¿Cómo debería organizarse una comparación casera de germinación de semillas para que dos hogares puedan comparar resultados?
Pregunta abierta: los laboratorios analizan semillas según las International Rules for Seed Testing de la ISTA, pero los hogares que comparan dos lotes de semillas o dos alféizares no comparten ningún protocolo; ¿qué tamaños de muestra, reglas de conteo, duraciones y registros de condiciones hacen que esas comparaciones caseras sean informativas y comparables entre hogares?

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.
