If i'd want to go and grow vegetables in my basement, where it's around 15 degrees Celcius ... would it be sufficient enough to heat the water, or would the environment need to be heated as well ?
I'm thinking lettuce, radishes, pea's / beans.

Heating the water is a big no no. In the ideal situation your nutrient solution is about 18 degrees Celsius to prevent root rot etc

Temperatures are fine, however lights may cause a significant increase.

Everything you mentioned but the beans prefer cooler temps.

Check the preferred growing temps for all, probably they would need some additional ambient heat (and light!)

You are good to go. All. Basements stay about the same and I grow in the winter to supply my greens and other specialty crops

      Need a lot of light and a couple fans for circulating air and exhausted out of room. Pretty much anything will work inside with the right light. Temps swing from 64 to 80 each day in my grow room.

      Have 4 grow beds stacked and 6 light bars on each row with lights 8 inches off plants. Still could use more lights for faster growth. I'm supplying 10k lumans.

      thanks for your reply! Are you using LEDs? And is that an NFT system?

      yes it's a dwc nft system. I am running 4k 13 watt led shop lights. They work great for greens. Local energy efficiency programs are great. 3 bucks each.
