I'm a couple weeks away from harvesting (four varieties, which will probably mature at different times). Since you have a thread going on the topic, I'd like to mention a really excellent T/RH meter which I just purchased on Amazon. Don't have time at the moment to take pictures, but just search for the 'Tacklife HM01'. Strange name, good design. it's affordable ($20), but more than that it is ACCURATE and has an attached probe which can reach into jars or bags. Look at the picture and you will see what I mean. The only thing I can fault it for is that it always starts up in degrees C, so you may need to switch it into degrees F.
In my former life as an engineer, I designed a few instruments which needed to compensate for temperature and/or humidity. The best sensor element turns out to be from a company called 'Sensirion', and is identified as an 'SHTxxx' chip (xxx is specific version info). This meter is based on that chip, and it is very accurate and quick to respond. The other monitor I saw which uses this sensor is a wall-mounted unit: AcuRite 01083M priced at $15. If you wind up buying an instrument for this job, consider these two. Tried a cheaper one before and it simply was not accurate.
