Hello fellow mushroom enthusiast. This strain of cubensis was picked by BIO in Australia some years back and produces some very healthy, classic text book, golden top cubensis. It has potential to grow some very large fruits at times. Sometimes excedeing 1 foot in height on simple substrates such as birdseed. Usually it will produce a varied amount of vary large fruits, or a huge abundance of average sized fruits, using the substrate very well. On DB compost it we have seen it produce fruits over 18" tall. This strain does excellent on DB compost. Its colonizing speed is average, not breaking any records, but certianly not slow. Another nice characteristic of this strain is it produces very thick, solid stems. We have also found over time this mushroom is very comparable to the ecuador cubensis in many aspects.
