Should I post a "review" in the reviews - lighting section for the HLG test I did earlier this year? I didn't think to add one separately but I could easily copy & paste some of the images etc... It is discontinued but as an overall quality of HLG products, it may be useful?
I have been having luck making my nutrient mix at maximum strength with plain tap water that I let sit out. Then I water the nutrient mix down with ro/di water until it's at my desired ppm. The ph stays stable for days this way.
I fill up a 5 gallon bucket and let it sit out for 24-72 hours. Has been super easy. I don't think I am going to treat seedlings this way. They will get Ro water. I feel like this is something I can get away with when plants are mature.
