I’ve been scammed. I ordered a Cannatrol several months ago and never received it. Their distributor hasn’t replied to me for several weeks.

Hi, please send us an email at [email protected] so we can help, we are unaware of the details surrounding this and would love to learn more and help resolve this issue
When the monitor works it's magic. However, I keep having issues with the monitor. Cannot get off the "press screen for calibration" screen no matter what I do. I used to be able to get to the calibration screen after plugging and unplugging the thing over and over but this last time I cannot get the screen to do anything. I have had this unit about 6 months and this issue has persisted from day one. When I ask for technical help I get, " unplug it and plug it back in and calibrate it. This thing is way too expensive to have this cheap monitor on it. New monitor was sent, once installed the until performs perfectly.

I am a 1st time grower. My 1st harvest was in June and I'm sure you are aware of the temp and humidity requirements after harvest. Since I didn't want to run risk of bud rot, I opted for the Cannatrol. A friend harvested his plants back in February or March. Same strain, the smoke was vastly different. Both smoked just fine but the Cannatrol weed was smoother and more of a mature smoke. My 1st grow 2 plants 5.5 ozs. I can't say enough good things about this machine. It cuts your dry and cure times to 8 days vs a month. I bought this machine because I plan on smoking weed until I die. This saves me time and aggravation of the last 2 phases of my grow. Those precious phases will determine your weed quality

I got lucky. I got some side work and that side work bought me a Cannatrol! I've been trying to save for 1.5years but life gets in the way, but I finally have one. Here's some pros and cons I've experienced with this unit. Pros The Cannatrol really does the heavy lifting when it comes to drying and curing. I used to dry and cure for 2 months before I would sample my buds, with the Cannatrol it took 3 weeks to get to the same quality. The flower was smokeable after just 8 days...8 DAYS!!!! Another 10 days and it's absolutely 🔥🔥. I did experience the "lack of smell" on the buds, but upon grinding, the flowers smells just fill the room. I'm sold on the "casing" layer that it creates to lock in the terpenes. I've been growing and smoking for a while but this smoke is just different. There's something to the science for sure. (I saw the video with Mr. Grow it, so I popped some Acapulco Gold Auto seeds into a window planter. I wanna see how good the Acapulco Gold comes out. Will it be a home favorite too? ,🤔) I threw in a Govee hygrometer and just wow. The Cannatrol really does operate on a TIGHT margin. It took only 6 hours to get inline after loading it with 1.1lb of wet trimmed flower. The Cannatrol really is the little giant! Cons The price is high for such a small unit. It could have been a tad bit bigger. I can only fit a plant of 2 at a time to run a dry and cure cycle. I can only grow 4 plants max in my space and I would need 2 units to comfortably fit 4 plants. It's small. And I grow for personal use. Secondly, I keep the unit in my lung room because the climate is steady there. I really wish there was a function to turn off the display. I don't close my grow tents because I record time lapse video. The display is really bright. I have to cover the screen because I worry about the photo periods. Last is the drip tray. Super inconvenient having to pull the whole unit out to empty out the drip tray. My laminate floors already don't like me and have scuff marks from the constant moving back and forth. Especially when I put a pound of wet bud in there, I had to empty the tray 3x a day. Overall, if you have the money for it, I HIGHLY recommend the Cannatrol. I can grow conveyor style now and not have to worry about less then optimal environment levels for all stages of growth. Perfect growth, perfect dry, perfect cure, Happy Me! Thanks Cannatrol. I'll be getting a custom cover in the near future 😉
