I've had a mini hygrometer inside the tent in the branches of one plant to get another humidity reading. The AC Infinity humidity monitor was within 1% of the mini hygrometer. So I finally got around to adjusting the Inkbird humidity monitor, and now all the readings are within a percentage point of each other.
They are both drinking a half gallon of nutrient mix a day at 1.8 EC. Today they were fed slightly higher at 1.9 EC. I left my small bag of Mega Crop open for one day by accident and the nutrient balls in the mix had already started to clump together from the humidity in the air. When I finally resume growing after these two I'm interested in seeing how the new Mega Crop version looks and performs.
