Got started already, or just want to learn more? Tune into the live stream Grow your own with Raspberry Pi - Alex Ellis & Richard Gee
- Read the launch blog post: Join the Grow Lab Challenge.
- Order your kit, or decide you're taking part by sending a PR and adding yourself to the "growlab Technicians" section below.
- Build your own
#growlabusing one of the designs, or customise it. And start growing and recording a timelapse. - Use the #growlab hashtag and share as many pictures as you like.
- Send a Pull Request and link to each Tweet to unlock each level.
- At the conclusion of the growing period, we'll send some prizes from OpenFaaS Ltd and Pimoroni to entries at random for different tiers.
Prizes to be provided by: OpenFaaS Ltd and Pimoroni. Want to sponsor or provide prizes? Send an email to alex@openfaas.com
Bronze - assemble your #growlab using one of the recommend designs or customise it. Tweet a photo of your build.
Silver - install the software and capture your first photo of your seeds in the soil. Tweet it using the seeds2 software, or copy the file to your computer and Tweet it from there.
Gold - Wait until at least one of your seeds has germinated, and Tweet a second photo.
Platinum - use the phototimer or seeds2 software to capture images over a week. Compile the images into a timelapse and upload it to YouTube. We recommend one photo every 10 minutes. Tweet a link to the video.
If you're using phototimer, then you can run the following:
echo $(echo $(find ./Desktop/image/ | sort -V|grep jpg)) | xargs cat | ffmpeg -framerate 10 -f image2pipe -vcodec mjpeg -i - -vcodec libx264 out.mp4iMovie is also relatively easy to use, by dragging the images into the timeline and changing the time between images to ~ 0.1s
Here's a sample from 9th-22nd April you can watch on YouTube:

A self-watering system
- Overlay temperature and humidity data with an BME280 sensor
- Add a self-watering system with a small pump and capacitive soil sensor
- Try a garden RGB grow-light to give your seeds a little more help
- Experiment with hydroponics
- Install your lab in an outdoor greenhouse, shed or cold-frame
- Use a light sensor / LDR or UV sensor measure available light
- Try a suitable solar panel and battery capacity to run your experiment outdoors or in a room without a socket
Technicians work in laboratories, and you are no different, so if you've bought your kit, or have decided to join, then add your details below so that we can encourage each other and see how many people are participating. If you don't have a Twitter or GitHub handle just put N/a.
If you have a Grafana dashboard, or a HTTP server that you'd like to share, then apply for an inlets PRO trial and say that you're doing a growlab, and we'll send you an extended trial and host a free exit-tunnel server for you. That way you can share your dashboard or images on the Internet. Apply here
Once your tunnel is up, youcan serve the directory directly from phototimer with inlets-pro http fileserver --webroot /home/pi/image --allow-browsing --port 8080.
