Ok I'm currently trying to rehome all my Bp's into my/there new rack which has heat tape running down the back it has 8 shelves enclosed all but the front it's open holds 41 quart bins. With that being said I asked my wife to order me a helix stat instead I got a hydrofarm which max's out at 108 I put the probe on the inside of the bin on the hot side best reading I got was an 85 then I taped the probe to the tape to make sure its works good it is! Left it taped to the heat tape, and put another probe in the bin called an acurite and its been holding at 84 by day and about 77 at night . Am I doing something wrong am I using poor quality?!? I'm wanting to order the Herpstat Intro now but before I do just wondering.....What to do?
