Research and build second generation hydroponics basins to rapidly grow crops indoors regardless of the terrain or weather outside. The second generation provides double growth, and when used in an optimal setup including one sunlamp, consumes only just a little more power, construction resources and work than two first generation hydroponics setups would. Ideal for when you don't have enough room for multiple hydroponics basins, but can provide power and required resources.

You need to include more details.
What does it change?
Research/tech requirements?
How much does it speed up growth?
Compatibilities/Incompatibilities?
Change: it adds new hydroponic basins
Research: iirc one additional hydroponics
How much: The second generation provides double growth, so that's half the time.
No incompatibility afaik
