Ok guys, I need a little help with something here because the math just doesn't add up, or maybe it does and its EXTREME. I just went out and purchased some Big Up powder for my RDWC system. I am running an 8 site, 13 gallon Undercurrent setup, which comes out to about 117 gallons (including the epicenter). On the labeling it says to add 1/2 tsp for every gallon in my system. Now most people will ALWAYS say "always use half strength when it comes to DWC". Fine and dandy, but even at 1/4 tsp for every gallon, thats 29.25 tsps!! 
. I definitely am cautious when adding nutes to my RDWC because I know that when I go to top off with water and add the nutrients, 300 ml(dutchmaster a&b) will take the ppms to over 800 (when my system is almost near empty).
So now my question is this. For anyone who owns an Undercurrent system or any other type of RDWC (or even DWC), how many tsps of Big Up powder do YOU put in your water per gallon? Thanks!
