I don't buy the soil/hydro myth of less THC. I have grown both extensivly and had varied results. Both are awesome and it depends on the strain and the grower. I had some sour diesel that was soil grown and it was not even close to the 'dro diesel. I had blues growing in both and both rocked. diff appearence same monster stone. So to each their own. I like hydro for the control it gives you. But by all means keep growing in whatever the hell you like!!
