Hello bud, 😁,
So
@organoman is right the plant needs direct sunlight for best results you need about 18hrs and thats not possible outside.So what ever hours of light you can get you should optimise on it by putting the plant somewhere where there is sunlight for majority of the day.
If your keeping it there for heat you might need to invest in a small heater and move the plant, the plant needs correct temp, light, water and nutrients, thats also probably why your previous attempts weren't successful.
Its harder to provide more info because we dont know what kind of plant it is to say exactly what would be best.
My gorilla zkittlez auto had same issue because of light untill i sorted it, now she is growing beautifully,
Hope this helps,
Happy growing mate!
