We rebuilt our VIVOSUN grow tent after harvest with a fresh 50/50 living soil mix, upgraded lighting, and improved airflow for winter conditions. This reset creates a clean, stable environment that gives our Ed Rosenthal Super OG clones the healthiest possible start.
Upgrading our tent with the Vivosun LumaLight system—400W, 200W, and full side lighting—immediately transformed plant structure, canopy coverage, and overall vigor. This blog breaks down why balanced spectrum, even distribution, and proper light geometry matter so much for indoor cannabis performance.
Smart environmental control is the key to stable VPD, consistent growth, and stress-free cannabis cultivation. Upgrading to a smart controller allowed us to fine-tune temperature, humidity, and airflow so the environment finally works for the plants instead of against them.
