Controlling my growbox with a mobile phone

How many times have you been riding the bus and have been curious what temperature your computer growbox was running and if the plants needed to be watered?  Ok maybe never, but I decided to solve this problem anyway.  There is also no point in identifying that you may have a problem without having a way to do something about so I also implemented the ability to override the controls on the growbox by using a Windows Phone 7 application on your new T-Mobile cell phone or any other cool Windows phone.

I made the design for this pretty simple, unfortunately I could not connect with my growbox directly using a mobile device because the computer is behind a firewall (which is a good thing) so I used machine that both the mobile phone and growbox can contact cheapvegetablegardener.com.  After creating a quick web service with the following methods the growbox and mobile device could now talk to each other:

  • SetStatus(StatusInfo) – GrowBox sets this status every minute
  • SetOverride(OverrideInfo) – Mobile sets override to default functionality
  • GetStatus() – Mobile Phone gets status
  • GetOverride() – GrowBox checks for potential overrides requested by Mobile device

Mobile UI

Now I have the two devices talking here is the basic UI.  The top half of the screen shows the growbox temperature, cpu temperature, and the moisture content. All of these statues change color (to yellow and red) as their values get to critical levels (too hot, too cold, too dry)

The middle section shows the current state of the growbox letting me know if the lights, heater, exhaust fan, and/or water pump are on or off.  If a situation occurs where you want to override this state you can do this by simply clicking the status indicator.

The bottom part of the screen shows temperature and moisture levels over the past 24 hours.  The graphs are rendered using Google Charts for simplicity though am thinking about creating my own custom solution to get the graphs just right.  It also displays a current screenshot inside the grow box and you can transition between views with a finger swipe.

Though this covers most of my required functionality, I still need to add some cool transition animations and some additional analytics, but thought I would share my current version.

    is this good for growing weed too?


  6. H4x0r Says:

    @Joe,

    Yes you can! i’ve been using a system equivalent to this one for my plants…

    Please note that you cant use a default light scema.. weed is very specific and wont grow if you don’t have the right conditions…

    For the first 2/3 weeks you’ll need: 18h of light, +/- 24 degrees celsius, and a humidity of 50-60%…

    After that trow the light back to 12h of light, keep the temperture steady on 24 degrees celsius and get the humidity down slowly…
    if you dont do this you’ll get funges. if you do it to quick your plant will also die..

    In the last week the humidity needs to be around 30%

    Some last advice!
    make the plant search for its food. so: it’s better to dry out the plant than to overflow it with water…

    Is it possible to obtain the sourcecode of this project somewhere?

    For example:
    the windows mobile app and or the c++ project


  8. The Cheap Vegetable Gardener Says:

    James, cool I haven’t heard of that one.

    joe, good for other herbs…haven’t tried that particular one.

    H4x0r, I probably won’t share the source code but may share the application once I get all the bells and whistles added…might even setup a hosted service to support other’s grow boxes if there is a demand for this.

    Dude, this is sick, I wish I could come close to doing stuff like this. I am setting up a grow contest between a couple garden blogs to see how my LEDs stack up, was wondering if you wanted to put your grow box into the contest or maybe your Christmas light grow light, once again sick setup for your grow box
