush then cut the bag down half way (or you could keep it whole not my experience) but then towards the end your fruiting Block ends up completely out of the bag. I have recently started experimenting with unibags too .2 filters with a hay coco vermic and grain at bottom and I innoculated 10 days ago but I still have my money going too. Can I ask what made you ditch your mono?

    Here’s a question Do you add moisture to the substrate mix before injection or do you just inject and shake the bag to distribute. This is my first time using bulk substrate bags. I’m about to start the process but first I want to know what I’m doing first. I’ve up to this point never done anything with a bulk substrate mono tub or bag. So I guess I’m butting in on your conversation hoping to get some understanding Thankyou

    I've only used em for a short time also I'm still trying to figure em out I've just been searching bag tek and species I am going for and trying it their way and tweaking it as I go so I can figure how it works for me just paying attention to everything very closely

    My bags are only about 2 lb and I was wrong, no injection port. Has a filter patch and is vacuum sealed at the top and above the substrate. I’m going to do my uncle bens over as I totall y did not read instructions. I used a whole syringe, way to much moisture. Meantime I’m going to inject the bags and polypore over the injection sit. When done I will break the seal above the substrate and let them grow

    I just injected 15 ml of cube spores onto the substrate. If nothing happens then I will use the Uncle Bens spawn when it has colonized. I totally am a rookie and always looking for the easy way. I’m basically just searching new reasearch.

    Guess I’m tweaking as I go along too. I have Brocken the seal above the substrate and the top of the bag. We will see what happens. Also I googled uncle Bens tek. One guy on there does all of his spawn using uncle Bens for spawn and has amazing results Growing shrooms cubensis. Much easier than the grain. He even does the agar thing with his spawn from UBens

    I got a buddy that does that too I just get 90%of my supplies from my local farm goods store so I buy almost everything 50lbs+ easier for me and easier on the bank also imo. But yes just like am inch or so of coco coir. And yes right below seal line then fully open after 1st harvest then cut the bag down every flush and until it is eventually not in bag anymore. That's how I've seen it done. That's how I'm trying it.we will see. I'll post any tips I figure out along the way!

    The bag is fully opened. I dropped the spores, without the needle on the syringe, right on top of the substrate, I used some mycelium off of a few agar plates also. The agar itself had dried up however the mycelium was still there .I used a sterilized scalped to scrape it off into the substrate. Don’t know if it’ll work but it’s done ,so I wait.
