Seeds Pests and diseases
The spider mites, usually no more than half a millimeter in size, do not have their name wrongly, as they are related to the spiders and they belong to the mites. The two most common spider mite species found in cannabis cultivation are the common spider mite and the fruit tree spider mite, also known as the red spider.
Spider mites are sucking pests that deprive cannabis plants of their juice and thus their energy. This leads to impaired growth. Spider mites are mostly concentrated on leaves. Larger populations weave fine and firm nets. They can also transmit other plant diseases.
The first signs of spider mites, which usually move on the underside of the leaves, are bright spots on the leaves. Spider mites usually attack the leaves in the lower area first. Their colors can vary, but they are easily distinguished from other troublemakers by their eight legs. Their networks can also help identify them.
A very effective and popular oil against spider mites is neem oil, which can also be used against other sucking pests. When growing cannabis indoors, all air openings can be fitted with fine filters. It also helps to wear different clothing in the grow room than outside. In addition to the hemp plants, you could also create a place for insectivores, for example tall grass.
The earlier you discover spider mites, the better it is for the marijuana. Your own biological agent can be made with cinnamon and cloves. If possible, you should increase the humidity in the grow room. You can use the natural enemies of the spider mites, such as ladybugs, lacewings or the predatory mite. If you want to rely on organic products, those from Neudorff are again recommended. In the event of the most catastrophic infestation, the only thing left is advice in the specialist shop regarding the choice of chemical club.
