Placed Shiitake kit in my mini green house and took off in a matter of days. Took a little under 2 weeks to grow and tasted excellent.

I really like this product but I wish they had clearer instructions. Once the mushrooms start to grow they don’t tell you how long to leave it in the humidity bag. I did contact the company & they were very helpful and answered quickly. My grandchildren were excited when the mushrooms started to pop out. I do recommend and will be purchasing it again. ... show more

    • Grew some but not as many as I hope for
Style: Shiitake Mushroom Grow Kit - 2lb
The instructions provided were easy to follow. One nice big shiitake mushroom grew along with a couple of small one which stop growing in “Supercool” mushroom tent machine (keep good environment for mushroom to grow). Cut all mushrooms and tried for 2nd round. It was fun watching mushrooms growing and then so frustrating when they’re not obviously. Value for money? I bought shiitake mushrooms from stores because it didn’t grow as many I hoped for. ... show more

    • Good quality product
Style: Shiitake Mushroom Grow Kit - 2lb
Order two of these 1 pound shiitake mushrooms blocks. I was impressed with the way Oakland mushroom co. Package there product. This shiitake mushroom block is extremely healthy! Smells a bit different then other mushroom blocks, that is normal smell for shiitake. Got it delivered on the 9th of January didn’t start till the 11th Of January, I was harvesting mushrooms by January 24th. Instructions could be more informative, like the temperature for fruiting block. Grew one in the “kit”/bag that comes with this product. And one in a mono tub tek. I would 100% NOT use the bag that comes with the kit. Extremely difficult to keep the humidity bag up right without touching the shiitake block. The shiitake block in the humidity bag only produced about 4 mushrooms. The one that I grew in the mono tub tek grew about 8 ounces of mushrooms. Extremely happy with this product. Will recommend and purchase again. Pictures of the fruiting block are the first flush. The time laps video at the end is the second flush. ... show more

Followed instructions to every detail given. Not much to it. Fill bag with water, soak, drain, put in the other bag included and set in nice space to grow. Took almost 3 weeks to begin pinning, but mold began within a week at the base!! I removed most of what I could, to try and salvage , but still came back. Was not just surface growth, but throughout the entire block! (See last photo) Will reach out for replacement and see if I can get a 'clean' block. As for growing, 3 weeks later have a single mushroom growing. This looked to be a healthy block originally, and was hoping for good growth. Additional note: I do grow mushrooms at home, so im not a first timer with 'bought blocks' usually there's a decent chance of a contaminated block, but this was my first purchase from this supplier. ... show more
