I must disagree. I went to my hydro store to by sum flora necter but i wanted the gallon size and it was 55 dollars. the salesman showed me the back of the bottle which has the formula and the ratios. It was Molases, cane sugar and malt extract. I bought the ingredients at wholefoods (i couldnt find the extract but it was only a small percentage of the formula) and I made my own mix for a tenth of the price. Flora necter works in hydro, you just have to make sure you change the rez once a week. Also I am using ebb and flow so I don't really have any lines to clog. Flora necter is comparable to Sweet or Sugar Daddy. Sugar is good for plants in hydro or soil.
