I haven`t grown either yet, but I can tell you that hydro yields more if you grow it right. You have to keep good control of your temps and nute ratios, but if you do that you will have bigger plants and more yield.
.....hmmmm, I'd beg to differ Goldie. Hydro is said to get you there quicker, but as for overall yeild.. ??? It would be my thoughts, that as long as optimal conditions are maintained in both process's, both should produce near equally. ..BUT..I am a soil kinda' guy and have near 0 experience water farming.
I like dirt. It is far more forgiving to the new/unexperienced grower, go 100% organic, and you cannot compare the flavors..."IMHHO"
After growing in soil for a period of time (haha), I'm finding hydro is so much easier to deal with than soil. Example: if you over nute you plants with soil, you will need to do a clean water flush, but with hydro just empty a pint or two of solution and add fresh water with PH adjusted, your done. Also no messy soil to deal with, I hated that part of the ordeal. Once one understands how their nutes change the PH levels, it becomes very simple and so much cleaner. Advice: TigerBloom works great with Hydro, have tried many types and none would do what (TB) would do, but to each their own.
Strictly a soil grower here, but I was under the impression from hydro growers I know that yeild is relevant to strain and conditions. Hick said what I wanted to say...hydro speeds up things a bit, but I'm not too convinced it yeilds more in the long run. I think that would depend on too many factors, and if so the differences would be slight. A properly cared for soil grow can yeild pretty well itself.
