Monotubs monotubs monotubs
    #5595108 - 05/05/06 08:01 PM (8 years, 4 months ago)

Alright, i have a few different questions pertaining to procedure, with a monotub setup.

First, with regards to pastuerization, does anyone else here use ovenbags in a large pot of water, basically doing the pillowcase method, but adjusting the poo water content first, and doing it in oven bags? If so, does it take youa ridiculously long time to do? Is there any problem with having the water be at a higher temp. closer to 190-205 degrees while the poo itself actually starts to approach 160-170, and then turning it down?

My only worry is that i'm getting some of the poo too hot, and hurting it, but i don't know if i can handle letting poo take close to 4 1/2 hours to get to 170 in the middle by leaving the water at 180. Any help appreciated.


Next, concerning polyfil. I did a search, i looked. found nothing (in the forums). I just want to know how dense, or just how much polyfill should be stuffed into 1" monotub holes. I've never done anything with polyfil before, so i didn't know if there was such thing as too much, or too little in the holes. Is it fine its enough to stay fairly snug in the hole?

Next, In theory, coudn't you spawn to horsepoo, and then when that completely finishes colonizing, using that to spawn to even more horse poo, and then when that colonizes, using that to spawn to even MORE horsepoo.... etc. I have 20 colonized BRF jars, and i planned on doing a big 30 gallon monotub and a smaller 18 gallon monotub. Will 10 BRF half pints be enough to do a 30 gallon tub with 3-4 inches of substrate? If not, does anyone have any recommendations on what the best and fastest way to turn 10 BRF jars and excess poo, into enough substrate to 4" a 30 gallon monotub?

Oh, and one last last question i tried to find answers for... right after mixing my spawn and poo in my monotub to colonize, do I need to do anything specificially to hinder FAE while its colonizing, or anything to do with humidity? What i had in mind was, covering the substrate with plastic for 5-7 days, and then taking that off to put on casing layer, and then plasticing up the top of the monotub, this giving acces to the polyfill holes that would not have mattered to the previously plastic covered colonizing poo. any opinions?

Long post with lots of questions, thanks to anyone who can help.

Its only been an hour and a half...you shouldnt bump yet.

Anyway, lets answer your questions. I have used a monotub for three grows now. Good stuff!

Polyfill: Just stuff the holes. No magic number really. As long as it says in there without gaps, you should be ok. Do not make it dense though. Just put enough in there.

Pasteurization: I used the oven bag hot water method ever since I started and it worked fine. I was also skeptical about the INTERNAL temp. Didnt have any contams though, so whatever.

I would think that amount of jars would be fine for the amount of poo you are talking about. I always use grains though so I really dont know.

Colonization: I just get the tub set up, polyfill and all. Line it with poo, and put my spawn in. Then I just put the tub in a black bag. It colonizes fine. A bit slower (like 2 or 3 days) that I have seen smaller casings in an incuabtor, but it doesn't matter. Just a bag and you will be fine.

Well, just don't let your poo get over 180-290F...I forget what Agar calls it but it's when you're BOUND to get fermentation and n such :thumbdown:

Hope it all works out :thumbup:

its impossible to keep the entire pot of water at the same temp, i kept running into it where the bottom would boil but the top would be only about 170 so i started using my oven w/ a meat probe. it works great!
I boil the watter, cram the fully saturated straw in there and try not to scald myself too much, then stick it in the oven w/ the ovens temp probe in it. then when the internal temp gets to 175 the oven turns off.
usually takes about 2h after putting it in the oven. i don't see any reason it wouldn't work for poo. the trick is using the oven to only keep it at a certain temp and not try to heat w/ it cause air is so dam slow.

Well, you're suppose to get the water at a good 180F..THEN put your bag in...Cover and it should stay within the 150F-160F range...which has worked perfect for me so far :thumbup:

I've noticed that straw doesn't need to be pasturized nearly as long as poo...(like 45 mintues)...I'm assuming that this might be because it is less dense...I highly doubt that poo needs to be pasturized longer than an hour....

Only prob. I see is getting the core of the bag of poo to get to 170F-150F for a good hour...Which is probably why everyone pasturizes it for like 2-3 hours...

I bring all that up because i'm sure someone will say that the temp. of the water will increase greatly nearing the end of pasturizing...and my point was that you don't have to pasturize longer than the water can stay hot...Unless of course your house is like 50F...In which case i'm sure the water would get cooler way quicker.

As long as you aren't letting to much steam out of the bag, then i'm sure this would be a better way for those having problems with the pot.

why is it unnecessary to open a monotub to give it air  but very important to "fan" cakes in a rubbermaid often?

also once the cakes reach full colonization, i know they need to have a couple days to a week or so before birthing, should i keep the same enviromental conditions as when they are beggining to colonize?
THANKS

the polyfil holes let old/used air out the bottom set, and the fresh air comes in through the top set of holes,. it changes its own air,. is also helps to have a little fan in the room,.. not pointed right at the tubs though,.

and the reason you fan the other tubs so much,. is prob because its a tub set up without holes,.

also the monotub makes its own humidity where as some of the other tub styles dont do that as well,. so require misting and fanning for FAE

Hi, Im sorry for threadjacking, but why is pasteurising in pot of water preferable to pasteurising oven bags in an oven set at 75 degrees C (whatever that is in F).  Is it related to temps in the centre of the bag?  Or is it a 'My wife won't let me cook shit in the oven'.  If it's the latter I can totally relate...

for me,. it would be the ease of doing it in a put/bucket,.. and also,. it stays nice and moist,. where if you do it in the oven it dries it out some,.

maybe someone else will chime in

Because water conducts heat much better than air, so baking is very inefficient. It takes too long for the center to come to temp.

so its unnecessary to keep the casing moist in monotubs?

The idea is to get an evaporation rate that makes the moisture in the substrate last through the flush without having to mist.

But nothing is perfect. You could have the fill too loose or too tight or the air could be too dry there. You may need to fan it some if it looks wet or you may need to mist it once or twice during the flush if it looks dry.

I would def not mist prior to first flush unless it just looks super dry. There should be plenty of water in there. How long it lasts depends on how good you are attaining the right rh / rate of evaporation. 85% is about right on a monotub.
