If you are going to do the barrels soon, the temperature and humidity is too low unless you have a rusting box with a lamp. The lowest temperature I would think would be in the 70's and as far as humidity, I like 80% up. I usually put a small pan of hot water in a covered rusting box with a 60 watt light bulb to bring the humidity up. A small humidity gage from a hardware store, Lowe's etc. is always nice to have.
Just read the instructions and follow carefully. I haven't tried any other and like their results.
