Let customers speak for us
from 49 reviewsVery impressed with the amount of mycelium in each vile of culture.
I dont often write reviews, but I am so impressed with the quality of these liquid cultures. I have worked with lc from many well regarded suppliers and these are easily my favorite. The density of the cultures is unlike anything I seen. They provide double the volume of a standard syring, but the amount of culture is at least 4x. No free space. The moment the mycelium hit the grain, it began tearing thru the substrate. I highly recommend Cap n Stem and appreciate the standards they are setting in our industry.
I love the millet. It is super clean, and your shipping methods with the insulated box are really great.
I have been a repeat purchaser for a while now and it's all quality. The price is great and the spawn is very fine allowing me to make so many blocks from one bag of G2 Spawn. Mountain View Mushrooms Certified!
Also they are basically my remote culture library allowing me to not have to worry about keeping up with lots of lab work and just focus on make the big bucks. Thank you guys for what you do. Hunter😁
Will order again to replenish my spawn
Everything arrived on time and in good condition
Culture came clean and ready to go and produced a consistent and high yield. Will buy again! Also they shipped all the way to Maryland with no issues.
Over 2.5 lbs of mushrooms on the first flush! Very tender & tasty!
Arrived promptly. Pinned nicely. I got a beautiful, hearty flush in only a week. I only with I could send a photograph of the flush.
