85 Days. KBX tomato is the potato leaf version of Kellogg’s Breakfast. These two tomatoes are similar, except that I have found them to be a bit more prolific than the regular leafed version! KBX tomato is meaty, big and sweet. It is a great selection as a main crop for tomato vendors. Plants are about 6 feet tall and produce high quantities of deep yellow, (sixteen to twenty four ounce) fruits, that can really be used for many things. One of the the best for sandwiches. Great for tomato lovers who are seeking a lower acid fruit with great flavor and plenty meat! Click Here To See It On YouTube!
