If we are basing this discussion on indoor growing I hear what everyone is saying and yes if you have looked into hydro and its not your thing thats ok, but!! You talk of echo friendly practices, more expence, etc. imo that is where you guys have it a bit wrong. The statement, more energy used in hydro versus soil is pretty hard to justify imo, and I own (rent out the fields) a certified organic farm lol. Chillers, not needed, never had one! Air pumps, not needed, used one for a month, never again. Yes a water pump, very small electrical footprint, Less lights on time due to quicker growth, more buds shorter growth cycle. Cost is again a mute point, my setups (well the newest one lol) cost less than $100 and supports 6 girls, $100 bucks, really sell a half lol. Nutes are another thing, dont kid yourself they all impact the environment. This is why this thread is silly as to the direction it has taken. No one will ever win the hydro versus soil argument. There is no better or worse way to grow. There is a preference and thats ok but to defend one or the other as better is a futile endeavour, but fun to follow I gotta say lol. Also IMO hydro (if grown properly) taste better, letting the subtle differences come out. I'm just happy to done with gnats, and fucking pots everywhere, happy to not spend hours properly watering soil, spend hours potting, and then repotting again lol. Thats why hydro guys are arguing btw, the arguments presented are, its more time consuming, harder to control, use's more power, bigger enviromental footprint, soil taste better. All of these reasons are imo just here-say without true fact. Lots of that here on all subjects. Lots of growers here are legends in their own minds, lol. To OP there is no right answer for the question posed. The right answer is try all of the methods and see what you like and what works.
