Hey Llorgon..how are my frags🙂
I just started dosing this March. I also tried using the same Brightwell products at first & found it didn’t work well for me. First of all, I needed fairly large doses initially to bring the low numbers up and the bottles were quickly depleted before the numbers were even where I wanted them to be.
After looking at various options I decided the BRS stuff was the simplest for me. I used their calculator and watched the instructional videos to walk me through. Those initial doses were quite hefty but necessary to get the parameters up there. I’m happy with their product, both for cost and ease of use. Not sure if you buy a lot from U.S. online though.
