For those a bit confused: Ancient hydroponics grow thing sin them at 140 pct rate, just like rich soil, without any nutrient input. Base hydroponics grow at 280pct, just like they always did, without nutrient input. IF you provide nutrient input (you do not have to), then the plants get a periodic free boost to their growth percentage, there is no shown difference in growth rate. There is no downside to not using nutrient. You do not have to use nutrient. If you do use nutrient, things grown faster. The ancient hydroponics can even grow a wider variety of things and do not cost power, so they're still very valuable.
