The Doc does a monotub (Pics) (Final Update)
    #8004104 -

Hi everyone,
This is my first real grow other then a couple PF mistakes... I will be inoculating WBS then spawning to H-Poo in a monotub. I have 6 fully colonized wbs jars already.



These jars are Koh Samoi from one of the sponsors. But I must say, this strain is a fantastic colonizer, 1 week from multi spore syringe to the above pic. I followed Doc's WBS tek which worked out great. I wanted to know why he suggests only filling halfway with grain, so I filled 3 jars to the brim to see what would happen...




As you can see, much slower to colonize. Now my question is, I built my monotub with 7 quarts of spawn in mind, is it a good idea to go ahead and use the 6 fully colonized jars plus one of the slow ones or should I wait till it's finished? Will uncolonized grain contam when mixed with H-Poo or anything like that?

I have heard that WBS retains great moisture, and I have also heard RR say monotubs don't need to be cased... Every monotub I have seen has had a casing layer, but what is the point if wbs is going to hold moisture for me? Has anyone ever done a mono with no casing layer, how was it?

While were on the monotub, here is a pic.



I cracked is good while drilling my 1" holes.... I used some gorilla tape to fix it right up. This will be 4"-4.5" deep after its filled up, I can't wait. I plan on using 4 mil vinyl to make a cover for this thing, that and a bit of poly should seal her up good.

Thanks for looking everyone, questions, comments, and critique welcome.

Your bottom holes need to be BELOW your substrate on the so the Co2 can "fallout"

seven qts is too much for that size of tub man, honestly. 3-4 qts is enough for that size.

Aye, RR says they don't NEED to be cased, but they perform better if they are.

Yes your uncolonized grains will contam if you spawn with them.

Some verm, coir or staw would help out your substrate also.

I left my c(oir)&c(offee), Koh Samui mono tub uncased and I've gotten over 2.5 ounces over about two flushes already. I think you're mistaken assuming that the wbs will hold enough moisture to get rid of the casing layer itself though. The reason you would want to case it is to give it a suitable pinning surface, to have those beneficial pinning micro-organisms that they're always talking about (I'm thinkging 50/50+ here), and to hold extra moisture through the flushes to help yield more. Wbs alone just isn't going to do that for you, but I've seen it myself that uncased tubs can produce. That was C&C though mind you.

do you really mean below? they're supposed to be on the exact same level as the sub so it can spill off...if it was below, the sub would spill out :tongue:

Civ, every monotub I've seen has holes at substrate level, not below. please explain how that would work without the sub pouring out after hes spawned.

Civ: I have always seen the bottom holes at sub level, thats what I did. I don't want my sub to get all over the poly or spill out or anything. You really can't tell from the pic, but that is a 58 qt tub, quite big, about 19"x13". I was going to add a bit of gypsum to the sub as suggested in RR's videos, but I have some verm and access to straw so I could add some of that as well. as far as # of jars. I'm using the 1:4 ratio here so I can get a nice fast colonization time.

I have all the materials to do a 50/50+ so if you guys think casing will yield better then I will by all means.

Thanks everyone!

Co2 is forced upwards from colonized bulk substrates, you should mark off with a ruler six inches, measure off 1 and a half inches every inch or so and drill half inch holes all around, plug them when you decide you want more or less substrate and stuff the appropriate holes when finished.

I'll post a picture at some point in my life of the design, it works real nice for when I have to much or to less and want to do a mono tub for convenience

HybridprX: What do you use to close the holes now that you have like 10 of them? Duct tape? Doesn't that compromise the integrity of the tub, that plastic isn't too heavy duty? Thats a great idea though, lets get some pics up.

Yes, below the sub!  At the least level with it.  Your plastic liner will make sure you don't spill all over :smile:

But, my subs are 7 inches with an inch of caseing layer-  I am sure smaller subs wont notice the difference as much with the level of the holes.

That tub is average mono-tub size, its when your up in the 80 liter tubs that it gets fun :smile:

OH BTW- that does NOT mean you ONLY put holes under your sub-  you put them all over, but some need to be at sub level at the least, some sub-sub level for the best IMO.

Notice the 7 inch crack on this mono- will it colonize?.....



like the americas!

masking tape, duct tape- its all good :smile: and it breathes so if you go easy it works wonders.

I notice the tap on your tub due to you cracking it.  If you start with a REALLY small drill bit, then move up to larger size, its a bit easier.  Also, if you mist water onto the area your drilling it helps relieve the tention.

Civ: The water trick is great. It was weird that it cracked, I was using a hole saw, I've never cracked anything with that before.... I would have stepped up in size if I had used regular bits, but hole saws require some material in the mid to work right.

Maybe I will drill some small 1/4" holes below sub level, to try it out, good idea?

Right, because all the CO2 in the atmosphere "sinks" to the ground and suffocates us? :rofl:

Even if you had smaller holes at the bottom of your bin they would only be functional after colonization as the substrate retracts.

Looking good Dr, just remember 1:4 spawn ratio at minimum and you should be solid. Size of the tub looks good to me.

Case that bitch with 50/50 Limed to 8 and reap it.

Re: The Doc does a monotub (Pics) [Re: xeallos]

Here's a fun update for everyone:

I went ahead and started to pasteurize my H-poo/verm/gypsum mix. I filled about 5 quarts each into two oven bags. I lined the pot with jar lids to suspend it and everything. It went great until I went to pull the first bag out... I got it to about the pot lid level and as soon as I went to put my hand under it to support it, the bottom gave, showering my hand in 150 deg shit. Needless to say it hurt, made a huge fucking mess, and set me back a couple hours. On the plus side, the other 5qt bag is fine.

So now I need to do another bag/jars of pasteurization in order to continue. I rubber-banded the remaining bag quite well and have it cooling off. Will it be ok to wait about 12 hours before I pasteurize another batch? Will the pasteurized bag be fine?

I also realized I made a mistake in my calculations. In order to reach the predicted 4" depth, I will need to up my spawn to sub ratio to about 1:8. Would it be more prudent to change the ratio and level the sub with the holes? Or to have the holes 1/2"-1" above the substrate, making it about 3"-3.5" ?

Thanks for the help guys!

You guys are funny, its easy not to crack plastic tubs. You simply heat the drill bit (or what ever cutting instrument) over an open flame(I use the stove or my handy burnzomatic propane torch) for half a minute, maybe a little more, then drill. The Heat softens the plastic and allows you to make your way through with much less resistance. Use a razor blade to trim off any excess and your done.

Personally I would make it not as deep instead of adding more sub. If you increase the ratio it will take longer to colonize and the risk of contams goes up. If you did want to bulk up the sub a bit I would just pasteurize some straw by itself (soak for 2 hrs first or do a wet pasteurization) and add that to the poo. Straw will help airate the sub and speed up colonization a bit.

yes, on substrate/casing layer level.

Here are some pics of my second attempt at pasteurization.

I loaded 2.5qts verm/poo/gypsum mix into each bag. I double bagged the one that would hold the thermometer as I think the problem before was from a hole I poked in the bag. :blush:




I loaded them into a big pot lined with jar lids to keep the bags off the bottom. I pressed the air out of the bags and rubber-banded them closed. I used twist ties to suspend the necks to keep them out of the water.



I heated until the bags hit 150F and let them steep for 60 minutes.

"yes, on substrate/casing layer level. "

Your substrate wont fallout lol :smile:

OH - maybe you guys LITTERALY think I mean putting the holes on the BOTTOM of the sub/tub - that would be pretty shitty.

LOL . thats not what I meant- I meant to relay that you can place the holes , bottom holes, just slightly below the hight of the sub.



omg ohmatixckz!
hhhheeeaaaaattttbbbbbbooommmbbb! I still have one with the same water in it from 04!  sorry that was random.

I use wood drill bits also, they seem to be softer.

yeah, to make clear, I didn't be below your substrate, just an inch or so below the top of the sub.
