Trying to buy a device that will do both pH and EC so I don't have to carry around multiple. Price doesn't matter all that much. I do want quality and accuracy.
I am modifying my Power Grower RDWC systems to have a 13 Gallon Reservoir. And in general my tendency has been to make my PPM stronger then what they actually consume nutrient wise! I have done this because they don't seem to burn and because they can consume the whole entirely of the reservoir in one day at their peak flowering cycle. In Veg my plants can drink as high as 1400 PPM which seems crazy. But as soon as I flip the light cycle this drops to about 600-700. .5 conversion And I...

I am wondering if AISI-302 stainless steel parts are suited for permantent contact with the nutrients? It is because I am thinking about using a non return valve which in the reservoir which has AISI-302 grade parts. I don't know how aggressive the nutrients are to metals and if this kind of stainless steel might bleed toxic stuff into the reservoir.... Any idea? April 22, 2019 at 04:01PM Read more about this fix

I've been keeping track of the runoff and two of my girls now" the ones that are showing the rust spots and a slight droop...
