Organic Cannabis Pest Control
Like any other plant you grow in your garden, Cannabis is attacked at different times by various bugs. Some of these bugs (like aphids) aren't too serious and are easily remedied. Others, like the dreaded Tobacco Budworm, are a huge pain in the arse and can seriously hurt your crop. Consider your plants' health in a human context: If you are run down, scraped up, eating poorly and constantly being stressed, you're more likely to get sick than if you are fully fed, well-rested, and having a good laugh every day. Likewise, even chump-change pests like aphids will have an affect on your plants' overall health and make your plant more susceptible to things like powdery mildew, botrytis and the dreaded fusarium wilt. So do your best to make sure that no pests go ignored.
Now, let me introduce you to the pests I've encountered here in Southern California and what organic solutions I've used to keep them in check. I'll also show you the good predatory bugs I've found so you'll know to let them be...they're fighting the good fight!

How to Spray Cannabis for Bugs - A few very important things to remember
When you're spraying your cannabis for pests you need to remember a few very, very important items. Not following these guidelines can spell trouble for you down the road and we don't want that. Did I mention these were important?
Once you've got a few summertime grows under your belt you'll be able to flex within these rules. But right now you're growing cannabis for the first time and my job is to get you to the finish line so please do your best to follow them.
- Do not spray your plants with anything, including plain water, in the late afternoon, dusk, or evening hours.
- Do not spray your plants when bees are active in your garden.
- Do not spray your plants in direct sunlight.
- If your plants have buds, avoid spraying them on very humid days

Recommended Organic Sprays for Cannabis Pests
This information is already contained in the Cannabis Pest subsection but I'll put it here as well for reference.
Neem Oil - Essential
For 2-3 plants, mix this into a quart spray bottle and hit the entire plant, including the branches and trunk. Begin spraying when your plant is about 2-3 weeks old (once it's strong enough to hold water on top of its leaves). Continue spraying weekly until buds begin to grow. Don't get Neem Oil spray on your buds as it could make them smell and taste like Neem.
Monterey Garden BT Spray - Essential
I use this regularly once buds start growing. Use once a week to keep the budworms at bay. A quart spray bottle will cover 2-3 plants.
Monterey Garden Insect Spray w/ Spinosad - Optional
A good all-around spray but Spinosad harms bees so I only use this if I see Thrips, Aphids or Leafhoppers beginning to colonize my plant. Still, this is good to have on hand just in case.
Azamax - Optional
I use this only if I encounter Spider Mites. Mix a half-teaspoon into a quart spray bottle and spray weekly.
Neem Oil - Essential
