What to log weekly
- Date and day of veg or flower
- Temperature and humidity, lights-on and lights-off
- Light height and dimmer setting
- Feed strength in ppm and pH, and runoff readings
- Watering volume and date
- Training or defoliation performed
- One wide photo and one close-up under white light
Photograph under white light
Photos taken under a pink or purple LED are useless for diagnosing color problems later. Turn on a phone flashlight or a white work light.
Review before the next run
Read the whole journal before you plant again. The pattern you could not see week to week is obvious across twelve weeks.
Frequently asked questions
- Is an app better than a notebook?
- Whichever one you will actually use. Consistency matters far more than format.
