You must have AQUA BLOCK and ROCK to make JEANS. This item belongs to pants category. No need for growspray here, will be done in a jiffy. Received experience is a mystery. Keep an eye out for the exp counter. JEANS can be broken. You get at least 1 seed back (maybe more!) from splicing JEANS. Will you strike it rich? You just have to count the gems yourself. Will you get enough blocks to build something? You just have to find out yourself.
