Growth Begins Within – Premium Tee
🌱 Built from the inside out. 🌱
The Growth Begins Within Tee is all about the mindset — steady progress, patience, and doing the work behind the scenes. Featuring a bold skeletal hand holding a mushroom under a radiant backdrop, this design hits with depth and intention while still keeping that clean Mycology Simplified style.
Printed on a premium, midweight tee, this one brings a little more structure than your lightweight shirts. It’s soft, durable, and holds its shape — perfect for everyday wear without feeling thin or flimsy. Whether you're working, out and about, or just keeping it low-key, this is one of those shirts that fits right into the rotation.
Clean Fit. Strong Fabric. Meaningful Design.
Shirt Details:
• 100% combed ring-spun cotton
• Midweight 5.5 oz fabric — soft with a durable feel
• Side-seamed construction for a consistent fit
• Drop shoulder sleeves for a relaxed look
• Reinforced 1 × 1 ribbed collar
• Tear-away tag for added comfort

These unicorn bags are the best in the market. We always get fast shipping and great customer support from M.S.! It's a great partnership between our two companies.
Very high-quality
Fast delivery
Works as intended, let it run in your space for about 24 hours. It needs that much time to get the right readings.

Perfect for the project im currently working with! Packing is top notch. The product has perfect moisture content on arrival and come double bagged to hold it all in. Im impressed and will continue to purchase from MycologySimplified for my grain and substrate needs.
The dishes that I ordered arrived as clean dishes ready to use. Very happy with my selection and after getting plates clean and usable i couldnt be happier. Thank you Mycosimplified.
Exactly as described, this company always comes through for me!
5 stars for the grain. Inoculated 3 days ago, already seeing growth. Haven't been able to try to substrate just yet. Few more weeks for that. Package was nice and secure. Everything nice and vacuum sealed in separate bags is awesome too!
