Karen from Mission writes,

Can I use this on Marijuana mothers to combat spider mites?

If yes, how much do I need to order to effectively cover 10 mothers that are 44" tall and 26" in diameter? Also, do you ship to Canada?


The Koppert Swirski-Mite Plus are labeled for use in and on greenhouses, field salad and ornamental crops. We would recommend contacting the manufacturer directly at +1 416 291 0040 for more information on if this product can be used on marijuana.

We can only ship within the US.
