Abstract
PREMISE A CO 2 control system is important for investigating how elevated CO 2 affects plant growth. Our automatic CO 2 monitoring and control system offers an inexpensive and flexible way to make CO 2 ‐enriched environments. METHOD AND RESULTS Using microcontrollers paired with non‐dispersive infrared CO 2 sensors, relays, and valves, we developed a low‐cost system for monitoring and controlling CO 2 levels in growth chambers. CONCLUSIONS Compared with existing commercially available CO 2 control systems, Arduino‐based microcontrollers offer affordable access to the data logging of CO 2 levels in growth chambers, thereby reducing budget limitations for creating growth conditions with highly controlled CO 2 concentrations.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
