I use Capt Jacks as well, but the important part for fighting spider mites with Spinosad is you must use a wetting agent with it.... I use fox farm's sledgehammer as a wetting agent...
Add the wetting agent first, mix, then add the Spinosad... I usually mix a half gal at a time... A teaspoon or splash of sledgehammer and, 2 tablespoons capt jacks.. I call it The Captain's Sledge ... I also use Azatrol as an alternate... but only for veg or plants just put in to flower...
I use a pump sprayer set to spray a fine wide mist... start at the top and work my way down carefully covering the top and bottom side of all the foliage.. wear long sleeves and a mask.... use everything you mix on your plants, and never dump Spinosad down the drain.

Per 1 gallon of water:
1 oz. neem oil
1- 1/4" to 3/8" diameter rock of agsil16 ground into the water
2 ml lavender oil
2 ml thyme oil
2 ml eucalyptus oil
2 ml rosemary oil
In Veg and up to 2 weeks of flower add 1 oz. of dr bronner's soap.
Shake the fuck out of it while spraying.

This works plain and simple. Spray the undersides, and the tops of leaves. If you have an infestation spray every 3 days 4 times. Then spray once per week. If you don't want spider mites spray once per week until two weeks before harvest.

Before you know-it-all fuck boys start talking shit about spraying flowers, learn how fast neem, and essential oils breakdown on the leaf surface when the proper microbes are present.

FYI Spray until 2 weeks before harvest.


Good luck, and if all else fails flame throwers work every time.

Dawn (and some other brands') dish soap will make insectidal soap just as well as Dr. Bronner's, just make sure it's not one of the detergent varieties.. 2 Tbsp Dawn and 2 Tbsp vegetable oil per gallon of water will make an effective spray or dunk. Cut it in half if they show burning. Dunking a plant in the soap mixture will usually require a pretty thorough wash & rinsing until the plant stops spitting out bubbles, but most plants can handle a full dunk without complain.

Heat also kills mites, and is relatively free and available. A hot water dunk of about 110-120 degrees (you need an accurate cooking/candy thermometer for this), for 15 minutes, will wipe out most if not all of your mites, as will bringing up your grow room to those same temperatures for a half-hour or so. Sensitive plants may not take kindly to the heat, so it can be a bit of a risk...but so are most of the other treatments when you reach infestation level.

You can combine both of the above into a hot water soap dunk, for a relatively cheap, available and effective way to combat a mite infestation.

I think an important thing that pot growers overlook that is a common term in mainstream horticulture is "allowable threshold". Spraying neem every three days during a battle, and once a week as maintenance will kill 99% of your problem, switch to something like hot pepper or nicotine spray late in flower. There might be one or 2 banging around on some lower leaves but this will in no way effect final product in an substantial way. Laughing at people who throw away whole crops or drop hundreds on avid. If you feel things are so bad that you need heavy artillery, hot shot strips are 10 bucks and knock those fuckers out quick

Spider

If you have time and patient you can use chopstiks and honey.
Put the honey in the chopstick and roll it by the underside of the leaf.

You need to spray the poor girls you got those mites from. Makes me cringe to see that

Bronners soap is at London drugs in Canada now days I think.... Should be an easy find.

Wintergreen oil from the drug store works well n goes a long way...

Yes, you can have spidermites and they wont affect your plants or yield that much.

It's only when the population explodes for some reason that they can kill your plants.

Defoliating during flower can keep their numbers down, as they are mainly on the fan leaves, and if you are pulling off the fan leaves that have lots of eggs and mites on them then it can help to prevent an epidemic happening.

But best to spray in veg, maybe twice, once when they are small and then just before putting into flower.

The downside in not eradicating them completely is they can build up a resistance to the chemical you are using to get rid of them.
And then you might find that chemical does not have much effect on them in the future.

Apparently in the US there is a strain of spidermite that has evolved to feed on cannabis specifically, and has a resistance to chemicals used get rid of them.
Apparently they are hard to get rid of.

I use Yates Mavrik, contains Tau-Fluvalinate, seems to work ok.
