There is an excess of spent mushroom substrate (SMS) in agricultural farms worldwide that has been wasted instead of used for the cultivation of other vegetation. SMS has many natural benefits that could be used instead of fertilizers that can cause/have caused side effects in nature. When looking online there is many articles about how SMS can be used, and some farms might actually used SMS. Yet, there is a lack of articles covering side effects or results. To answer this question, an experiment was conducted with grow kits that had Pleurotus Ostreatus (oyster mushroom) substate and each was put in out in the sunlight for varying amounts of time. There was 3 kits used, Kit #1 was the control and was put out for 2 hours, Kit #2 was kept inside and not put into the sun at all, Kit #3 was put out for 4 hours and this was in the span of 11 days. This research was conducted to see if it would make a difference in the conditions set, this would help discover if SMS could be used in most/all agricultural farms. The goal of this research is to find a better incentive or alternative to fertilizers and other harmful products used for the cultivation of vegetation, one of them being SMS (which there is an abundant amount of). The research shows that SMS can be used in varying conditions that could benefit multiple agricultural centers and farmers who wish to used a less harmful alternative.
