myco bags filters and heat damage
    #22106394 - 08/18/15 11:43 AM (8 years, 5 months ago)

I was reading that RR had problems with myco bag filters. I use large bags that are pre-sealable and I PC them for 2 hours, because the bags are so big. Should I worry about filter failure? RR said the bags had cheap thin filters and he was moving back to jars. Is this still true? I love bags. I hope to keep using them. T

Depends on the bags you get. Unicorn bags are crap IME.

I get mine from Shroom Supply. I'm excited to restart my monotubs after teaching myself agar - but I would like to not add a contam variable.

My bag filters were extremely resistant to air flow. I cut holes in some and siliconed on the filters I use on jars. I left enough area on the original filter so the silicone stuck well, it gets into the fibres of the filters. If you try and silicone filters to bags they easily fall off, you can roughen the plastic up to help it stick but they can still come off.

How can you tell they are resistant to airflow. Gut feeling of the pace they are colonizing?

I've cut the filters and stuffed them with Poly before. This is an awesome idea though.

I have a hard time believing good bags don't exist. Don't commercial growers use these all the time? They don't jerryrig the filter, right?

you can stick your mouth over them and try and breathe through them, or in my case I could not. Also I would microwave the bags and they blew up like balloons and would let very little steam out. My other filters would let steam out easily enough. I am not aware of the micron size of either.

If the bags were filled with water little or no water could pass through the filter. And the bags I did grows in did stall which I put down to poor air exchange. When I put my own filters on things improved.

Aloha has ones that look badass, but they're pretty expensive.

I've been using unicorn bags for more than a year w/o issue.  many many many bags.
the aloha ones are expensive, i agree.

Those Aloha bags look amazing, but I wonder if I can pre-seal them? Because they make no mention of it, I assume no.

I also wonder if more careful handling of these bags can help cut down contams. I've heard to avoid touching the filter, but what about placing them in a very clean environment. I've been doing this hobby for years, and I'm at the point that I'm not worried about visible contams, I'm worried about reduced yields from hidden contams. I want the best mycobag process so I can experience clean growth and high yields.

You really shouldn't pre-seal any bags, even if they say you can. I've had all kinds explode.

they won't mention it because they would never do it.

careful handling of anything will cut down contaminants.

I like the unicorn 3t bags.  price and quality are good for me.  the myco sac bags that aloha uses feature a different kind of filter, so they're a bit more expensive.  but, according to aloha and that company, it does filter better.  but, i've not had a unicorn filter fail unless it got stuck to the bag during PC cycle.  i use a peice of tin foil sandwiched btw the plastic and the filter thats folded over to prevent that.  IME, the impulse seal at the top is the weakest part of the bag, not the filter or the bottom.

are you growing cubes…or?

I have presealed bags and afterwards punctured them with a pin near the top before heating. So it can vent itself easily and when I take the bag out I know there is only a pinhole -and I know exactly where it is, you can circle it with a permanent marker. So after taking it out carefully I can reseal the pinhole. Its easier than handling a bag which was left fully open. I have also just sealed most of the bag and left a good sized area open in one corner.

If I have an injection port I can stick a needle into it during heating, PC and let cool, then the moment I open the PC I can take out the needle. Similar sort of idea.

I'm growing cubes. I've been pre-sealing these shroomsupply bags many times with no explosions. I seal them three times, and do gentle shakes. I found messing around with wet, unsealed bags completely unsterile and hopelessly clumsy. Things are a ton better now that I pre-seal. I have no flow hood and inject LI into the bags. Maybe I'll put the noc'd up bags in a clear clean tote. I also wonder about whether the grain should lay sideways in the bag, allowing the air cavity access to more grain surface.

Blackout. I like those tips. They make a ton of sense.

when the bag hits about 30-40%, i shake it, and then lay it on its side to finish. 
for me, its a matter of preventing too much internal heat up during recovery

right, theres the heat too. It will be a hundred tomorrow where I am.

I wonder too if people have experimented with airflow near the bags. I was suspicious that too much of this caused some of the dead/dry areas on some of my bags.

blinding leaf... I also see you roll over the top of the bag, which has helped me with strengthening the bag when shaking.

I still like the idea of during PC cool down, the air coming back into the PC, then into the bags going through a filter. Wasn't it RR that stuck a sock in the bag for this very reason? (not really a sock)

yup yup!!  i actually roll it because, like i said before, IME, the impulse seal is the weakest link.  the only time i have gotten con tams was from a breach in the seal over time.  so after i seal it, i fold it tightly twice, then tape it with a few pieces of scotch tape, or whatever is on hand, then i "tumble" it around to shake after g2g.

i don't think air flow will really affect it, but i will say that the drier the air is in the room, the more uncolonized kernels u will have at the top, similar to a grain jar that was filled too much.  the size of the filter may affect that too, but i only use the 3T bags, so i can't speak to other filter sizes from experience.
