Mushroom Grow Bags, 6 Mil Mushroom Spawn Bags, Mushroom Grwoing Grain Bags for Mushrooms Substrate Cultivation, 5" X 4.7" X 19.7" Mushroom Bags Kit for Outdoor Indoor (20 Pack)

Price is great, product preforms well and received quickly

I don't think these are sterile out of the bag so I have been using my vacuum sealer and sterilizing myself. I don't think these are as thick as some others have been saying. I would have preferred to have a larger size width-wise and not so much height-wise as these are 20 x5 x 5 roughly.7/10 I would recommend it. I hope this review is helpful.

I have been thoroughly satisfied with this multi pack of BIHYM Mushroom Grow Bags ever since receiving them! They arrived promptly and professionally packaged - I don't have to worry about cross contamination with these! They are true to size and design, and function wonderfully at my mushroom cultivation station! This is an excellent value for high quality grow bags! I highly recommend these!

The absolute worst mushroom grow bags ever! I am so confused by the other positive reviews for this item. I will make a quick and easy to understand list of why they are so bad. 1) They are made of a cheap brittle plastic that can not withstand temperatures of a pressure cooker 2) The bag material is so cheap that if you fold it will develop creases, cracks and air leaks and that is WITHOUT pressure cooking. 3) Even after wrapping them in multiple layers of extra thick aluminum foil the plastic melts. and destroys the bag making them completely useless. 4) If you try putting them in a pressure cooker without wrapping in aluminum foil they will literally melt into a blob of plastic that you will spend hours scraping out of your pressure cooker. Note* I have tested many variety of bags and have only had 1 other brand that was this bad. The whole pack is going into the trash, These will cost you money, time, effort and frustration. Oh and I almost forgot to mention they also lie about the bag thickness. These are not 6mil or even close, I would say less than 3mil.

Very sturdy bags that hold up to sterilization just fine. The micro filters are well made and the bags seal well and hold their seal. Good deal for the price. We've got Shitake galore in our house.

These mushroom growing bags are absolutely perfect for my needs, and have performed phenomenally so far!!I have had absolutely no issues with the construction and design of these bags, and the filter is securely adhered to the side. These bags should be able to hold roughly 5 pounds of mushroom growing goodness, and have survived the sterilization process well! The number five plastic these are made out of seal, extremely well, and I haven’t had any issues mixing after I have sealed the bag.So, if you are wanting to get into growing gourmet mushrooms at home, or simply want to entertain a science project, I definitely recommend checking these thick quality bags out!

These bags are not sterile, but the micron filter is nice to have .

There's better bags, but not for this price.
