The spider mite is the most common pest found on indoor marijuana plantsand causes the most problems. To a new growers, they are hard to spot, spider mites have eight legs. Find microscopic spider mites on the bottom of the leaves. However, their telltale signs of feeding, yellowish white spots, on the tops of leaves are easy to see. Careful inspection reveals tiny spider webs on stems and under leaves as the infection progess’s. A maginifying glass will help you see the yellow white two spotted, brown or red mites and their clear eggs. Indoors the most common is the two spotted spider mite. After the they fuck like rabbits females are fertilized for life and reproduce 80% female and 20% male eggs, females will lay about 100 eggs. (poor bitch)


Spider mites suck life giving sap from marijuana plantscausing over loss and stunting of growth. Leaves are poked with suck hole marks in yellow from failed to produce chloraphyl. The marijuana plant will loose partial to full function (which means your marijuana plantsare fucked) Leaf yellowing and drop. Once a plant is overrun with spider mites the infestation pregresses rapidly.

In simple words if you get mites and don’t catch them you are screwed.

The tobacco and pepper soap solution works well and should be used daily, spraying on the underside and top leaves and later the whole plant. Since spider mites are very residual to common products, you have to find or try any number of ones untill you get rid of them. make absolutly sure you retreat as stated, other wise you will get resistant spidermites and then you have a bigger battle on your hands.Also do not allow pets that go outside alot to be around indoor plants,mites have been known to be carried in from pets to plants. PLEASE NOTE, below are ways to get rid of spider mites, but no 2 mite infestations are identical, you almost always have to use different products to get rid of them, also make a habit to check for at least a whole month after thinking you got rid of them, that way your chances of the spider mites that became resistant breeding and then having a bigger problem.
