I tried that website, I don't have a home computer I can get online using my hand heldphone. So I guess tha website doesn't fully show up thru cellphones. My main question is when do I test the water. Do I test the water before or after I add nutrients to my water? How often do I test the water? Last, I have that 800 PPM solution (which came with no directions on how to use it) when & how much do I use tha solution? That's mainly my main concerns. I know how to use the tester now, I just don't kno when to use it & when & how to use the 800 PPM solution.. I can't get started to I fully understand what I'm doing. Is there a forum where it explains step by step on growin thru my cabnet system.. I have tha indoor bible but for a 1st timer its like readin in a defferent language...
