How long are you guys getting out of the diaphragms on this pump? I recently upgraded and only got a month and a half out of it before both the diaphragms were shot, now I'm waiting a month for repair parts... Maybe I'm running it too hard, only using 6 of the 10 outlets?

I am

I'm having some percipitat issues in my rez. Running jacks 321 in a rdwc system that also feeds a drip system. I have somewhat hard water 300+- ppm, and when I add nutes the rez pH rises overnight from 5.6-6.0 to over 7. When I adjust in the morning the rez is cloudy, almost milky, once pH is...

I think what you're saying is exactly what I'm trying to avoid... lower voltage less efficient 6.6a @ 120v 3.2a @ 240v And I'll be using 240v directly from my panel with no additional transformers. According to the amps to watts calculator, I'll be saving like 60-80 watts per light at max draw...

I have 240v available, I wouldn't be using a step up transformer....

Double the voltage = half the current, so the light will use have the amps at double the voltage. And your paying for amps not volts Edit: watts are what your paying for

"but efficiency may suffer on lower voltages." What do you mean by this? I actually just got a reply from mars, they are automat switching (sensing). Thanks

I wanna run my lights on 220-240v to save some money. As they're listed to operate on an input voltage of 120-277v. So, does anyone run their mars hydro light on 220-240v? If so, do the drivers automatically switch for power input, or do I have to open it up to manually switch power input? Thanks

End of week 8 update. I don't what exactly the issue was or combination of issues, but I'd consider it slavaged. Thanks all

I stuck a thermometer into the bottom of the pot and its 67⁰, I put a foam floor mat under it and turned the light down a little. Is it safe to assume if it does recover I will only see progress in the new growth?

Thanks pH has had very little fluctuation, and even with slight changes of a couple tenths, the soil slurry is always 6.5 +/- .5 (I'm using a lab quality pH probe that I am very confident with. I've been using the same model for years and they are always spot on when maintained properly) This...

I'll give a shot. Think its salvageable? Thanks!

No change in lights pH is calibrated every use. It is sitting on a cold surface, 65⁰ +/- concrete floor.

I'm confident that I'm watering slow enough, the lower fan leave dont appear to be thirsty, except lately right before a watering, because I've holding back... I'll try to up the watering and see what happens

Thanks everyone. At this point I think I'll try upping the watering, and cutting out calmag.

No, just waiting for the lower fan leavs to slightly droop before watering, thats what I've been doing for the last three/four waterings (week and a half ish). And I was only doing that because it seemed like a symptom of over watering. However I haven't tried to increase watering. Well hasn't...

Thanks Would you suggest cutting the calmag out totally? Salvageable?

I've tried searching the symptoms everywhere, and haven't been able to solve this. Sorry for another "one of those" threads, but I did try to figure it out myself. Thanks Leaves are curling down, started after the first week of flower. I thought at first it was over watered, but I've been...

Right now I'm using pla.

The files aren't quite ready, I don't have all be bugs worked out, but if you want em I'll throw em up on thingiverse I'll add a link when I get em up.
