what concentration of Honey or LME to use for LC
#27136881 - 01/09/21 06:14 AM (3 years, 1 month ago) |

What is a good concentration to use as a LC? I read that 4% was good, that is 4g of Honey or LME to 100g water.
But I have also seen that some people are suggesting 1g of honey/ LME to 100g water. In some cases I have even seen weaker concentrations.
(Please dont suggest that I try various concentrations to see which one works. It takes a fair bit of time to do these experiments. I just want to find a nice concentration that will work so that I can get on with growing rather than having to spend time figuring out what to do in order to be growing. Lets learn from each other and experts who have already been down the path. That is one of the reasons I am here...)
Many thanks good folks.

Run 4% if you want it to grow aggressively

I've had good success with pans at 1g LME to 500ml of water.

That's the ratio I use too (0,2%) and it's good for cubes as well. The broth will be very clear which is important and at that ratio there's more nutrition in the broth than the myc will use, some people go as low as 0.1% with great success. A colony needs very little energy to colonize an aqueous media.

This is what 0.2% LME looks like.

This is what a 50/50 dilution of rye grain soak water looks like.

The GSW may have been faster, but the LME is clear and easier to determine whether something may be amiss in mycelium town.

At the fraction of % ratios the growth in my LC is painfully slow.
Are you incubating the LC

0.2%... wow that is really low concentration.
I think I will try a few and see what happens. I will certainly give that low concentration a try.
I certainly want fast aggressive growth.
One of the issues I am facing is blue trich on the surface, so I have to chuck out the whole jar. Wasted time.

also what temp do you guys keep your LC at during inoculation phase?
I keep mine around 21-23 Deg C.

I run 2% honey. It is far more forgiving if you PC 20 minutes instead of 15...

Don't take me wrong I don't wanna sound like a dick, but it really doesn't sound like you have a good point of reference to say this. It is really not a low concentration, really more than enough.
This puts in perspective the 4% strength you were doing. Twice as much nutrition than a standard agar recipe and 20 times more than what you need for an LC, that's out of the charts nuts and does nothing but cloud the hell out of the broth.
Also, honey becomes sugar after PC'ing, sugar based LC's are not recommended. LME or grain water are superior, which answers your concern below.

These are examples of LME LC's at 0,2%, fast aggressive growth and lots of mycelial mass:
 Following some simple tricks, they can be done in as little as 7 days from biopsy (see first link in my sig).

Room temp is fine, 21-23 is perfect.

Yep 1 gram lme to 600 ML for me. Nice & clear. I recently tried GWLC & upping my nutes. Going back to old faithfull

Room temp worked for me. Growth was fast enough. Broth was clear. At the moment I have no reason to consider more than 1g LME to 500ml.

I've had mine in a cold room ~50F and while they do grow it's way better at room temperature (72F).

Thanks.. No offence taken. I was using 4% as that is the concentration used in the Psilocybin Growing bible!!!
I am trying some at 1% and 2% honey to see if that works.
Will try some at 0.2% LME as well now while I am at it.
I mean, I did not pick 4% as a random number, I thought I had a reliable source of info for it.....

4% is what Blue Helix uses and he’s a legend with his LC work... its just about what works for you. I decided on using 1g LME to 500ml water because I read somewhere lower sugar helps reduce contamination. I don’t know how true that is, but I’ve stuck with it as it works perfectly.

at 4% I have had problems with visible Trich blue mould on the surface.
I'll give the 0.2% LME concentration a try and see if that is any better. I also have a load of jars sitting at 1-2% of Honey solution.
I assume that once the mycelium is growing the LC can be kept in a cool place for ages and ages, perhaps as long as a year?

Yea I think you'll like 0,2%.
A 100% colonized LC has quite a bit of shelf life at room temp. I've used 2+ month old LC's without issues. After that they start to deteriorate and lose vigor. But it isn't such a good idea to use old LC's because it's so easy to make a fresh one.

It prob depends on the culture a lot but ive used lcs that were around 8 months and a year old and had sat at room temp the whole time which was over 100f half the time.
They definitely weren’t as quick as when they were new but still worked.
Like he said though lc is so fast I’d just make a new one unless it was some super genetics that were gone except the old lc.
