DWC Beginner questions

  1. Hey guys,
    New to the forum and new to growing, I have built an in ground greenhouse in my backyard. Roughly 1.2 metres deep around 3.5 metres wide and a little over 6.5 metres long. I have a 1.4 metre wide by 800mm, concealed grow room in the ground at the back. In here I am going to try my luck with DWC. I have a couple hundred seeds here that I got off friends that I will use for my first grow, not too keen to buy nice seeds till I learn from my mistakes lol. I seen online that a fella said to prevent too colder temperatures I may use a aquarium heater in my DWC, I also thought this may promote growth of unwanted bacteria so firstly what's the professional opinion on desired water temp for my DWC. The idea is that being under ground the frost above should never penetrate below.
    I have lots of questions, if someone takes the time to answer them I'd greatly appreciate it. I live in New Zealand which is well known in my parts for having 4 seasons in one day.
