Found this under the bed and thought it could be useful for new growers.
Stuck it in the pot to see if it still works. it seems to work just fine. Though we will test it at different moisture levels to see if it can be trusted.
A lot of new growers buy the 3-1 soil test thing, problem is it sucks for pH, sucks at telling the light level, but the moisture meter is actually quite useful, if you know how to use it correctly.
This is not a 3 in 1 device, just a dedicated moisture meter.
Right now the soil is still pretty moist under the surface and the pot is heavy. The moisture meter confirms this with a high moisture reading. We will do further testing with it and see.
