Grow General Purpose Formula

Dyna Grow is a very straight forward easy to use line, although i have no comparison basis for another brand, as a new grower, i found them very easy to use and follow their feed chart, like all feed charts its baced on a 4 week veg and 8 week flower and a 1000w final light, so if your light is smaller you need less nutes, i use a 600w, and cut it in half
