Looking to confirm a watering technique. I’m trying to water by weight so I’m doing half the container volume with water/nutrients which usually gives me 10-15% runoff. My question lies in the percentage of weight change to indicate when best to water again.

I’m trying a model first with the following amounts:

3.5” container with “oven dry medium” = 90g, Container and medium at full saturation (one cup water)= 290g.

3.5” container holds 2 cups of water. 1cp water/nutrients = 10-15% run off.

I’m almost tempted to re saturate once medium starts to pull from container sides but fear this may be to dry! Any help would be appreciated! Thanks again
