pH drops like a rock daily!

Hi guys, this is my first post, maybe someone is able to shed some light on this issue.

I've been a grower for the past 5 years and always managed to find a solution when pH is increasing or decreasing, HOWEVER in this particular grow I am completely out of ideas of what is causing such issue.

Basically pH drops on a daily basis from 5.8-6.0 down to 4.1-4.4. This issue starts after 4-6 hours when I pH adjust the water or replace the water completely is stay stable for that amount of time...

Just soak your netpot every few hours to keep things moist... The root system will establish itself and you'll see... Germination of seeds - ready for r/dwc from Hydroponics / Aeroponics read more

Is AISI-302 stainless steel good for the reservoir with nutrients?

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
