Thrips and Marijuana

Thrips and marijuana are two things that unfortunately go together all too well. When growing marijuana it is important to know as much as you can about pests that like to invade the beautiful green leaves on cannabis plants.

Thrips and marijuana have been two words that go together for many thousands of years. Thrips are tiny little pests, about 1.5 millimeters long.

They have wings but can barely fly. They are big enough to see with the naked eye. The wind and fans help move them around since they have very little flying ability. They are usually yellow or brown in color.

Thrips like to live on the top surface of leaves. Thrips prefer the buds of flowers as their home. When growing cannabis indoors it is important to look closely at the leaves for any signs of infestation.

Thrips will pierce the leaves until sap comes out, and then suck up the sap, leaving a patchy white mark on the leaves.  Leaves will turn all white after being sucked on by thrips for a while. The leafs will then turn silver or bronze, and eventually turn brown, become dry and crumbly.

Plants will die if thrips are not controlled. Thrips like warmer climates, so they thrive in indoor gardens.  The female thrips lay anywhere up to 300 eggs at a time.  It takes about a month for the eggs to become fully matured adults.

 How To Prevent and Control Thrips on Marijuana

If you are going to grow your own marijuana it is vital to be able to recognize the signs of insects and disease on your plants. Growing cannabis indoors can be a very fruitful pastime if done with a careful eye. With a little knowledge, thrips and marijuana do not have to be two words that go together on your garden.
