Splice DARK GREY BLOCK and OPEN SIGN to make STADIUM. This item belongs to race category. Well it is still less than a week to grow STADIUM, chin up! For basic breaking and levelling up. Hitting it will break it but you need to count the hits yourself. You get at least 1 seed back (maybe more!) from splicing STADIUM. Profiting with this might be questionable. Massproducing STADIUM can be tricky. You will find out after you have harvested a few.
