I like multiday backpack adventures and wild camping in remote places, but in Scotland I also often just go by car, pitch my tent on a commercial campsite and make long day-hikes from there. In that case there are no weight restrictions so I just bring a 3-person tent (Vango Tempest 300) just for myself
And I can fill the trunk of my car with all the food I want and lock it safely against rodents (which are a problem on commercial campsites).
To deal with midges in that case, I found that mosquito coils are really effective. Within a few minutes it kills all the midges that are perched on the inner tent and in the porch area, so lighting the coil is standard procedure before I exit my tent in the morning. It also enables cooking in the porch area. Midges are still annoying but these coils reduce it greatly.
