Reposting a few basics based on Genesis 6:14-16: the ark was c. 450' long, 45 feet high and 75 feet wide with 18' high windows for light on the top of the side walls. Thus there would be 450 x 2 + 75x 2 = 1050 feet in length. Subtract 50 feet for the 4 corner windows with branches of 4 trees protruding out some of the windows. Likely the exact corner windows had 2 3' window boxes in each corner for plants prefering more sunlight, and the trees would have a base of about 5' deep 25' x 25' boxes on the floor of the middle level for the roots of these 4 trees, sloped down at first, then filled with compost and eventually sloping up.
These 4 trees could be planted before the ark was completed, and would be timed for fruits ready for harvest within a week of the start of the flood. Those 4 roof sections would be the last constructed so the trees had plenty of sunlight until just before the flood. The window boxes could be planted outside the ark and brought inside right before the flood.
How many window boxes? Assuming slightly over 999' length the 3' long (2' deep = 6 sq.') there would be 333 window boxes at 6 sq' each = 2,000 square feet or the equivalent of two 20' by 50' gardens. Intensively gardened and hand harvested this would produce more food than Noah and his family could eat - so likely it was shared with animals. Also many of the boxes would have flowers with an emphasis on flowers that honeybees like - since we want the ark to be flowing with milk and honey!
Another common food on the ark was probably cream of mushroom soup since mushrooms can grow in total shade. I suspect 5 cows and 2 bulls (I think the bulls would prefer 1 bull and 6 cows) - how much milk will 5 cows produce? That;s for another post!
But what types of flowers might Noah have grown for fragrance and honeybees? That is for my last post for tonight - as I intend to dream of flowers (counting flowers rather than sheep):
