Stone Rockwool TP36 seedling starter plug
The Stone Rockwool TP36 Plugs are superior to other typical hydroponic supplies, lightweight, with up to 96% porosity and 91% water, does not absorb nutrients from the crop, good water absorption and strong air permeability, which is the best substrate material for soilless cultivation.
These 1.5 inch rock wool cubes can hold their shapes well without falling apart, keep the seeds long enough to establish a root system because of their high water absorption while retain a lot of oxygen, so that the survival rate of transplanting is high.
They provide ample space for root system expansion—supporting robust early root development—and delivers exceptional performance in both practicality and results. These advantages make TP36 the most popular clone plug choice for cannabis growers, ensuring a reliable foundation for healthy, vigorous plant growth from the start.
