One day i was tired of buying fresh herbs, but unluckily i live in a apartment, where there is not direct sunlight most of the year.
Also i am a lazy guy and i wanted some kind of supervisor of the plant health and status, to track the plants, and automatize as much as possible, while its easy to setup
So i decided to create a tabletop planter which could give enough light to my plants, and also upload some stats and and images to a server.

Main features of first version:
- Smart home integrated (Homeassistant).
- custom PCB with only thru hole components (easy solder).
- Based on ESP32cam so plenty of implementation examples available.
- Fully 3d printed frame.
- High efficiency and dimmable LED Driver.
- 180 lm/W Led strips.
- Adjustable Height.
- OLED realtime status show.
- Easy OTA config with ESPHome, easy automation creation through nodered.
- I2C Pins exposed.

For full build guide take a look out on my blog :

  • Diving into firmware

    Niko • 06/24/2020 at 11:51 • 0 comments

    Put all the pieces together and finally build a working prototype.
    Time to buy some seeds and test it in real conditions.
    I used a ESPHome firmware to add the controller to HomeAssistant.
    The next is to create some automations for the system in Nodered.

  • First prototype built

    Niko • 06/12/2020 at 11:38 • 0 comments

    In last to months i have so far:

    1 - Soldered all the components to the PCB board:


    2 - Updated the design:

    3 - Integrated the esp32 as a component to HomeAssistant using ESPHOME:

    It was a success except for the camera integration.  

    4 - Mounted the first prototype:

    So i´m ready to test it in next weeks :)


  • Started working on 3d pieces and rendered models

    Niko • 04/16/2020 at 15:53 • 0 comments

    Started working on 3d printed pieces, also i created some renders of the boards and setup

  • Sent to fabric first prototype PCB

    Niko • 04/16/2020 at 15:52 • 0 comments

    I created a schematic, and using autodesk eagle i created a first prototype of the PCB.

Is there enough UV in the spectrum from those LEDs to give the plants what they need? Seems like grow lights always have a bit of a purple tinge to them, so I always assumed a little UV was needed.

  Are you sure? yes | no

It would be better to give the plants also UV not present in this lights, but it would make the build more expensive and complex, UV light is less than 10% of what is called PAR or "photosintetically active light", which is the spectrum that a light plant uses, also depending on the plant and strain, and in where the plants receive that light (stem, leafs, top leaver, bottom leaves, etc.. ) it gives different results, also some far red light would be better, but you can raise a plant with just white light.

  Are you sure? yes | no
