Measuring FAE
    #18801851 - 09/05/13 02:19 AM (10 years, 5 months ago)

So i created a dubtub and am not sure how i can gauge the FAE.

A friend made a thread a while back and someone in it commented that if you have 'clear rings' around your polyfil then that is a good indication of FAE to RH ratio.

How true is this? I have very loosely put polyfil in two of the four top holes and the whole top tubs face (about 6x6 inches) is clear. The other side (again the upper hols) are packed more tightly and just have about 2-2.5 inch diameter of 'clear rings' around them.

should i make both top sets of holes the same, or should this provide adequate FAE and RH???

Thanks

I am using Tyvek on my lids and was wondering about the gas exchange with the Tyvek so I will be keen to see an answer from one of the resident shroom Gods.

I have never run a dubtub but I would just stuff the holes near the sub level as tight as possible and the upper holes very loose like a mono

And yes little dry rings around your lower holes is a good indication that things are running properly.

Btw hows that tub looking? Any pins?

no pins yet. maybe i'll upload a pic in a couple hours.

I just tried to restuff it, it seems like in order to get the polyfil in, its gonna have a minimum tightness, if you try to stuff it looser then it simply wont work (maybe my holes are too small).

should i have dry rings on upper holes, too? or should the upper holes be dry all around? Btw my holes are about 1/4" diameter.

I think those holes are too small psil. On a mono we make like 1.5 diameter holes. I know it isn't a mono but it is pretty damn similar.

On my monos the top holes have a large dry place kind of running down the side below them

Re: Measuring FAE [Re: Stromrider]
    #18803853 - 09/05/13 03:48 PM (10 years, 5 months ago)

let me try to be more specific about my dubber that i have.

Its two identical square-shaped storage containers. The total height is ~8" and the width is ~7" (same with depth). So, its basically a MINI-dub.

The substrate is about 2-2.5", so from the top of the substrate to the top of the dub is ~6". as i said before the holes are 1/4"

It seems impossible to loosely stuff the top holes to the point where there is very little condensation (i messed with it after i made the OP) and the dry circles got smaller..

so, i'm wondering.. would you advise against just taping a square of paper-towel over the holes? Perhaps that can allow more FAE -- would it be problematic as far as contaminants go??

Thanks psilly!



*edit*

So i found a two pack of these bulbs for $10. It says 'light appearance' then '6500k'.. so i'm wondering if appearance is actually the same thing as the wavelength. I know, i'm complicated... but i'm poor and cant afford to spend $10 on lights that wont 'work'.

You can judge FAE by the characteristics of the mushrooms, whether they're showing signs of CO2 damage. Similarly with particularly low RH you'll see signs of that on the mushrooms as well when they develop. You can also judge FAE somewhat by how quickly moisture is evaporating if/when you're misting.

As far as contaminants go having good fresh air exchange is most important thing you can do to prevent them and because of that filtering can actually be counterproductive in preventing contamination in fruiting chambers if it hinders FAE.

So just a thought but you could use wax paper loose on the top holes. That would allow you to measure anymoisture that is making it through the fill. As far as fae in the tub, you can get an so2 meter it will measure the oxygen levels inside the chamber. It has a little tube that you can place through the bottom hole and it will give you Sulfur dioxide and the oxygen levels inside your dub. Btw if you have sulfer dioxide you have way more problems the fae. Lol....

thanks for the info sockadin! Unfortunately i need a more economic means of measuring.

Psilly, i'm back with some pics. I'd love your feedback. Also, did you recently support? Or am i just late on noticing your name colors? :smile:


This is from the top of the tub. It's got condensation so the photo clarity isnt prime, but its quite less condensed than some pics. hopefully you can see it. The mycelium looks ready, no??



This photo is through a bottom hole. the polyfil is in the hole but there is a dry-ring and thats what i'm shooting the photo through. again, mycelium looks good to me.

Unfortunately its hard to take a good photo of the dry rings, but it seems to have less condensation than it did last night/earlier today. Again, the holes are about 1/4" and one hole on each side of the top have no polyfil. I'm not sure if thats too much FAE or just right, considering my hole size.

my biggest concern is not knowing the internal humidity and temp, and i dont wanna open it. I've got a 24" fan about 10 feet away, on the floor pointed in that general direction (tubs are about 3 ft from the floor, on a dresser)

Thanks a bunch.

I think that myc looks happy and healthy. I think I would leave the polyfill out of those upper holes for sure. Being that small that is the only you are going to get good fae. With bulk subs good fae is more important than really high rh.

Next time just do a mono. It will be easier for you and there is a shit load of good info on here about them. Just read frankhorrigans write ups.

Oh and yeah I bought a supporter account this morning

so most of the condensation is going away, what does that mean? The rings around my bottom polyfilled holes are large. Seems like too much FAE is drying out my FC. However, i still see small droplets of moisture on the substrate. I see what im guessing is knotting, but i cant tell if drying out would also give some similar visual cues, or not.

would it be safe if i misted a little bit in one of the pfil holes?

Stuff the bottom holes tighter, and the top holes looser.

Yes exactly .
A shotgun with holes on all 6 sides will let the natural air movement keep the fae up thus lowering co2 levels.

As long as you did your dub tub to tek it should work ok many people have great luck with it if they have room for them but they are not a necessity and a well build mono tub with 2 - 1-1/2 in holes on 4 sides work great and take up much less space. :grin:

As long as your holes are placed on all 4 sides and you are fanning them more than ones a day you will be just fine. Watch for the low O2 signs.

Okay.

I feel like i'm asking a lot of questions. i did this with my oysters, too. Then my oysters fruited and i have another batch (take a look here and here!) and feel like i can do oysters with a blind fold on (i'm sure they're easier), hopefully after today my other two mono's will be a breeze (however i'm doing a hole-less tek i found on here).

Anyways, here are pictures of my whole deal. Im under the impression that --tub size matters, and mine is definitely a mini.

This is it in its entirety. I used a flash and i think it made the middle of that one face look like it has 0 condensation on it, but i'm pretty sure its all covered with condensation. Also, you can see a rip on the bottom -- i used blacked paint instead of a bag and it peeled off (d'oh!)


Here are four polyfil holes. Before today i had one of the top holes empty on this side, and the other side. The condensation rings are what i would assume are optimal (not too much not too little?) You can also see some rings on the bottom holes (and a paint-tear). Yes, where the two tubs meet, there is an absence of condensation (the whole perimeter is scotch taped). The other side (top) has much bigger rings (almost entire window is clear)


This is the contents. It looks like its starting to knot and you can also see some glistening from the moisture. It seems to look okay to me (hard to tell how moist the coir is, though). Also, some of the knots are somewhat yellowish -- i'm not sure if thats drying (i'd assume that dried mycelium would turn blue) or something else. the yellow is sparse and very subtle (not visible in pic).

i think plugging the holes more helped. i now have pins. from this point on i think i'll take this project over to tbags thread, as part of his grow-along!


Thanks for the help gentlemen,
P. Bonsai :crazy2:
