In Veg only. Cannabis is a hyper/dynamic accumulator and the Hot-Shot no-pest strips are toxic to mammals as well as mites.
Explain how the plant absorbs dichlorvos from the air, dingbat.
Ah yeah, you blocked me and half the rest of the forum.

would flowering under 13 hours of light help the persis survive longer?Tetranychus urticae, The two spotted spider mite is a common problem with Cannabis.
An often used control is Phytoseiulus persimilis (predatory mite).
It is commonly known that the two spotted spider mites prefer higher temperatures with lower humidity, while the controls prefer and reproduce better at lower temperatures and higher humidity.
I recently did an experiment with 4 small identical HK clones in my window, they had gotten mites from my wife's misc house plants in the same window, so I bought 1000 Phytoseiulus persimilis and dosed all 4 HK plants equally in Oct. After a few weeks 2 of the plants were all cleared up while the other two still had problems. The only difference was the two cleared up ones were under lights each night to keep them veg, the other two were under natural short photoperiod, and flowering and the Phytoseiulus persimilis while not going into full diapause do stop hunting for the most part.
Lesson, use Phytoseiulus persimilis in veg cycle because they are not very effective under short hours used for flowering.
And use predators that are not negatively effected by short photo periods during flowering.
Like most below:
Feltiella acarisuga (Therodiplosis persicae) A cecidomyiid gall midge.
Stethorus species Three species of tiny ladybeetles (S. punctillum, S. punctum, S. picipes)
Macrolophus pygmaeus (predatory bug)
Dicyphus hesperus is an omnivorous generalist predator that can help control mites.
Orius insidiosus, also called the minute pirate bug, a generalist predator, Orius feeds on many pest species, such as mites, aphids and moth eggs for food.

So, that's not true?
Are they effective and/or safe to use?
The loud and obnoxious one is actually one of the 5 (yep, there are 10 people on icmag and I'm blocking half) garbage dumpers I prefer not to read.So, that's not true?
Are they effective and/or safe to use?
I do not and will not use pesticides to control spider mites on any plant to be flowered.
If people use poisons they should dip instead of spray very very small 6" or less veg plants.
Then grow the plants very large veg and make clones, grow and flower off the new clones.
You do need to maintain clones mite free. But it can be done by being careful, and using prevention like predators to avoid any real problems. It is much easier to prevent mites with predators then to cure a mite problem with predators. It is easy to control a mite problem with predators but almost impossible to eliminate them 100% with predators.

The "corn cob" stuff is vermiculite. Just FYI
Now that you mention it, cannabis sucks up everything else so it wouldn't surprise me there's some mechanism of capture it can use to taint itself.
Corn cob grit. Confirmed with the entomologist at my supplier.
No big deal, that was a cool idea about the envelopes.Cool, thanks for the correction.
