All blue on the #chameleon sensor this morning in the onion patch. Had some decent rain last week (41mm) so the soil is still wet down to 60cm.

The chameleon sensor measures how hard it is for the plant to pull water out of the soil using four sensors buried at 15,30,45 and 60cm and shows either blue, green or red light depending on the reading. Aim of the game is to get blue, blue, green, red.
I usually post my #gardenspam at @foodgrowergram if you're interested. #chameleonsensor #measuringh2o
