Watering cycle

you should use the volume needed to get the whole substrate wet each time you irrigate. half-ass watering will promote superficial roots, potential buidlup of minerals and dry pockets in unusualy spots (instead of drying from outside-in..) RH can spike after watering but should be short-lived. you don't pick the volume. what makes up the substrate and how long you wait between dictates the volume of water needed per pot when you irrigate. if consistent about this, you'll need a consistent amount of water you can plan around, but only in hindsight is this volume revealed. If you constitute the substrate the same way next cycle and keep same habits, it'll be a similar volume. in my experience, all the gimmicks people proclaim to work seem to be false or are very thin on evidence. Lots of assumptions out there that get reinforced ad nauseun despite a lack of any real evidence.
