1. Be sure you individually mark each pot.
2. Write date on beginning of the notebook line.
3. I like to measure plants until they have been flowering for 2-3 weeks. Note height every few days for each plant.
4. Write down everything you do to a plant daily. Ex.- +12 oz. H2O w/ MG (miraclegro feed dissolved in the H2O).
5. Note physical features. Ex.- leaves curling, etc.
6. How close to the light is the plant?
