A Note From BAM:
"This week, the plants grew. The controller failed. And I learned that sometimes the best tool in the tent is a grower who refuses to quit."

The Good: The Plants
The plants are now entering the final stretch of veg, and they’re doing exactly what they’re supposed to do. The FIM sites have turned into 4–6 main tops per plant. The canopy is widening every day, and the roots are filling the buckets.
· Plant 1 (Leader): PPM 628, pH 6.0, width ~50 cm.
· Plant 2 (Comeback): PPM 603, pH 6.19, width ~40 cm.
Plant 2 is catching up fast. The top feeder ring is now on full-time, and the difference in growth is shrinking. Both plants are drinking 3–5 cm per day.
The roots? Thick, white, and moving fast. I pulled them out for a video—they’re about 45 cm long. The song "It's All About the Money" played in the background, but anyone who watched knows: it's all about the roots.

The Bad: The AC Infinity Controller 69 Pro
If you're thinking about buying this controller: don't. Not for DWC. Not for a tent where airflow is critical.
This week, the controller developed new failure modes:
· It ignores manual mode. You set it to Level 4. It drops to 0.
· It ignores its own minimum speed setting. You set the minimum speed to 3. It sends an OFF command anyway.
· It jumps to MAX speed (Level 8) without warning, drying out the tent in minutes.
· It gets stuck in "Advance Automation" mode with no way to exit, rendering all controls disabled.
This is not user error. This is a defective piece of hardware.
I have an open warranty ticket with AC Infinity. They have not responded with a lot of communication. I am now running the fan at a fixed manual speed on a separate control setup, because the controller cannot be trusted with my plants' safety.

Closing Thought for Week 3
"The plants forgave the controller's glitches. The roots kept growing. The canopy kept spreading. And I learned that the best automation tool in the tent is not a chip — it's a grower who pays attention."

From BAM:
"AC Infinity, if you're reading this: your controller is broken. Fix it or replace it. I'm not waiting forever."
