First casing / bulk grow
#13041202 - 08/12/10 12:14 PM (14 years, 5 months ago) |

So I've got more than 2 dozen quart jars of WBS and a bunch of 3cup and 4cup glad-ware containers colonizing. First 6 or so were form multispore, and the rest were all done with an LC that came from the multispore I used for the first jars. The LCs are catching up and mostly they'll all be done around the same time.
I'll use this thread to post pics of the grow once its started, but I had some initial questions.
Basic Procedure: COIR I'm following Damion's coir tek for 2 monotubs and for any additional spawn I'll make mini mono-tubs with a scaled-down version of the tek as well. I intend to use his measurements and add some gypsum in as well, no coffee though.
STRAW I'm going to follow shroomGod's straw tek for this one since its easy enough to do. The only change I'm going to make is the addition of gypsum. I'm not actually going to add it to the straw, just the water during boil.
Questions: 1. This one's been bugging me and I can't seem to find it on here. I know when you do cakes you are supposed to give the mycelium another week to get it all nice and strong, but is this necessary when spawning to bulk? I'm assuming not, since each grain will be an inoculation point of sorts for the bulk substrate.
2. Will adding gypsum to the water actually add anything to the straw? Or is this a waste of time?
3. Should coffee be incorporated? I've heard its more prone to contams, but if sterile procedures can fix that problem then its no biggy. Either way, I'll prolly throw some in one of the mini-monos.
4. Is polyfill necessary for the monos? My one container is 5 sq ft so way too much for shotgun style. I've read some conflicting views regarding polyfill, some saying its outdated. So I'm hopeing for some clarification.
Thanks and I'll keep this thread updated with pictures once the grow starts.

1) not necessary. Spawn when jars get to 100%.
...
4) I think it's detrimental, I believe you get better results doing it shotgun-style.

I'll wait for more input, but I guess I better start drilling holes soon... feck.

I will go against the doc for once here and say that you should use polyfil or a coolmist with a tub that big. I made a few very large shotgun/mono hybrid tubs and I could not keep the substrate from drying out. The ones that are smaller work real well but the big ones did not, even with persistent misting. Maybe doc can chime in with more help on this matter, but that was my experience.

I think the regular monotub polyfill works fine. It's been true and proven for years. And nothing a little fanning can't solve.
But, I am going to be trying out a mono-shotgun hybrid on my next tub, in a week or two.
I finally said fuck cakes completely. I'm gonna take the shotgun terrariums I have now and simply convert them 
I would think the shotguns would be more prone to contaminants due to more holes without filtration.. but it's not like it's a huge problem when your doing PF cakes -- I would think this would only matter in more moldy environments, towards the later flushes.
All speculation.

Beyond a certain size, you'd need artificial humidity in some climates, no doubt. I probably would here. So if that's a factor, then go with the polyfil. But, understand that the poly saves your humidity by restricting FAE. It's a tradeoff.

So if I use this giant ass container I've got (it was originally for a hydro grow that I abandoned) then I should hook it up directly to a cool mist?
I can use polyfill + cool mist if necessary. Or maybe make a hybrid, with small 1/8 inch holes just near the bottom so that CO2 can escape, with larger polyfill filled holes at the top and at the bottom. Then the cool mist can just be hooked up to the top area....
OR, excessive fanning and misting if I go with polyfill?

How huge is it? I'm not a big fan of big grows anyways, I think there's a lot of risk. With several smaller tubs, you spread the risk out. So I'm not especially knowledgeable on big tubs.

This is very true Doc, so funny I never looked at it that way.
As for shotgun hybrids drying out... it must be nice to live in a climate that dry!
I could set my shotgun terrarium outside without perlite in it, and I bet my cubes would grow famously. Wisconsin, living next to the river.. take a twenty minute walk and come back soaked.

how big is this tub, exactly?
i'd suggest a classic polyfil monotub. they seem to work great for any size (obviously with differences). The restricted air flow that comes with polyfil can easily be offset by fanning and misting.

Well the humidity is going to start dropping about the time when my fruiting chambers will be built, so I'm looking at approx 20-40% rh in the room. 40% being the indoor humidity on rainy days.
As my first post said, I'm going to be doing a number of small grows as well, but I wanted to maximize my possible yield for this one chamber. Everything else will be much smaller than this one and shotgun style will probably be just fine.

I don't remember the gallons, but its 5 square feet of floor space and its average height for the monotubs you see on this site.
Also, I the tek calls for casing, so I'll be spawning to straw soaked with gypsum water and then casing with 50/50 coir/verm with added gypsum.
Since I'm casing, will humidity control be as much of an issue?

And/or loosening the poly. They are really versatile if done right.
@Issius: Coir isn't really a casing material, it's more of a bulk substrate. It'll fruit- but you ideally want peat/verm instead.

Peat/verm it is then. I'm not really too hung up on the casing material.
