18 gallon monotub problems.
    #15907830 - 03/06/12 07:16 AM (12 years, 10 months ago)

Hi everyone im about to start my first bulk sub grow soon. I plan on using doc T's wbs tek to Damion's coir tek. Im going to use two 18 gallon  grey tubs. I want my sub depth to be around 4 inches. Im using 6 quarts of spawn for each tub with 3 quarts of fine verm., and one brick of coir for each tub. Now my two problems are:

1. where to I put the holes in my monotub. And how many. I don't know how  if my sub and spawn is going to reach 4 inches or not, so I don't really know where to put the holes.

2. Im not using a clear tub so in order to get light to the myc. when it is colonized can I cut part of the lids, and put a piece of plexi glass over it?

Thanks everyone.

Put the holes just above where you want your substrate. The theory is that CO2 is heavy, so it stays near the bottom. So we put our holes down there.

Plexi will work, since you only have two you could probably use just about anything translucent. Its not like your going to have to stack them.

I put my lower holes at 4" to 4.5".  If that's how much substrate you want, then adjust the amount of substrate and not height of the holes.  As for the number of holes, you can adjust polyfill to make up for having more or less holes than you need.  Just go with what you've probably seen in pictures here on the forums; that is, 2-3 holes on each longer side of the tub (at substrate level) and 1 hole towards the top on each shorter side.

You should put plexiglass on the lids before you even set the tubs up.  I don't know why you would think that you need to wait til after colonization, but having plexiglass taped to a hole on the lid is not going to harm or disturb your colonizing mycelium.  The only thing you can do wrong during colonization is introduce FAE prematurely, so don't go opening or cutting at the lid before your substrate is ready to fruit.

yeah I know I want to have to holes and lid correctly done before introducing the spawn the sub. Because I think doing it while it's in there would just increase risk of contamination. Im just trying to do some math and figure out how dam tall my total is going to be lol.

So what your saying is to put 3, lets say 1 1/2 inch holes on each of the long sides maybe 1 inch above substrate level. And one hole of the same size maybe 2 inches below the top on the short sides?

Use this to figure out how much bulk + spawn you need to get to the desired substrate thickness:

Then you can figure out where to drill your holes.

I am simply under the impression that 4in is way too much. Even RR says that 2 x 2in subs will give you better fruits than 1 x 4in sub. I would back it off to 3in, or even try doing 2 - 2in subs. just my 2 cents, but I have a 2.5 in sub going now and have been picking MONSTERS off of it.

Sorry that didnt really answer your question, but What I have done in the past is to dump your verm+coco+5-10 jars in 1 container, mix it all up and then scoop out the mix into another container until they are both at ~2in. That way you can get 2 monos going at once and have way more fun!

Also in that substrate calculator you showed me, when they refer to quarts of spawn. Are they talking about FULL quarts or 3/4 full quart jars. Because someone said in another thread that when refering to blank quarts of spawn a quart is considered a half or 3/4 full jar of spawn.

Your standard brick of coir (after hydration) is about 7 quarts.  Well, between 6-8, so yeah 7 quarts on average.

I, too, have heard that the latest consensus in the community is that 4" of substrate is too much.  If RR says it (which he did) then I'll believe it, but I've never done anything less than 4" so I can't comment.

OP, quit over-analyzing.  Just put some fucking holes in the tub and throw some spawn in there!

just did some math, 6 quarts of 3/4 full wbs is 4.5 full quarts, plus 3 quarts of fine verm and an estimated 7 quarts of coir, would be 3 1/4 inches of substrate level. so im gonna drill 3 1.5 inch holes on each of the long sides at around 4 1/4 inches. Is that good

I consider a 3/4 QT one QT for my purposes.  Whatever you decide, you will be fine. You will find spawn ratios range anywhere from 1:1 to 1:10 on this site.  I use a 1:4, but like The_Damn said, just drill some holes and spawn.

yeah im not trying to over think just wanna make sure I have everything down. I know its simple just alot of people tend to screw simple thing up. Should I place the holes at the substrate level or a little above (no more than an inch.) And nynole, I think everyone considers 3/4 of a quart a full quart, but I gotta use exact measurements for hole placement.

8 quarts of water and 8 quarts of coir have two different volumes. Coir can compress as you put it in. Just sayin

If you are casing, add in 1/4" or 1/2" or whatever you are casing with. You want the bottom of your holes exactly flush with the top of your casing layer.

Let your sub fully colinize before putting your hole in the tubs.  Your lids will not be air tight, so that will keep from getting the green.  When your ready to fruit, drill ur holes @ sub level 2.5" apart.  Then work ur way up putting holes every 2.5".  Do the same to ur lid.  Put under light 12/12 mist 1 or 2x a day unit pins, after the misting fan w/ the lid for a few seconds.  This is how I do all my tubs, w/ great success.

R we talking distance from the bottom of the tub to bottom of the hole or to the centerline of the hole?

Won't What?  Plastic Shavings?

Once ur sub in fully colinized, a little bit of plastic shaving won't hurt a bit.  At this point ur worst enemy would be pooling water.  But with all these holes will help keep it dry.  If ur having a problem keeping the humidity up, just tape up some of ur holes until you get it dialed in.
