Which
Botanicare line? They have the CNS17, Kind, and Pure Blend lines. Why changing from Dyna Grow? To be honest, both companies make good products but you won't get significantly better performance by switching. Kind is a good 3 part formula, easy to use in Coco. Pure Blend Pro can be used in coco but depending on your water (and skill level) you are more likely to have issues with deficiencies. I switched from
Botanicare to GH after I decided to look up the heavy metal content of my nutes here:

GH Flora series, Flora Nova series, and Maxi Series all have "non detectable" levels of arsenic and cadmium-just something that is important to me. I have a zero tolerance policy towards heavy metals in my nutes. Good luck!
