It'd definitely be a recirculating system with a large reservoir... pH will stay more consistent too.

Would just have get a good mix of nutes/water for the plants to uptake so that when levels fall, it retains that same balance.

Other than the hydro system, someone's gotta be around to move the light up so they don't get burned..... unless you know how fast the plants will grow and build a light mover to raise it tiny bits at a time to match it.

like WH said, you can spend a lot of money getting everything practically automated. And lot of work fine tuning it for the specific strain before you can 'set it and forget it'
GreenDestiny Reviewed by GreenDestiny on . What's the most hands-off method? I was wondering... is there a hydro/aero method or nute schedule that doesn't take much maintainence? I don't want to use soil but I also don't want to have to check pH, TDS etc constantly. Any tips are welcome. Rating: 5
