Guys, I am just asking hypothetically, if only one method of feeding for aquatic plants was done, through substrate or water column, which would produce better growth results?
I know you can have the best by doing both methods, but again, just hypothetical.
Reason I ask is because I read, Greg Morin at Seachem (I tried to not mention as to not put pressure on anyone) said that plants uptake 4-400x more nutrients through their roots.
Here is a article that mentions this as well
But I have heard other people mention this (I guess it was other people regurgitating this info from a seminar to others). I am not sure if his info is scientifically factual or outdated or just a con to sell products (although Seachem sells both grow substrate, root tabs and water colum ferts, so that seems unlikely).
And again I know heavy root feeders would appreciate substrate feeding more than other plants, but I mean other aquatic plants in general.
Maybe I am asking if the plants uptake 4-400x more nutrients through their roots is true or not? If it is true, then I would assume substrate feeding would produce better results. But from a couple experiments I have seen, I am not so sure that is true. There are tons of solely EI dosed tanks out there, so....
Just curious, by no means am I trying to just use one method.
