Hi there my friend!
I appreciate your past support and I am sorry to hear of issues with this product!
A search through my inbox shows me that you never emailed me with your issues or concerns- I'll shoot you an email after I submit this so we can get you another LM HT LC for free to replace the one you were having issues with.
I will say that LM in general can be difficult to work with at first while you get used to it. The mycelium of this species is very thin and whispy as it first colonizes plates/grain and substrate- and will eventually thicken up. Once you're familiar with it, you'll be able to spot the mycelium easier- it does grow quicker than expected. I have found that on agar it seems extra slow- the culture seems to grow in 3D more than other species and takes time to move across the plate as it eats into the plate (down) as much as it does across.
All that being said, if the culture was contaminated you would see contamination immediately and not only when fully colonized. This can indicate a small amount of contamination in the sample so I am happy to supply a replacement; but it can also indicate imcomplete sterilization or sterile technique so make sure you check everything before the next attempt. Blue oyster is insanely aggressive and would be able to outcomplete some contamination that LM would fall victim to.
But you shouldn't have any contamin in the cultures from me so lets get you a new sample to work with!
In the future, and for anyone else reading this review reply, I am happy to replace all gourmet cultures that have contamination issues as per my TOS. Just email me and let me know your problem and order number and I'll get you sorted out <3
Thanks for letitng me know of this issue so we could get you a new sample to work with and upgrade your next review for this product :)
