Level up plant growth with our growth tech hub. This section organizes the core concepts behind stronger, healthier planted tanks—CO2 fundamentals and delivery options, practical fertilization strategies (macros/micros), and lighting essentials like PAR, spread, and photoperiod. You’ll also find frameworks for choosing between high-tech and low-tech approaches, plus propagation concepts (cuttings, runners, trimming) to keep layouts thriving over time. The goal here isn’t a step-by-step tutorial, but a clear map of what to learn next so you can match techniques to your tank size, plant selection, and maintenance time. Use this hub to understand the “why” behind dosing, gas, and light before diving into detailed guides and hands-on workflows elsewhere on the site.
