CanGrow
A simple DIY plant growing system (for cannabis).
WORK IN PROGRESS
Motivation
I want to build a simple grow system, which I can power by my off-grid 12V solar system. So this project is limited to a small 40x40x120 tent for one plant with a 50W 12V grow LED light.
As I did it for my solar system, the measurements of this project will be shown on my website. For that a REST API is planned.
I want to automate as much as possible which makes sense and is easy to build.
Features / ToDo List
- Measure values ✅
- Humidity ✅
- soil moisture ✅
- temperature ✅
- water level for water tank ✅
- LED grow light control (on/off, dimming, max. 12V 50W load ) ✅
- You can of course use a relais as well, if you want to drive 220V lights ✅
- fan control (on/off, (PWM?) max 1A) ✅
- pump control for automatic watering (max 1A) 🔵
- Web UI and REST API for data and controlling 🔵
- simple web ui ✅
- REST API 🔵
- Send notifications with web call (e.g. for mastodon) 🔴
- predefined grow profiles 🔵
- persistent data ✅
- Start of Grow ✅
- day of grow 🔵
- grow profile
- watering amount per week 🔵
- light cycle ✅
- wifi settings ✅
- settings in general ✅
- Easy to build and use for beginners (i hope so!) ✅
- PCB layout to order from manufacture (jlcpcb or pcbway) ✅
- easy to build up on a perfboard ✅
- easy to etch pcb ✅
- easy to access and modify ✅
- low cost as possible! ✅
✅ Done - 🔵 In Progress - 🔴 ToDo
