Another common herbivore are thrips. They are small, fast-moving insects with wings. They rasp, or grate the cannabis leaves open, and then suck the sap out. Thrips prefer bloom tops, and fresh, young cannabis leaves. Affected cannabis leaves have shiny, silvery spots. This is caused by the thrips, which suck the chlorophyll out of the cannabis leaves. In spite of the fact that they're small, you can see thrips marching in columns on an infested plant. Thrips can be fought with insecticide. It's more environmentally friendly however to unleash the thrips' natural enemy, the predator Amblyseius cucumeris. Lice are found inside as well as outside. During the summer, when lice do the best outside, they also do as well inside. Lice are the most interested in plants with questionable health. There are two methods to kill lice, spraying with insecticide, and setting out assassinator wasps. The problem with most flying pest- destroyers is that they're attracted by the high-pressure gas lamps, which draw them to a fiery death.

The starting point for cultivating cannabis is successful climate control. This goes two ways, the plants do well and produce the greatest possible yield, and diseases and pests get the least possible chance. So, create a good climate, and don't forget hygiene If you're bothered by diseases and/or insects, preferably use natural methods of control rather than chemical remedies. You can fight your pests by releasing their natural enemies, or by spraying with organic solutions for diseases and/or pests. Use chemical pesticides only if nothing else works. Always stop using pesticides a few weeks before harvest, otherwise, you'll be smoking some of the poison later. Ultimately, fighting diseases and pests works best only if you know how to optimally control the climate at the same time. Along with climate control, the prevention (and if necessary, curing) of deficiency disease demands an optimal mixture of fertilizers, and the control of the pH hope this helps you all, the postman.

This damage looks alot like nutrient burn, except it occurs only at the tops of the plants closest to the lamps. There's only one cure for this...get the heat away from the plants, either by moving the lamps or moving the plants Rating: 5
