Buying plants is easy. Growing them is hard. The whole joke about the "green" thumb and lack of same in TV shows and movies is usually relegated to men, but there are also few women who really know how to make a houseplant or garden look its Sunday best. That\u2019s where Parrot\u2019s Flower Power Indoor Outdoor Bluetooth Smart Plant Sensor comes into play. You'll be out in the garden so much, you might want to also consider the best wheelbarrow. If you want a different way to grow plants inside, take a look at our fluidity dish rack concept grows potted plants review too.

The Flower Power app (Apple\/Android) takes care of all this since it's a computer program at heart devoted to the proper upkeep of plants. And while in the past that meant that the computer did all the computation for the program, now it's done through the computing power of a smartphone, but not alone. Similar to how Apple\u2019s Siri voice program calls on servers in the "Cloud" to provide computation power, the Flower Power app does the same. And since the use of WiFi to access the "Cloud" can be replaced by a cellular signal which can take over when a network isn't available, Flower Power isn\u2019t restricted to indoor use alone. That's more than convenient in my case, since my wife\u2019s plants, which I have been given caretaker status of today, are now in her brother\u2019s backyard due to the fire our apt building had a while back. So I didn't have to be concerned with accessing a WiFi network. If you're looking for a convenient place to keep your plants, you might also be interested in our review on the Pikaplant One (makes keeping plants as easy as possible).\r\n\r\nThe app has a number of functions but realistically two modes: the first is information, such as the type of plants that Flower Power might be called to service, with the second being a "Live" mode which allows for real-time (or nearly anyway) monitoring. I had taken the Flower Power out of its flowerpot-like packaging and twisted off a knob in one of the two "stalks" to insert a "AAA" battery into the battery compartment (the manual doesn't say this is waterproof but I bet it is). A small LED in another stalk began to blink blue, and so I followed this up by pairing it with my iPhone. The LED went out. I then went to one of the plants and thrust the bladed ends of the Flower Power deep into the soil.\r\n\r\nReturning to the app, I watched as information was gleaned and transmitted to the iPhone and displayed through the app. As I hadn't watered any of the plants as yet, I was curious to see how much moisture was left -- so as to get a better idea as to how often I needed to come to water them, and also whether the amount of watering I had done was sufficient. The reading came back as being 24% which, while not heinous, seemed a bit low to me. The app also noted that information was being sent to the "Cloud" and that in about a day I would receive more detailed information as to how the plant was doing (the free account on the website also provides more information about how best to use Flower Power). The blades in the soil also provide details about the fertilization that the plant has, while the above-ground parts of the Flower Power dealt with the temperature as well as sunlight levels. All this information can be compared with the "ideal" amounts as per the app's understanding of the plant in question. And speak of understanding, it is hard to comprehend this invention that we reviewed which is titled the Hay fever hat: Another bizarre Japanese gadget.\r\n\r\nI took the Flower Power out of the pot and inserted it into other plants \u2014 altering the profiles that the app was reading to accommodate a new plant.\u00a0 Once I had finished doing this for a number of plants, I watered and left.\u00a0 I returned a few days later and the iPhone synced with the Flower Power once I came into Bluetooth range. I checked the readings of the same plants as before -- to find that the moisture level had increased to what I felt were more acceptable limits. I also viewed other statistics and saw where I could improve things by moving some plants to take more advantage of sunlight and the occasional rain that we in southern California have been getting recently. And consulted the app which had made predictions based on how they would be over a few days time. This affected me when I went back, by the way.\r\n\r\nBottom line: The Parrot Flower Power Indoor Outdoor Bluetooth Smart Plant Sensor is a clever and sophisticated plant sensor within a whimsically shaped construction. In use with the app, viewing and planning for the health of your plants becomes less a chore and more an easy path that doesn't require a "plant doctors" degree. Bluetooth thumb, anyone?
