Great product! Great Company!
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!

And it really works!
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!

Hight contamination rate when compared to homemade tek. Proof provided
** 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.

Ordered two. First one didn't germinate anything. Second one going strong.
Product shipped quicker than I expected. The first bag I ordered never grew any oysters. A few days of inoculation I started noticing a reddish brown almost rust-looking deposit on the rye berries. Not sure if that was a bacterial growth, fungal contamination, or some kind of chemical reaction between the ingredients and the moisture, as I had ordered the bag during the height of the summer. But it's arguably my fault as I had waited a couple of days to inoculate the bag to begin with. I almost gave up on the whole growing oyster mushrooms adventure, but I read some of the competitor reviews and decided to give Out Grow one more try. When I got the second bag in the mail, I inoculated it the very same day. I first saw signs of life on day 3 but also started to see some brown slimey looking juice on the bottom of the bag, which had me worried. I patiently watched the bag and tried not to disturb it. The slime juice grew, but so did the white of the mycelium. The race was on. Eventually there was a solidly demarcated white colonization meeting the wet brown rye berries. I decided to take the risk and shake up the bag maybe a few days early, betting that the water is just condensation and contamination, hoping that I could just redistribute the moisture. But I wasn't sure how much to mix up the ingredients in the bag. The moisture did even out and so far the mycelial growth going strong, but I'm not sure if I should have shaken the bag until the straw and the manure were equally mixed with the rye berries? The bag still isn't fully colonized but it hasn't been more that four weeks yet. Does anyone know if I should shake things up further so more of the manure is mixed with the rye berries?

Smells different?
Not sure if it's hay/straw And if that's what puts off a different smell than I'm used to. Never used this brand or style I will rate once I see if it grows mycelium

Superior quality for premade all in one grow bag’s
Been using this product for several years now. It’s a great option when you don’t have time to do it yourself. I’ve never had an issue with the product but I believe that the vendor would do what’s necessary to maintain a good relationship should something go wrong on their end. I’ve had these blocks fruit for as long as four months in a shotgun fruiting chamber which any mixologist knows speaks volumes for the quality of this vendor’s products. And I usually get my orders really fast, it’s usually several days before Amazon predicts.
