It has potential

This seems like a good enough idea for how to add more control to growing your plants, but crucial features that would enable that control are missing. The total lack of light control being the big one for me. Why not allow the user to adjust the time the light is on during the grow, or allow the user to change the brightness of the light schedule? The app makes it look like you could change that, so it must have been something they had in mind.

As well, the ability to log events in the calendar (like when water got low) would enable you to track how often one is likely to need to water - something that would be invaluable when traveling and unable to add water at a moment's notice.

The app is promising but seems to have been cut short of features to get it out the door. Please update it and make it what it was (I assume) meant to be.

The perfect solution for small space gardening ☀️😍

I LOVE this growing system! There are some benefits and some disadvantages I have found when using this but overall my experience is very positive! The benefits - This is perfect for my small space low lighting apartment lifestyle. I have always been a plant person, growing in my garden growing up, however when I moved to a small space there didn’t seem like a lot of options to continue my passion for that. Until this. It is beautifully sleek, very compact and doesn’t stick out like a sore thumb in my apartment. The success of my plants has been great! I have grown herbs, flowers and leafy greens. And it is super easy to set up! I also love how you can control it with the app. The disadvantages - I would love for seeds to be purchasable on the app. I also could not screw the system together (not by drill, screwdriver, of the piece they give you) It holds together without it but obviously would have loved for it to be more stable. Because this system is also 24 hours, I believe that it is using a substantial amount of electricity. My bill for electric seems somewhat higher, so for the cost of growing produce and flowers vs. electricity, I’m not sure if it evens out. Other than that, couldn’t recommend the product more and can’t wait to see what Miracle Gro comes up with next!

Just got it

UPDATE: I got another device and set it up. It was fine for a few days then suddenly today I noticed that the first device disappeared. Also when I only had the first device it keeps on disconnecting from the phone when the water level becomes low and would not turn off the light as scheduled since it got disconnected from the phone. When I didn’t know what was causing it I tried closing the app, uninstalling and reinstalling it ad even turn off and off the miracle gro twelve. This didn’t solve the issue. The device is great but the app has a lot of bugs and crashes all the time. I wish they can fix the app as I really like the device itself. It is just frustrating to always reads the devices and the plants when it loses the information you already supplied.


I am loving it, but I echo some of the reviews that we cannot customize the time the light is on (if I wanted less than 14 hours for example) or how long the override can be done. Also I have been trying to add a plant not listed but it is giving me an error saying to check my internet connection. Also I was trying to change that I have already fed with the supplements but I don’t seem to find a way to update it.
