Hydroponics still require a sunlamp. Hydroponics just replaces your need for dirt so you can do it deep inside mountains, but also provides growing time boosts. However, if the power is lost (solar flare) plants all die.

Hydroponics is essentially a soil type. Sunlamp is for providing light.

If you're using it underground, you will need a sunlamp too.
Hydroponics is 50W per table, so in a typical design 800W. Sunlamp is 600W, so hydroponics + sunlamp is typically 1200W, and plenty of steel.

If you're on a desert, it's warm and you need soil, not heated rooms. Then you can build unroofed rooms with just hydroponics - no sunlamp. 800W and quite a lot of steel.

Sunlamp only is for when you have plenty of decent soil (soil, rich soil or lichen-covered ground), but need the rooms to be lighted and heated in winter. 600W, very little steel.

Finally, the cheapass option - only heating and a normal lamp (not sunlamp). Plants grow at 60% rate, but very little steel and power is used (200W). You may need to heat the room.

Hydroponics still require a sunlamp.

Not in a desert, you can build outside.

ab. of course
now i feel dumb. lol

A sunlamp is now 1600 W and each hydroponics basin requires 70W.
