SOPs

Welcome to the Grow Sensor SOPs library.

These checklists are designed to help you diagnose common grow problems fast, using a simple rule: measure first, then change one variable at a time.

Each SOP follows the same structure, so you always know what to do next and why.

Use them when something looks off, or as a weekly routine to catch issues early.

For best results, keep notes on what you measured and what you changed, and judge recovery by new growth, not old damage.
