Water absoprtion in BRF cakes -[EXPERIMENT]- 7

EXPERIMENT To determine exactly how much water a fully colonized 1/2 pint BRF cake absorbes during dunking process.
Four BRF cakes were used in the experiment. Before weighing, each cake was thoroughly rinsed in cold tap water and wiped dry with paper tissue until no more moisture could be extracted from the cake with the paper tissue.
The weight of the cakes throughout the 24 hour dunking process: After Birth 73.4g 77.4g 90.9g 80.9g
After 3 hour dunk 81.0g 87.0g 97.8g 89.3g Water absorbed 0-3h: 7.6ml 9.6ml 6.9ml 8.4ml ~ 2.71ml/h/cake between hour 0-3 After 6 hour dunk 85.2g 94.8g 101.8g 94.7g Water absorbed 3-6h: 4.2ml 7.8ml 4.0ml 5.4ml ~ 1.78ml/h/cake between hour 3-6 After 12 hour dunk 90.1g 100.0g 108.1g 99.5g Water absorbed 6-12h: 4.9ml 5.2ml 6.3ml 4.8ml ~ 0.88ml/h/cake between hour 6-12 After 24 hour dunk 94.2g 105.1g 113.2g 103.6g Water absorbed 12-24h: 4.1ml 5.1ml 5.1ml 4.1ml ~ 0.38ml/h/cake between hour 12-24 Total ~water: 21ml 28ml 22ml 23ml
Hydration after 6 h: 56% 62% 49% 60%
Pics below are of 20ml spore syringes next to BRF cakes to help put into perspective how much water the four 1/2 pint BRF cakes absorbed each within the first 6 hours of dunk:
Cake 1 Cake2 Cake3 Cake4
(The one and the same cake was used as a model in these 4 photos, but main point is the syringes)
This is how much water cake 2 absorbed in 24 hours
Here is a graph that MegaCrouton made

Hope someone can find joy or use from this experiment, I intend on continuing this experimenting and extending it to compare mass vs surface area when it comes to hydration, to investigate bottom watering or 'low surface area watering' instead of dunking and submerging cakes to hydrate them to field capacity. We'll see where this ends Updates will come for sure.
PS: I know Leopardman did a similar experiment some years ago, I was just curious about exactly how much water a BRF cake 'sucks' up and LM's experiment really didn't tell me that. Also I had already started on this experiment before I learned of LM's post so let's just call this an 'update' on BRF water absorption science

Very well done mate Actually awesome. So you basically had very similar results to what I had at the time. First 12 hours seem paramount in terms of water absorption

Went out today and bought 24 jars plus 30 since before that are colonizing right now (testing clones) and now I'm gonna experiment with the PF Tek recipe as well to see if different amounts of water in BRF cakes gives different colonization times.
So much fun information to extract from Pf Tek alone, can't wait til I get more comfortable around grains and start experimenting in that department too. Much more stuffs to come.

PF cakes are the way to go if you like to experiment as much as I do Less water content always tends to give you faster colonization times.
Not sure if you already checked one of my old threads but it might interest you.
Good luck

Thanks again! Interesting post btw! Looks like I have to read up on some more of your work!
And maybe also build a heat bomb

I know this is an older post but I felt compelled to say...Thank you so very much for this research you did! I'm a noob grower, on my first jars now and just started dunking. This was EXACTLY what I was trying to find out. I'm willing to bet if you were to leave them dunked for another 12hrs the water absorption would have halft again. It seemed very linear, almost predictable in the amount of drop off from one time to the next. Now I know the last 12hrs is minimal. Awesome job!

I´m glad you found this post helpful, that was exactly my intentions when I made it As a curious noob and knew there was gonna be an endless supply of curious noobs wondering about BRF cake hydration. Wonder no more

Thank you for the write up, very insightful!
Curious about your soaking method...did you place in bags/containers or submerged and weighed down?

Sorry for replying to an old post (but also, I don't really see the problem with doing that ).
I have a question: With the figures you gave us, it is almost certain that leaving them for even longer still would result in even more water being absorbed. It almost seems like 24hr is not getting close to saturation, considering the "hydration per hour".
Has anyone done this experiment on more than 24 hours?
Is there such a thing as "too much water", as a result of the dunk and roll step?
Is there any problem with leaving them in for longer than 24hrs (like they "suffocate" or something)?

Well if you notice from the calculation how absorbtion slows down drastically/exponentially then the conclusion is that soaking for more than 20-24hours is pretty pointless, you're not gaining much more in term of potential fruit production instead you're increasing the odds of bacteria gaining momentum from the prolonged high moisture contents inside the substrate. This is my take on this at least. And to be honest after a 24h soak you can really feel that the substrate is on the brink of being too wet and soggy so I wouldn't recommend soaking longer. Tho I have to say I have in the past forgotten to remove cakes from soaking only to discover them weeks later busting out of the container they were dunked in and shooting out these thick lush mushrooms all over the place, the cakes themselves looked like death but they still definitely benefitted from all the extra water around them when they fruited. It's actually funny that they basically fruited in open air and most of the fruits grew out to big mature fruits without dieing.
