1) First regarding to the floor, I understand that the wall is best to extended to 4' into the ground. But that is a lot of digging. Would 6" extended (wall) into the ground work? I will also put a concrete block on the floor. Would that reduce the heat loss to the ground? I prefer to have less digging if it is possible.

NO. 6 IINCHES WON'T DO IT. THE FURTHER DOWN YOU GO THE BETTER. CHECK OUT THE SWEDISH SKIRT MENTIONED IN THAT ARTICLE. MINIMAL DIGGING. MIGHT BE AN ALTERNATIVE OPTION FOR YOU.

2) For the wall and top, I will start adding the greenhouse bubble wrap on the inside of greenhouse. I'm not sure about the thickness yet. Could 6 mil greenhouse bubble wrap thick is enough? Should I add another layer of bubble wrap on the outside of greenhouse as well?

THE MORE BUBBLE WRAP THE BETTER. THE AIR IN THE BUBBLES IS WHAT PROVIDES THE INSULATIUON. (THE REFLECTIX ON THE EAST AND NORTH WALLS/CEILING THAT I MENTIONED, WILL PROVIDE MORE INSULATION THAN BUBBLE WRAP ON THOSE AREAS AS YOU WILL NOT GET ANY GAIN FROM THOSE DIRECTIONS.) BUBBLE WRAP ON THE OUTSIDE WOULD MOST LIKELY GET DESTROYED IN THE WINTER WEATHER. I HAVE HEARD OF PEOPLE USING AN INSULATED, CLEAR POOL COVER ON THE OUTSIDE. MUSH MORE DURABLE. (THINK OF IT AS HEAVY-DUTY, RUBBERISZED BUBBLE WRAP.)
