As a grower, most of you won’t look at a PCB or care about its design details, so I’m sharing this in terms of what it actually enables in a hydroponic setup rather than the electronics behind it.
I’m sharing a custom all-in-one automation controller PCB I’ve been working on specifically for hydroponic systems, and I’d really like input from growers, builders, and anyone working with controlled environment agriculture.
Most hydroponic setups end up relying on multiple separate modules, timers, relay boards, sensor kits, controllers, power supplies, all wired together. Over time, that adds wiring complexity, more failure points, and makes scaling or troubleshooting harder than it should be.
This project is an attempt to consolidate the core automation stack into a single integrated platform.
What the system is designed to handle:
- Central control for hydroponic automation (sensors + actuators)
- Monitoring of key environmental and system parameters
- Control of pumps, valves, lighting, and other loads
- Remote access for monitoring and control
- Time-based automation (irrigation cycles, lighting schedules, etc.)
- Mixed load operation (low-voltage signals + higher-power switching)
- Expandable architecture for future upgrades and interfaces
- Designed for stable operation in humid, real-world grow environments
Target use cases:
- Hydroponic grow systems (small to medium scale)
- Indoor farming setups
- Automated irrigation systems
- Experimental or modular grow environments
Feedback I’m looking for:
- What would you improve in a system like this for real hydroponic use?
- What failures or pain points have you faced in your own setups that aren’t addressed well by existing controllers?
- What features are actually essential vs. unnecessary complexity?
- Any concerns around reliability, scaling, or real-world deployment that I might be missing?
If anyone here is looking to automate their hydroponic garden or is already working on similar systems, I can also help with design, PCB, or automation setup ideas.
