PPM, PH, FLUCTUATE what mean?!

So what would be my ideal ppm in an aerogarden ? I was running 800-1000 at a 5.4 ph and they all died I'm going back to California soon and want to try a again

If the plants aren't established, you can run a much lower PPM, like 500 or so, depending how much of that PPM is from your tap, then judge from there how hungry they are by using above said methods of measuring PPM. One thing i found is 5.4 pH is too low; I go at 6 because I realized in hydro the pH drops down throughout the day, so if you water with 5.8-6.0 ppM water and find the pH dropping to 5.5 before next watering you are in a great zone. PPM can be upped as the plant gets better. I run 1000 ppm for full sized plants and it is almost too much but just about perfect with gh trio

if the aero garden is non recirculating (drain to waste) you can probably go higher ppM than a recirculating system. aero systems are typically drain to waste
