Great value on supplies

I picked up some Sterilized Grain Spawn and a few Agar Petri Dishes last month. The price was really good compared to other places I checked online. Everything arrived sterile and packaged securely. I used the grain spawn right away and it colonized perfectly. The agar dishes were also top-notch. I'll definitely be buying more lab supplies here for my next project. Really pleased with the quality and the quick delivery!

Mega Kit worked great

Got the Mega Mushroom Growing Kit a few weeks ago. Shipping was pretty quick, took 6 days to get to my place in Florida. I'm new to this, but the instructions were clear enough for me to follow. Everything grew just like they said it would. Happy with how it turned out.

Anyone know if their military discount can be used on the Mega Mushroom Kit? Or is that already considered a 'bundle' and excluded?

O Omar Reyes 3 months ago
I tried to use a coupon on a bundle once and it didn't work. Pretty sure most of their codes are for full-price stuff, not the already discounted kits.
5
R Raj Brooks 3 months ago
Yeah, I had the same issue with a different discount. They usually say in the fine print if it excludes bundles. Worth a try though, worst they can say is no.
