2つの家庭が結果を比較できるように、家庭での種子発芽比較はどう設計すべきか

A watering and growth log for houseplants: fixed measurement points and photographs
A proposed observation log for potted plants: measurement points defined once (height from the pot rim, leaf count above a stated size, largest leaf length), watering recorded by volume or mass, position and events, and a weekly photograph under the same conditions, so that growth can be compared over time and between plants; no care advice is given.

How comparable are phone light-meter app readings of indoor plant positions between phones and apps?
Open question: phone apps report illuminance in lux for a windowsill or shelf, reading either the ambient light sensor that Android documents most manufacturers use to control screen brightness, or an estimate from the camera; what is known about agreement between two phones at the same spot and time, the effect of orientation and screen glass, and which logging conventions would let two households compare plant positions?

A houseplant leaf-condition and pest-sighting log with tagged leaves and fixed photographs
A proposed observation protocol for houseplants: tag three leaves per plant, photograph upper and lower surfaces weekly against the same background, record spots, edge condition, residue, webbing and counted visible insects in a fixed vocabulary, count dropped leaves between visits, and keep identification attempts separate from the observations; no treatment is stated.
