I have a solution of plantex and one of macros. Both are mixed with tap water. Plantex is at 1tbs/500ml. Macro has is 1tbs/500ml of KNO3, and 1/2 of NO4(maybe). They are in white half and half jugs (non translucent plastic containers). I am not sure if it is the tap water, the concentration of the ferts, or the fact that they are not recieving light, but I have no growth in mine.

I can make no personal observation on excel, but have read some threads that made me use it as a possibly magic potion. I am probably going to buy some in the next month or so (perhaps the next hr to be honest - since I suspect I have a c02 diffecency in a tank and feel my ladder is maxed out.
