Good quality, quick delivery

I ordered a Lion's Mane Culture syringe and some Agar Plates. The ordering process was straightforward on their website. It shipped out pretty fast, took about 4 days to reach me here in Arizona. Everything was packaged really well, no damage. The culture itself looked clean under the microscope and has been colonizing well on the agar. I even reached out to support with a quick question about storage, and they got back to me the next day. Very helpful overall for a hobbyist like me.

Decent price, worth it

I was looking to try growing mushrooms for the first time and wanted to keep costs down. I signed up for their newsletter and got a 10% off code, which helped with my first order. I bought a Pink Oyster Culture and a small substrate mix. Shipping was free because my order was just over $100 after the discount. Everything arrived fine, and it felt like a good deal for what I got. I'll probably check them out again when I'm ready to expand.

Amazing cultures, super fast!

Got a Blue Oyster Culture syringe and a Sterilized Grain Bag, and I'm so happy! They arrived so fast, like three days, which was awesome. The culture is super healthy, already seeing mycelium spreading like crazy. I'm definitely buying all my supplies from them again. You should too!

Can you use more than one discount code on an order? Got a newsletter sign up one and saw some bulk deals.

E Emma 2 months ago
Nah, pretty sure it's one code per order. You can usually get free shipping if your order is big enough though, that's automatic.

Yeah, I tried to stack once and it didn't work. Had to pick the best discount for what I was buying.

Are their liquid cultures actually good quality? Heard some places sell contaminated stuff, don't want to waste my money.

N Nick Z. 2 months ago
I've ordered a few times and never had an issue. Always clean and vigorous growth for me.

Yeah, they're legit. I've had good luck with their stuff, way better than some other vendors I tried before.

Hey, wondering if anyone knows how long shipping usually takes for Liquid Fungi orders? I'm in California and want to get some stuff before a long weekend.

G Gwen H. 2 months ago
Mine took about a week to get to me in Arizona last time, so CA might be similar. They usually ship pretty quick though.

A Anna H. 2 months ago
Yeah, I'd say plan for 5-7 business days max. You'd probably be good for a long weekend if you order Monday or Tuesday.

Are these guys legit? I see a lot of different mushroom sites and it's hard to tell what's real and what's not.

C Chris 1 month ago
Totally legit. Ordered from them a bunch, cultures are always clean and viable. Family owned too.

Yep, they're a good one. I've had good experiences with their customer service too when I had a question about storing some grain spawn.

What's the shelf life on these liquid culture syringes? Trying to plan out my grows and don't want anything to go bad.

D Dana 2 months ago
If you store them in the fridge, they last for months, usually 6-12 months at least. I've used some that were even older.

Keep 'em cold and dark, they'll be good for a long time. I usually try to use them within 6 months just to be safe, but they're pretty robust.
