Just went out about an hour ago to check the containers for moisture content. We have had overcast skies and rain the last couple days. So I wanted to check on the drainage of the containers.

Moisture level gauge was mostly on high moist.
temperatures at 40 to 50 degrees at night and currently at 52 degrees this hour.
Light meter shows about 400 lumen's.

So with the temperature and sunlight lumen's I would consider the container drainage satisfactory. Could be my percentage formula for the perlite on bottom section of the wooden containers and vermiculite percentage on the top half looks satisfactory. The five gallon buckets with just vermiculite was in high moist.

At least the gauge did not jump up to the wet portion of the meter gauge.
