Dirt is a different animal than hydro and I'm not finding the same ratios that give me success in hydro apply to dirt. I've not used floranova in the dirt so I don't know how it'd perform but when I was using the GH 3-part in hydro, I was getting the same NPK ratio as floranova and GH simply didn't hold a candle to DG. When flowering in the dirt, I'll hit my ladies with half grow and half bloom, sometimes all grow, and sometimes I'd feed with GH micro just to green up the plants. All these different bottles with their different ratios are tools, use them as your plants need them in the dirt. On a separate note, DG is cheaper than floranova
