EC920
- Good start value I think. Within the 800 - 1200 range for lettuce. It is staying consistent, as expected since germination should not be taking in any nutrients at all.
pH7.3
Very slightly alkaline. Not sure. If this is a cause for concern. Still lower than typical tap water pH7.7, so I guess that's good.
Another observation is leca balls at the top are drying out. Will leave it as it is for the time being.
