  • Outstanding Customer Service
North Spore is one of the best companies that I've ever dealt with. I bought an automated bin and it was damaged during shipping. I contacted them and they responded within 30 minutes and sent me a new one. Outstanding customer service!

  • Amazing
I was very hesitant to try this but I'm glad I did. It has already increased my yield on syringes in less than a week. I debated on using the whole spore syringe but went for it to ensure I got enough into the jar. I'm very very pleased with the construction and ease of use with it. The jar is going to take my $15 ish dollar string and give me many uses instead of the normal 2 for just as much as an extra spore syringe. Way more cost effective and useful. ... show more

  • Read it !
Thinking it’s a company dedicated to cultivating I can’t imagine something like this would happen👎🏽I I bought 3 but one of them came not sterile, as shown in the picture it came with a black spot on the breathing pad/port, it’s my first attempt at cultivating and it smelled like mushroom or something similar to an earthy smell at the time I didn’t tink it was a problem so left it alone it’s been a month of growth and today I checked up on them to see how they are growing but one has something else growing. Ik it wasn’t my fault because the rest are fine they are in the same spot, did a sterile transfer from an injection at the same time I’m upset because it’s just a waste of money and now I have to buy a culture again and idk if I could trust this company again to keep a sterile work place for now im just going to throw it away the trash. Some of the positives, I would give it a 5 because the mycelium looks good and healthy it’s really grown and I really like how it comes with an extra silicone cap I thought it was small but when storing them you’ll find they are perfect it doesn’t take a lot of space I have mixed feelings for this I’m willing to give them another shot but I hope they read this review so they could be more considerate of there product or the people working there how could they missed a black spot and I’ve should’ve know but that’s how you learn. ... show more

  • Better off making your own
I was hopeful since this came from a well known supplier I’d get good results but that’s not the case. I inoculated with 5-6ml’s from a 10cc multispore syringe and haven’t seen any growth in 6+ weeks. The remaining 4 ml’s of my 10ml syringe went into an all in one grow bag and that’s well colonized with no issues so I know the spores weren’t the issue. I’ve since made my own LC and have an abundance of mycelium growing rapidly. ... show more
