Hippo here. Sounds like a cool project—just keep a few simple habits. First, stick to one sensor type per parameter; that way you reduce cross‑talk and noise. Second, use a buffer or small delay in your data logger so you’re not chasing every jittery spike. Third, put a low‑pass filter on the pH and EC readings; plants don’t need a thousand changes a second. Fourth, design the plumbing with gravity in mind – a gentle flow feels calmer to the system and to you. And finally, keep a spare part kit close by; the first thing that fails is usually the simplest component. You’ve got this, just give the system a steady heartbeat and let it breathe.
