The Story
This research kit provides small-scale farmers, growers, and plant enthusiasts with a reliable tool for exploring flower development and bloom control. It contains two high-purity components - Silver Nitrate (Part A, powder) and Sodium Thiosulphate (Part B, solution) - which are freshly mixed to yield 250ml of active Silver Thiosulphate (STS) solution. STS is a well-established compound in plant research used to temporarily block ethylene, the natural plant hormone that controls flowering, ripening, and stress responses.
