Bulk spawn efficiency?
#22042563 - 08/04/15 03:08 PM (8 years, 5 months ago) |

I was wondering if it is more efficient to spawn more jars to a larger amount of bulk (like with a monotub), or to spawn fewer jars to less spawn (like a tray in a GH)? Has anyone performed this experiment? Do you think that the yield would be drastically different if I spawned 6 jars of colonized wbs to one mono, or spawned those same six jars to 3 smaller bulk trays in a mini GH? Assume that the amount of bulk substrate used was equal.

Using less spawn while only make the tub or tray take longer to fully colonize. Try to aim for a 1:2 spawn/bulk ratio or less.

you'll get more return from a tub by using more qt jars  not sure why you say stuff like that when you also have a thread called my first monotub? 
IME you get more total harvest from having two tubs with 4qts in each instead of one tub with 8 qts spawn. same amount of spawn and sub in total.

Say stuff like what? I don't get it.. Using more spawn per same amount of bulk substrate means faster colonization times.

it will also lower yields.
and i'm not really convinced it makes that much difference in colonization times.
what I was wondering is how you can say stuff like this if you're just doing your first tub?

My first mono, but not my first bulk grow. I've done 2 successful 6 qt dub tubs and one 16 qt dub tub. And I've used different spawn:bulk ratios for each grow.

exactly, so you dont really have any reason to say one or the other way right. not trying to make a big deal out of it i just found the whole situation a bit odd..

I might not have dozens of grows under my belt, but from what I've noticed from my limited experience and what I hear from other TC's is that a 1:2 ratio or less is best to use, if you want fast colonization.

I never really use a 1:2 ratio anymore. I like 1:1.5 or even 1:1, of course the spawn jars are 2/3 full though.

i use 720ml jars for spawn
form one jar the average yield is around 30-40g dry spawn sub ratio is usually around 1/2 - 1/3
ur call really u wanna make small trays or one big one i find small trays to be more suitable for me,

Running smaller can give you more room to check out clones, isolates, do experimental grows, etc.

No, you misunderstand. The spawn ratios will remain the same for the trays and tub. There will just be three trays (or four or you would want to make them smaller) instead of 1 mono. Combined, the same amount of spawn and bulk will be used throughout the grows. Basically, I am asking if a higher biological efficiency can be achieved by splitting the same amount of substrate up into more containers.

Just because I have grown before doesn't mean I can't ask questions and continue to learn.

I say it's a valid question and maybe you should experiment and document it

yes, thats what I meant, you'll get more return if you spread things out IME.
that last part wasnt for you, of course you can ask anything you want

TL;DR
The old reccomended ratio was 10:1. It still is in commercial mushroom labs. You can yield just as much from 2 flushes at 10:1 as you can at 1:1. 1:1 will tend to be faster and put out more flushes because nutrients.
In the end though, when you think about myc getting weak and more prone to contams over multiple flushes, and most of us not having a real lab, 2:1 tends to be the most logical balance between speed and longevity.
If you have shit down and don't have to worry about contams, 10:1 is a great ratio. Grain prep is the hardest/most expensive/most time consuming part of everything. If you cut grain prep costs you cut your bottom line at the most essential part. It just takes a little longer, so your conditions need to be better than a spare bedroom for consistency.

the diff in colonizing times between 1:2 and 1:4 is a couple days tops, 2 tubs at 1:4 would outdo one tub at 1:2

  It doesn't matter what i think of you...all that matters is clean spawn I'm tired do me a favor

Really? What is your experience with 1/2 the normal spawn ratio? You don't think there would be reduced potency or reduced yield? What about senescence? Wouldn't a lower spawn ratio result in weaker mycelium overall? I'd definitely like to try it at some point, though.
