Saw dust moisture content.
    #23878681 - 11/29/16 03:38 PM (7 years, 2 months ago)

I know this is pretty straight forward. Just want to run my thinking past some knowledgeable people who might see flaws.

So I'm trying to come up with a recipe for sawdust that I can use to cut down on waste. I've always just winged it so to speak with the moisture content buy hand checking it.

So here is my math. If I wanted to make a 5lb bag or 80oz bag that is 20% supplemented and lets say 60% water content.

Would this be a good break down?:

6.4oz supplement
48oz water (Weight not volume)
25.6oz wood pellets

I currently have a very small batch going.. waiting for the pellets to expand to see how the water content is.

Uh if you use 16 oz sawdust and 16 oz supplement then you have 50% supplement? Maybe I missed something.

That's why I'm asking. I've done everything by volume before.. Now im trying to switch over to weight.

Since water weighs the most out of all the ingredients it will make up the most weight.

Well if you want 32 oz of substrate multiply by .2 which equals 6.4 oz then 32 oz minus 6.4 oz equals 

25.6 oz of sawdust and 6.4 oz supplement your water is correct

Could do 66%, total dry weight + 2 x dry weight as water.

Substrate water guide:

x 1 Dry Substrate | 1 Part(s) | 50% Water.
x 2 Dry Substrate | 2 Part(s) | 66% Water.
x 3 Dry Substrate | 3 Part(s) | 75% Water.
x 4 Dry Substrate | 4 Part(s) | 80% Water.

Examples:

100g dry + 100g water = 50% water.
100g dry + 200g water = 66% water.
100g dry + 300g water = 75% water.
100g dry + 400g water = 80% water.

Or 1.4 x dry weight

For 60% moisture content you would want about 2 lb's of pellets and a little under half a pound of supplement for one 5 lb. bag. The rest water.
I think:confused:
It would be sweet to have a sawdust recipe thread, I have always just gone off of bigger recipes and scaled it down to what I was doing.

Well 1.4 x dry would be: 100g dry + 140g water. 140 / 240 = 0.583 * 100 = 58.4% water.

Son of a gun you beat me to it. I was in walmart with my girl and literally had a face palm duhh moment. My girl even looked at me and asked whats wrong.

I realized I was making the supplement 20% of the total weight and not the weight of sawdust needed.

I can't believe I did that.. lol

That is a really good idea. There isn't one already? Would be nice to have something to look back on. Would also be nice to have other peoples input on what is and isn't working.

Or 1.4 x dry weight




This is exactly how I was doing it before. I was using an old coffee can as a scoop. I was ending up with waste. My method was not refined in any way. This is an old habit I have from mixing plant soil. Not so easy to store left over  wet mushroom substrate.

You can't really do it that way. For example 200 ml (as a container) of verm would weigh nothing like 200ml of water.
200g of verm would equal 200g of water, hence the measure by weight and not container method.

Now for complexity, you need to know optimum water holding of the bran and sub.

For example the bran holds 66% water, the wood say only 50%.

So bran dry + 2 x as water, sub dry + 1 x as water.

That maths is terrible. I understand it, but many won't. My method is about 1000x easier.

To add to the confusion, pellets have 3-5% water content, so don't forget to factor that in too!

The dry substrate I would measure out with the coffee can. The water I would add in small quanities till I got the desired results by hand testing for field capacity.

Sorry about that ferather I should of been more clear.

I want to get away from this method.

Ah right, fair enough then katbusa. I thought that was a weird conclusion.
I measure holding capacity and then calculate my water.

Different woods can hold various amounts.

I disagree and also think that not only you,  but nearly all readers of this board will be able to understand it. Your method is inaccurate,  wasteful, and I find it rude that you keep foisting it upon people while insulting their abilities to learn a different way.

That maths is straight forward and easy to follow. Home mycologists should want to learn this method as it can be accurately scaled to make 1 bag or 500 with minimal waste and variation from batch to batch.

Well I have obviously offended you so sorry, but I still find this easier:


(Dry - water content) + X = total

Example:

(100g paper - 4% = 96g dry) + 384g water (80%)
(20g bran - 5% = 19g dry) + 38g water (66%)

Total water to add: 422g - (4 + 1)

To be honest I do not find what Ferather has said to be offensive in any way. Differing opinions is what makes forums great.

That's why I started this topic. I wanted other people to see what I'm doing. Point out the flaws and give me recommendations on how to improve.

Hmmm. I just use 3lb hardwood fuel pellets, 2 cups wheat bran, 2Tbs gypsum, and 10 cups of water. Guess I'm just ghetto like that. :jimmorrison:
