Excellent product and price
In less than 3 weeks I've seen tremendous mycelium development and no signs of contamination. Bags are VERY thick, the inoculation ports are super thick and self seal well. I did notice a huge amount of dulling on the syringe needle after a single puncture through the port. Like I said they are VERY thick. Be careful not to push too hard and puncture through the back of the bag. The small size and volume of the bags has allowed me to inoculate 5 bags using only 10mL of spores. The breathing port has a nice thick filter material, so follow the instructions included with the bags on how to introduce oxygen and prepare your grain bags before attempting inoculation. They arrived well sealed, with no visible humidity or moisture present on the inner bag surface, appears to contain the perfect amount of sterile internal moisture for quick mycelium development using only 2mL of injected spore solution. So far I'm very happy and have had very good results. A great tip, inoculate your grain bags when the moon is in the sign of scorpio using the sidereal zodiac system. You will be surprised how fast the mycelium will develop and establish itself.

Disappointing product
Grains come way to moist with many of the rye berries burst. One of the two bags I ordered on my second purchase from them had a wretched smell coming from it before I even had a chance to inoculate (noticed it when I opened the product and shook/“inflated” bag as per instructions before inoculating). My first order from them I purchased 6 BRF jars and 1 rye bag. I was happy with that order. The jars were as expected. No contamination and pleased with the results of shredding and spawning to coir. I was initially happy with the rye bag with the first order which is why decided to buy two more but that first bag has since stalled at about 95% colonized and is showing a ton of “myco piss” or yellow droplets up against bag. I suspect it’s fighting a bacterial infection so we’ll see what happens. I hadn’t grown mushrooms in many years and went with these due to the convenience of them. Only wish they had worked. Sadly I can not recommend these bags but I can recommend the BRF jars

PERFECTED !!!
1st things 1st! I’ve order 6 pounds 3X’S every single one of my bags were perfected! The mycelium came out with no problems at all!2nd! A lot of ppl who post bad reviews its only because they try to get into mushroom growing (mycology) learning based off of YouTube , tiktok etc. the whole www. Is cyber security, so when you post certain things they don’t want ppl to know , they red flag and take it down, so if there’s 3 steps to growing mushrooms they will take down 1 out of 3 of those videos . Leaving you to believe it’s not your fault.When it is, bc you relied of a controlled a.I. app mood director to guide you. Education cost , you will be charged in anything you do.With that being said when this product arrives you have to treat it with the upmost respect ! From how and where you store it . To temp. Control . Contamination awareness. If you don’t clean your home or work area thoroughly daily? You will contaminate this product without even trying ! This is bc your body is used to the bacteria’s you don’t disinfect, but the substrates and spores are not. Leaving you to think it’s the sellers fault !These bags are very reliable bc of the breathing port! Their very sturdy allowing mycelium to breath while keeping contaminates away(again) you still need to store in a control temp of 70 degrees sterile area.The injection port is very reliable and study !!! Their doing us a huge favor bc trying to sterilize the rueberry alone is a major job . Ventilation to the bag is another !I’ve bout 18 bags ! I highly recommend outgrow and this product !!!

2# bags
Its exactly what i ordered, I didnt read the size of the bags and just assumed this was a awesome deal on grain spawn. They are small 2# bags when the standard is 5#. I think they will be perfect for my 12qt monotub or double up on my 30qt
