Got my stacker today and the dang feet is far from where it should be....I should have just made it myself with wood...I think there might be two versions of this stacker which isnt made clear
I keep hearing different things about how the Cannatrol is supposed to behave, so I’m hoping some owners can share what they see on theirs.
The common advice is that with fresh, wet flower, the dew point should start high and trend down slowly toward 54. That’s not what happened on my first unit. With a full load of wet flower, it hit my target dew point within minutes, then overshot down to around 52.5, swung back up to about 56.2, and kept bouncing back and forth. The swings got smaller as it pulled more moisture out. Even with no flower and no sponge, it was still swinging about 1.3°F of dew point.
I placed my own sensors throughout the inside of the unit and noticed the temperature was uneven, with the top running warmer than the bottom. Cannatrol replaced the sensor, and after that the temp evened out across every shelf and the dew point held within about ±0.5°F, which matches what I’ve seen in reviews. Even with wet flower, it stayed close to 54. So it seems some units can look like they’re working fine when the sensor actually isn’t reading correctly.
That unit’s door was damaged in shipping, so I ended up getting a replacement. The new unit swings even worse. I had kept the old bad sensor, so I tried it in the new unit, and it behaved exactly like my first unit did before the sensor swap. Now another sensor is on the way.
When I told Davey my unit reaches target dew point right away and overshoots even with a full wet load, he was surprised, since it’s supposed to show high RH and come down slowly.
At this point I’ve gone through 3 sensors and 2 Cannatrols, I’m about to get a 4th sensor, and every sensor behaves differently. I can’t find anything published on what the normal tolerance should be, so I’d really appreciate hearing from other owners:
**1.** **Once fully settled** (just a sponge and dry bud), how much does your dew point swing up and down?
**2.** **With a full load of fresh, wet flower**, how does it behave? Does it start high and drift down slowly, or hit target fast and bounce around it?
Graphs or screenshots would be a huge help. Thanks!
