Walmart Springfield hygrometers
I recently purchased a cheapo walmart Springfield hygrometer for once of my spare 100ct overflow humi's, after reading some info on coolidor cheaper setups. The one I read recommended it, and for 6.99 I was like heck yeah. Well I use the $15 hygros sold here and ci, and have salt tested them to within 1% rh so they are accurate pretty much to my needs. So I got my springfield and salt tested it before placing in my humi, it read 50% in a 75% enviro! So I don't expect much from a cheapo $7 hygro, but I just wanted to let all other brothers know if they are using this hygrometer they would be wise to salt test it just to be sure you aren't over or under-humidifying your precious stash. Its simple to know my hygro reads 25% low and I need to add that much to know the true reading, but just a word of caution because I read several setups on coolidors that recommended these. I'm going to try to add some drill holes to the back plate to see if that improves the readings any this week and I'll post my results, but just don't rely on these with your expensive puros in my opinion. I've read pages saying these things work great, and pages saying they read low so check yours out if you use them. By the way, I use beads that are brand new so I pretty much know they are working good based on my expensive hygros reading dead on 69 with them.
