This product is fantastic and Outgrow as a company is also a great bunch of people. I got my "All In One" grow bag and had a contamination issue (Bacterial not a mold or fungus) Outgrow was very quick to respond to me emails and replaced the bag right away once they saw it was contaminated. Customer service with them is excellent and honest! I will be ordering from them until the wheels fall off! I was totally blown away in a very positive way by my whole experience even though some of it wasn't optimal, I learned something important about Straw/Rye Berries/Manure in a closed ecosystem and the problems that can arise from that. Finally I will add this. I had 2 golf ball sized pieces of Mycelium survive the contamination, because I'm not someone with rigid beliefs and I was shooting for a silver lining I rinsed off the Mycelium, Pasteurized the contaminated substrate @190 degrees (A little high but I was trying to kill bacteria) until it went from smelling like gross feet to a woody mushroom smell. I took a small aluminum pie dish (Palm sized), sterilized it and reintroduced the living mycelium to the substrate. Today I'm about 5 days away from fruiting. Granted it is a very small amount of what was originally in the bag but because it was a sealed secure ecosystem trouble shooting and trying something to salvage something from the contamination worked for me this time. I wouldn't have been able to salvage anything if this was a substandard product. These guys have a great option for people interested in mycology but who isn't an expert cultivator yet, and if something goes wrong that you as a customer had nothing to do with as far as contamination they would in theory replace your bag like they did mine. Thank you very much @Outgrow I am thankful to have a product like this available!

I have had four very successful grows using these bags. Colonization was quick in the right temp range. Once half colonized mixed up the bag and allowed it to colonize again. Once pins started to show I used plasti dip paint to block light to the substrate and poked some pinholes right above the substrate. Then ventilated and misted daily with very nice yields. Very easy and no contamination. I have tried several different methods to produce and this one was the least amount of hassle and performed better than expected. Of course you can use other TEK's to achieve the same thing but this is easy. It is well worth the money and when I need another batch of fungus I will purchase again!

** moved from 2 stars to 1 star.** This deserves explanation that pinpoints the bags as the problem. Purchased 3 bags two syringes (two strains) and made some killer homemade Agar (personal recipe) for petri jars (poly fill breather and silicon injection port) Order of events: In sterile environment (bleached room, hepa filtered for 2 days) also created a glove box. I used 21 gauge needles to ensure self healing ports closed (18 gauge that come with syringes are too big in my opinion. A. inoculated two Out-Grow bags flame sterilized needle. (alcohol on injection ports) B. Using same needle and spores inoculated 6 separate petri jars C. Using second spore syringe and needle, again inoculated Out-Grow bag first. D. Using same sport syringe, inoculated 6 of its own petri jars E. Inoculated homemade popcorn spawn jars (silicon and poly-fill tek) prone to contamination I know, but this is one sterile environment... Proving very successful I might add. *** In short, two bags showing major contamination and stunted growth (different strains) despite being in same environment as all other homemade spawning jars which have zero contamination (albeit some have stalled). I inoculated the bags first because I thought they were the sure thing. It seems my homemade tek is significantly better and WAY LESS EXPENSIVE after fixed costs recovered. ** One bag did perform nicely and is still colonizing well hence the two stars not one ** I get that making substrate in bulk and transporting them must have increased contamination challenges. Granted I am newer to this hobby, but I think my controls speak for themselves. I have taken petri Jars and done mycelium transfers to homemade substrate jars and also don't have any sign of contamination yet either. All in the same environments as the Out-Grow bags. Sorry Out-Grow, this highly suggests your bags have a contamination defect (maybe filter or self healing port doesn't self heal). Only about 75 fresh grams of mushroom. I will grant that they were HIGH potency of nutritional value, but not much in the way of yield.
