King Oyster / King Trumpet Mushroom (Pleurotus eryngii)

Oyster mushrooms, members of the Pleurotus genus, are a group of gilled mushrooms prized for both their gourmet culinary applications as well as their "superfood" nutrient profile. There are around 40 unique types of oyster mushrooms, including Pleurotus ostreatus. The oyster mushroom is widespread in many temperate and subtropical forests throughout the world. Documented use of the oyster mushroom for medicinal and culinary use dates back to 2,000 years ago in parts of Asia. Due to its dense nutrient content, versatile flavor characteristics and its sheer abundance, it has been a main food staple in many cultures across the globe, even shaping history by providing thousands of people with nutrient-rich emergency sustenance in war-torn Europe. As we are constantly learning more about other species of mushrooms' roles in modern medicine, it is impossible to overlook the research being done with the oyster mushrooms as well. Among the observed health benefits of oyster mushrooms, some of the most promising relate to its ability to regulate cholesterol levels, its positive effects on cardiovascular and immune health and its high levels of naturally present compounds that may suppress certain cancers in humans.

*This syringe will come with a clear/white syringe cap, indicating that this mushroom species grows in hardwood substrate. This mushroom will thrive on our FOREST GOLD GROW BLOCK or FOREST GOLD HARDWOOD SUBSTRATE.

*Please note that our grow block is an all-in-one kit, (requiring only a live liquid mycelium culture), whereas our substrate will require you to create a separate colonized grain spawn first. For those unfamiliar with growing mushrooms at home, we highly recommend starting with our FOREST GOLD GROW BLOCK for the best chances at success with the least amount of products and effort. 

We have simplified the process of finding the right growing products for each strain of mushroom we sell. All live culture syringes will come with either a clear/white or black screw-on syringe tip cover:

  • Use BLACK GOLD GROW BLOCK or BLACK GOLD SUBSTRATE for all black-tipped syringes. All “BLACK GOLD” products are designed for compost and dung-loving mushroom varieties. “BLACK GOLD” products will come in black packaging and will be clearly labeled for use with black-tipped syringe specimens.
  • Use FOREST GOLD GROW BLOCK or FOREST GOLD HARDWOOD SUBSTRATE for all clear/white-tipped syringes. All “FOREST GOLD” products are designed for hardwood-loving mushroom varieties. “FOREST GOLD” products will come in white packaging and will be clearly labeled for use with clear/white-tipped syringe specimens.

Leave the guesswork behind and get the maximum benefits from your live syringes!

Perfect Pillow
Size: Queen (Pack of 1), Color: White
These are the best pillows ever. You can adjust the firmness or softness to whatever you want. For years i used a soft latex pillow , which you cant get anymore. I will never use another pillow. I have purchased 6 of these after the first one. You pick your own comfort level. Best ever. No more neck aches.

Hallelujah… finally, I found the right pillow!!!
Size: Queen (Pack of 1), Color: White
I have spent a lot of money searching for the right pillow. I recently tried to Tempur-pedic that cost twice with this pillow cost. Tempur-pedic flattened out. I’ve had this pill for a few weeks now and it works wonders. I am a paraplegic. You can have a lot of neck problems. I love the fact that this pillow is adjustable. I immediately saw it was too stuffy and took a bunch out. It works perfect so glad I didn’t spend money on a $200 purple pillow. I read a lot of reviews and there were a lot of complaints about the odor. Mine did smell funny when it came out of the box. I immediately threw it in the dryer with a few bounce fabric sheets came out smelling fine. Pillows are a very individual thing, but I think for 40 bucks this pillow is worth a try. I’m really enjoying mine about one of those silk pillowcases to go over it and it sleeps cool and comfortable. Best wishes in your search for the right pillow. Update: I’ve been using this pillow several months and it continues. Give me a good night rest pain-free.. well worth the money. UPDATE: I have been using this pillow for three months and it still works great. It does not flat out or get hot..

Soft comfortable very good pillow
Size: King (Pack of 1), Color: White
I really love my new pillow it's great and comfortable. Yes, it has a little smell, but if you wash the pillowcase and put the pillow on the window for a day you won't notice anything anymore.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes
