I'm using the ebb&flow for pre veg before buckets, i have my cuttings that are 2weeks at 400 ppm and 5.8, with a 40 gallon rez and Ireally don't need to use it till all the roots got to the bottom, so i have been watering from the top till just today, now they are going up and looking nice, The og i have is #18 from reserve privada and I grew just 1 to smoke in dirt and it turned out to be the 1 of the best strains i have ever seen or smoked, it has it all skunky-fruity-kushy-and taste like chemdawg all at once, even if its the last black hit in the bowl or last hit on joint, I have seen only a few strains that hold true to the core and this is one of them, I would highly reccomend it to anyone who wants "aaa" herb.
