Set up: It claimed that I would be able to set the system up in 20 min. I was skeptical, but I timed it, and it really did take 20 minutes (23, but who’s counting! lol) If I can set it up, anyone can. It was really a matter of 8 screws, and the rest just popped together.

App: The app helps you set it up, giving detailed, step-by-step instructions that we super easy to follow. And, then it syncs to your phone so you can control the system from your smart phone. It will tell you when you plants need to be watered, it automatically schedules the growing light, and it tells you when to add nutrients. It also will tell you when your plants are mature and ready to harvest. So cool!

My Garden: I decided to start with small plants from my local garden shop. I got basil, rosemary, yellow cherry tomatoes, and mustard greens. Planting them in the system took like 5 minutes. I can’t wait to have a continuing supply of fresh herbs, tomatoes, and salad greens, growing right in my kitchen. This is a food lover’s dream, right?

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!

Super cool features

This app is so cool. It tracks how much water is in the system, programs the light schedule, has a calendar for harvesting the plant depending on the type, and when to put nutrients in the water. This app does all the hard work and planning that goes into growing plants it’s crazy cool! It was super easy to understand and helped set up the system by showing step by step what to do. Can’t wait until we can order plants directly from the app!
