Awesome service and company 👌


Had a bad batch. He replaced it instantly. No questions asked. Tap in.


I am more than satisfied with SporeNSprout. I'm a huge fan of the products and the YouTube videos. Without this company I wouldn't be able to grow. Package came earlier than expected, cultures were completely sterile and free of contaminates. I would and have recommend shopping here to other people.



I reached out for something unrelated to my purchase. I asked a question in regard to what type of printer and program they used to label their products. The packaging, labeling, shipped as quickly as possible for live cultures in my opinion. All of my syringes were 100% clean, with no contaminants detected. I would recommend and I plan to order from them in the future.
