Welcome to the forum, Eddy! Great folks and info here!
I haven't had a full cup of coffee yet this morning so I can't tell a lot from your diagram. A northeast exposure isn't the greatest angle and at your latitude the sun will travel lower than it will in the USA, except for one small spot in Minnesota. I would only use the light coming in the window(s) for "bonus" light and rely on artificial lighting for the main light. Does *any* direct light come into the window? If so, for how long?
Pitcher plants and flytraps require the most (LOTS) of light. Pings and some drosera do not "require" intense light, but most of the the drosera (sundews) do better with high light levels. I've never grown pings so can't say a lot about their light needs. Varieties of Drosera capensis seem to do fairly well in cooler areas and tolerate less light than do, say, filiformis varieties. But, again, all will do better with good light. I think that without extra/artificial light and only window lighting from a northeast exposure that the plants will struggle no matter the type plant.
I'm not sure what is available in your area for lighting. It depends on how big of an area of plants you want to give light to. A 0.3 meter diameter circle of light/plants is about the minimum to shoot for and the simplest. Going larger requires a bit more thought. I would start with at least an LED bulb that's equivalent to a 100w incandescent bulb. 3000k to 7000k temperature is ok. 3000k will promote more flowering while the higher temperatures will promote more vegetable (leaf, stem) growth. I prefer the higher temperatures. These are simple, retail LED bulbs. There are also purpose-built "grow lights". Many of these produce a very purple light that promotes very good growth but personally I don't like the colored lights as I'd rather see my plants in their natural color...it is also easier to see if a plant is having problems under "normal" lights. But, there are also "white" grow lights. You'll find pricing on them varies a good bit. Again, like I mentioned, I don't know what's available to you. Before buying anything you might post it here on the forum ( a link to it would be great) and let folks give you some feedback on it. Even something as simple as a single, regular 100w light bulb can work for a single pot or two, though. It is not an insurmountable problem to solve.
Panman's suggestion of a Cape sundew (drosera capensis) of some variety would be great to start with. I *strongly* suggest that you start with a young plant so to keep your interest going. But, be sure you check the seed bank out. Free seeds for the cost of postage!
Here is a link to the Seed Bank Inventory:
FlytrapCare Community Seed Bank Scroll down towards the bottom (below the seed listing) for instructions on how to request the seeds. If you have questions about the process...just ask.
I'm not sure about how the bonus and all works internationally so inquire about that.
Best wishes and welcome, again, to the forum!
