What’s Your Ceiling Height? Choosing the Right Strain for Your Space 🌱

Ceiling height. Every grower needs to know it. Every strain grows to it. Every light recipe controls it.

Here's how to match your strain, your light, and your vision to the ceiling height that fits your space.

**The 3 Strain Structures:** 🌱 **Indica** — short and stocky, tight internode spacing 🌱 **Sativa** — tall and stretchy, wide internode spacing 🌱 **Hybrid** — variable, depends on the cross

**The Light Recipe Rule:** 🔴 **Far Red** = pulls your plants TALLER (more stretch) 🔵 **Blue Light** = keeps internode spacing TIGHTER (shorter, denser) ⚪ **Full Spectrum** = balanced growth

**What's in this video:** — The "Ceiling Height" concept explained — Matching your strain to your grow space — Why light recipes control your plant height — How I learned this growing under trees at different heights — Cal-Mag + Medi-One recovery update — Applying "ceiling height" thinking to life goals too

Grow to your ceiling. Then raise it.

**What's YOUR ceiling height — in your grow AND your life?** Drop it below 👇
