Set it and forget it zip bag FC setup with passive FAE? * 1
    #27012109 - 10/30/20 01:08 PM (3 years, 2 months ago)

I want to use a zip bag FC that have a passive FAE, holes covered in micropore tape. And that dont require to manually air out the bags every 4-6 h. My question is, have you have previous success growing in zip bags like that with no need to air out the bags? Trouble with lack of FAE when fruiting? :smile:

I use this today but have no passive FAE. Using one filterbag from factory with stripes of filter across whole bag and modded zipbags with MP tape holes. But right not i need to air out bags every 4-6 h. I want as close as set it and forget it, i saw 1 user said that he had passive bags like this.

And how many holes is preferred, with how many layers of MP tape?

Pictures? Please :grin::heart:

Thanks!

Do you mean a tub within a bag, or the substrate directly in the bag?

Can you edit your original post and remove the ‘tek’ symbol. . . This isn’t a tek 😊

I'm pretty sure they are referring to this:

Sorry english is not my first language and im new on terms, im using a brick sized plastic box to grow in, and have that box inside of a growbag like described :smile:

Simular to this but with stripes of filters across whole bag, still not enough to make it passive fae:

Yeah i actually was referring to this pic from pic of the day thread or what ever it was. Dont see any holes, how does that work?

Im curios how passive you can make a modded zipbag. That would be awesome and didnt even think it was possible. Know where i can read more about this?

If you have a similar setup please share picture :heart:

Also what is PEA+? Passive Exchange Air+? Haha :grin:

For passive FAE, it's not necessarily the amount of holes/patches that you have, but their placement. CO2 is heavier than fresh air, so it sinks to the bottom of your container. If you have holes/patches on level with the base of your cake, and another hole/patch at the top of your container, you will have circulation (CO2 out the bottom, fresh air through the top). The only trouble with passive is getting your humidity levels on target. Passive FAE may inadvertently carry out too much humidity with it, so that it's not truly "set and forget."

It's all possible. With some experimentation you can likely get everything balanced. It just varies so much from person to person because of your local ambient humidity levels, temperature, airflow, etc.

PEA+ is what fahtster was calling an attempted cross of Penis Envy and AA+

I think he said he pokes small holes using a syringe needle, and just watches it closely to determine if more or less holes are needed.

Mnemosynea, CO2 doesn't sink. If it did, we would all suffocate. But it does concentrate around the fruits, where its produced. Its kind of splitting hairs, but just thought I'd point it out.

One of Us, it really depends on ambient factors. In any normal environment (in a home, outside, etc.) CO2 rapidly diffuses into the atmosphere because of Brownian Motion. However, in an environment without airflow (like a silo, a grow bag, or a still air box), the CO2 will sink.

If interested there's a great dialogue about this between physicists and students here:

If CO2 Is Heavier Than Air, Why Doesn't It All Sink To The Ground?

Exactly what I said. In a silo the co2 concentrates around where it is produced, just like it would in an unmodified tub sealed tub. But it is always slowly mixing. Its just it gets produced faster than it diffuses.  The mass of co2 isn't really a factor.

The co2 diffuses very quickly outside due mainly to wind rather than brownian motion. But brownian motion is mainly what causes diffusion in closed containers.

Unmodified tubs work fine despite only having only a cracked lid only allowing air exchange at the top.

Here's a diagram of a common experiment done that shows how gasses of different molecular weights mix in an closed container. But keep in mind, a good fruiting chamber has good FAE, so it diffuses co2 much faster.

I’m very curious about this, especially with species that require much more FAE. For those, a tub with a cracked lid isn’t enough, which I assume means there is some notion to CO2 pooling near the surface of the substrate. I’d like to do an experiment where the grow is suspended high up in an enclosed space, where the only FAE is at the bottom (the opposite of the “cracked lid” tub). I think this would clarify whether CO2 is “sticking around” where it’s made, or if it hugs the surface because the surface is the lowest point in a typical tub. From what you’re describing, I think the result would be equally insufficient FAE in either enclosure.
