First timer

Technically second time, had an "all in one" bag substrate and grain. It was sh*t. So, next I tried the uncle Ben's method, awesome results. Filled 2 of these 5lb (one per rice bag) let it colonize a little more and now Im fruiting, so far everythings going great (knock on wood) 100% recommend

5 STARS

This product is definitely 5 stars!!! I've gotten this 50/50 mix a few times now. I've always had great results with it over the years. It's easy to use and works GREAT. Just add your substrate to the mix and within a week I always see rapid growth. My past results have been great! Looking forward to multiple flushes again this time! It's very easy to use for both beginners and pros. Once you try this stuff, you'll never waste your money anywhere else. Out-grow is simply the best.
