I Cut an Alocasia Corm in Half & Tested Every Substrate

Hi Pablo from Aroid Vibes Here! I cut my corms in half to see if I could get 2 plants out of them and test which substrate works best with my conditions! The results were VERY unexpected! If you haven't seen my Corms 101 video yet, watch that first for the basics, then come back here for the deep dive:    • Alocasia Corms in 2026: Everything I Wish ...   ⏱️ CHAPTERS 00:00 I Cut a Corm in Half! 00:38 What's Inside an Alocasia Corm (Cormel Anatomy) 02:00 ABA & GA: The Hormones That Wake a Corm Up 04:00 Does Peeling a Corm Actually Help? 04:45 The Experiment Setup & Variables 05:20 The Puddle Method Explained 06:40 Every Substrate Tested (Perlite, Sphagnum, Fluval, PON) 08:00 Prepping & Sanitizing the Corms 10:00 The Heating Mat Setup (80°F) 12:00 The First Corm to Sprout (Surprising Result) 15:00 Fluval Stratum Results 17:30 Perlite Results 20:00 Puddle Method Results 22:00 PON Results & Sliced Corm Update 24:30 The One Factor That Mattered Most: Temperature 27:00 Does Slicing a Corm Actually Work? 29:00 How to Sprout Corms Every Time (Final Tips) 32:00 Outro 🌱 WHAT'S COVERED How to sprout Alocasia corms, whether you can cut a corm in half to get two plants, the best substrate for corm propagation, how the puddle method works (and when to skip it), why a heating mat and root-zone temperature matter, and the biology of corm dormancy explained simply. 🪴 QUICK COMM CARE, if you're sprouting corms at home Keep them warm (a heat mat around 78 to 81°F made the biggest difference for me), keep them consistently moist but not drowning, and keep them in a closed container to hold humidity. Warmth plus stable moisture beat any single substrate in my test. 💬 Which substrate do you sprout your corms in, and would you ever cut one in half? Let me know in the comments.
