not to sure actually...

silica is non toxic to humans (it's only a choking hazard)

find out for sure or try it with a small portion of your harvest.. never attempt a new method with your entire crop.
BobBong Reviewed by BobBong on . DRYING bud with SILICA sand???? has anyone heard of silica sand? or has anyone used it? it is cheap and can get it at hardware stores for cheap and it is used to dry oil spills on pavement or lots of growers use them to dry their flowers so they can save the flowers as decoration. i was thinking if you put the buds in this silica sand, it may help the process of drying it and there would be no heat to dry it too fast that way. so not sure if this process would cause harsh smoke or not. i may have to try this method Rating: 5
