Description
Day 6 into the MediMac reveg and the biggest lesson this week is one word: movement. Without air moving through the room, a sealed indoor space slowly kills what's inside it — that's how yesterday's early powdery mildew showed up. In this video I walk through why airflow, light, and movement are the three keys that keep a reveg healthy, and I show how the buds on the MediMac are visibly opening up and going airy as her hormones shift from flower back to vegetative growth.
I also pop into the hang-dry room to check on the moisture adjustment I made earlier this week — the room is slightly softer and crispier now than it was before, and a full curing walkthrough video is coming out this weekend to show the changes in detail.
What You'll Learn:
• Why airflow is the single most important factor in a sealed grow room
• Visual signs that a revegging cannabis plant is successfully shifting hormones
• How buds change shape when a plant reverts from flower to veg
• The connection between movement, light, and healthy growth
• How a small moisture adjustment changes a hang-dry room
• Why "3 to Thrive" — air, light, movement — is the baseline for any reveg
