Have anyone scene this moster before and how well does it work?

Wow!
Think you’ll need this Keith?
I can grow up enough yeast for a 3 bbl batch in 5 gallons of wort. Would save me a ton of money.
Thought this would be the case. Bit of overkill for the majority of homebrewers. I would snap it up at that price too.
Wow, I have often considered How Id get my yeast for a 3bbl brewpub I plan on opening. Looks like that may be the answer. Thats gota be a huge savings as opposed to outsourcing a proper pitch for 3 bbl. Great find, I say go for it! Worst case scenario youre out 150 bucks.
got to have the right kind of container–website says you can’t use the plastic fermentation carboys. So, what can you use?
Glass carboys work it says. Just a standard 6 gallon glass carboy?
I have flat bottom glass carboys. I can also get it for $125 through foxx equipment, $119.19 for 6+ if anyone is interested in a group buy. 
According to mrmalty you’d need 3876 billion cells of yeast to pitch into 1.060 wort.
What do you reckon you’d have to do to get the appropriate amount of yeast?
Id actually be interested…seriously lol.
MrMalty says I would need 10 vials for a 1.050 beer and 4.25 gallons of starter. I would probably order a 1 bbl pitch and add a portion of it to the starter. Not sure how much yet, I’d need to do some calculations.
According to Beersmith 2.0 a 3 step starter with 1 pack will give you @4200 billion cells
step 1: 1 pack (96 billion) in 1l =397 Billion
step 2: 397 Billion in 4l=1588 Billion
step 3:1588 Billion in 4l=4290 Billion
Shoot some pure O2 in the starter every 4 hours and you will probably get more.
Tom?
If thats the case and you can do up to a 5 gallon starter(approx 19L) you could step the 4 L starter up to say a 8 or 9L starter and have enough no?
I don’t use Beersmith, but that seems incredibly optimistic, both in comparison to Jamil’s calculator and other things I’ve read.
There is a reason, which escapes me, but the most growth you can get, per step, is about 4X. So you could eliminate the first step by throwing 4 vials into 4L, but why?
I think you can get something cheaper through a lab surplus outlet. I got an old heated stir plate for $50 online a few years ago. The nice thing is you can boil on it while stirring.
That’s how I got both of my stir plates (they are heated too) but I doubt they would work on a 5 gallon carboy.
In my case, I’m willing just to spend the money rather that hunt around on some site for days or weeks.
Fair enough, you have your priorities. Mine will stir a carboy though, if you use a good enough magnet on the inside.
Starters aside, am I wrong that if you were to use this for “dry hopping” as the flyer suggests you’d end up with an oxidized mess?
No O2 means no oxidation, so you’d have to make sure it was purged well. I wouldn’t bother for dry hopping them.
