Out-Grow's 50/50 Mix

50% of our great horse manure based mushroom substrate and 50% golden wheat straw

Mushroom Substrate

This is the perfect mix of our compost and wheat straw. This mushroom substrate will produce great results for dung/straw loving fungi species. You will get much larger yields using this 50/50 mix compared to just casing grains or all-in-one grow bags. This product is sterilized and ready to use at your front door. Simply add your gourmet mushroom spawn to the 50/50 grow bag, reseal it, and mix. Out-Grow's straw/compost mix is one of the best mushroom growing substrates available on the internet. We use only natural and chemical free products to make our substrates.

Out-Grow uses field leached and shredded horse manure, shredded golden wheat straw, coconut coir, vermiculite and a couple other secret ingredients to produce a high quality mushroom substrate with a very nice, airy texture. Out-Grow's 50/50 mix will come heat sealed and sterilized in a mushroom grow bag for your convenience. You can grow right in the bag or add to trays or tubs to grow in.

I spawned 1 pint to 1lb of Out-Grow's 50/50 Manure/Straw Substrate. 1 week later, it was colonized. I didn't have everything setup yet, so the casing felt a little dry. I dunked the entire casing before first flush. Today, I'm in the middle of flush 5 and that was the only time I dunked. Performs fantastically! I will definitely use this product again! A+

I've been buying this bulk substrate for more than 2 years now and not once have I ever gotten a contamination. You can't go wrong buying from these guys.

This is the fasted colonizing substrate ive seen from a bulk transfer and i used brown rice flour spawn 1: 2 as a experiment! Fast shipping and great prices! Outgrow manure 50/50 substrate is top notch! The prices are very low for such a qauilty product, and for that this site is the only site using for my growing needs! And believe me ive shopped around!

Quickly (2 days) received my 1 lb bag of 50/50 to check the quality. 5 days in and colonizing quickly! Definitely worth it. Novice mycologists can grow close to professional grade fungus. Bravo OutGrow! Thanks

this stuff really is the bees knees. i had given up hope on my jars that were colonized and coming along very slowly. so i was fed up and i decided to mix my grains with a one of these bags just for shits n gigs and to my suprise i started getting fast colonization all over my 50 50 mix. great great stuff

Was having problems with contamination when I tried to make my own substrate. This stuff worked great. Colonized quickly and my mushrooms loved it! Thanks!

First of all; Out-Grow and Mike are the nicest people to deal with. Now, the 50/50 Manure Straw compost is fantastic !!! It colonized super quick using colonized rye jars. And it produces some large gourmet mushrooms using the Out-Grow casing soil. I can\'t imagine any better substrate. I\'ll always do my business with Out-Grow. Keep on being the best and thanks for everything. :-) ~~~PEACE & LOVE~~~
