If you notice that the leaves of your cannabis plant have some small brown or black spots on them, or perhaps a trail that looks a little snail-like – then, unfortunately, some pesky thrips have decided to make your plants their home. These can be seriously damaging to your plants but, worry not, they can easily be eradicated thanks to this Pyrethrin Concentrate from PyGanic Gardening.
Pyrethrin is a natural insecticide that comes from Chrysanthemum flowers – so entirely natural. This extract is poisonous to insects as it shuts down their nervous system resulting in their death. This is a very popular natural alternative among cannabis growers. A real pro of this product is that it can be used at all stages of your plants’ growth – up until the harvest, a con, however, is that you really need to make sure you get your dosages right as it can damage your plant if you use too much concentrate.
