Pure Sativa Greenhouse

[Buddler]

What about pest strips ive heard they work well .other than that and neem oil. You ll have to desroy all infected take clones first then treat them I have had to do that to salvage a strain ,growing all those different types of plants together spells disaster if you get mites ive done it and had to start over from seed they will be all over everthing so every plant has to be treated . If you use neem every five days as least three to four treatment and a fresh water rinse in between.Good luck Bear, B...

Hey Bear...sorry to hear about your problems. I know this sounds way too simple, but one thing I tried before was spraying the underside of the leaves with hot water...

Not blazing hot, mind you...just hot. Works on scale too, if you should ever run into them with your other plants.

Good luck!

Great thread, love the Sativas and the folks who grow them

If you can seal your gh you can choke out the mites with extreme high co2 levels.

Look into high brix/nutrient dense gardening. I am just baby steps into it but so far so good. A natural way to boot plant immunity.

Thanks for sharing the GH

awesome thread, that sucks about the mites.
I bought a HVLP paint sprayer from a big box store for well under $100 it attaches to
the base unit that sounds like a vacuum cleaner with a long flexible hose and it has crazy
power and blows whatever you are spraying everywhere. I have used it with neem every
three days with good luck but if I had that trouble I'd go with the avid. there's a vendor on
amazon who repackages and sells small bottles of the expensive big ag products for $20-$30 bucks.

it looks like you have things growing in your GH that are not cannabis, might be where your mites got started.


good luck I just found your thread and I wanna see those girls bloom!

Thanks for the replies everyone.

I have read through the IPM literature and I have been spraying Azamax every three days for the last week, another spraying is due soon. I have ordered predatory mites and will release them as soon as they arrive. Is anyone familiar with the predatory beetle, ladybug variant? I forget what its called but I might release 100 of them, they are supposed to eat 40 mites/eggs a day.

I know I mentioned it before- research "lace wings". one thing with predatory mites, if you are spraying for mites, you may well be killing your predator mites :/

 

[McKush]

Keep on truckin' Bear. best of luck getting rid of the little bastards.

 

[wildgrow]

Hayzeus, bear! Hope you get those mites under control. Id hate to see you have to dump '72 again.

Whatever predatory insect youre gonna release - up the number x5 or even x10.

Frost Monster is insane! Budsites galore!

How about an update?

The mites really have me down. Im not going to waste everyones time complaining about them, it is what it is, but here are the facts of the case because they might help others:

a) The infestation began and became apparent when the plants were already to large to be treated properly using sprays. Look at the frost monster in the pics below, its just not gonna happen.

b) even though it was my intention to create a 'jungle', that was stupid. Now the plants are almost all touching, making nice little bridges from one to the next.

c) there are some functional things to avoid when growing sativas or anything in a greenhouse: Gravel floors suck ass, they can't be cleaned. Thats poor cleanliness right off the block with not much you can do about it. If you are growing indoors/greenhouse, its a recipe for disaster to have plants shaped/sized in such a way that you can't access parts of them (e.g. the Diesel, the middle third can't be reached and you can't get in past the screen). You can see that ladder in the background BUT its pretty tough to set it up without beating the plants up.

d) predatory mites, at least the ones I got off of amazon, are...eh...pffff. No change. Maybe its too hot, maybe not humid enough, maybe something else.

e) azamax works but requires dilligent application to ALL parts and soil surface, and as I said above, no way in this greenhouse.

f) pyrethrins work like a charm, the first and maybe the second application. They get 99% of the mites. The 1% will repopulate. After that, you're dealing with generations of mites spawned from resistant ancestors. At this point spraying things like Dr. Doom is killing beneficial bugs and the mites are laughing at you.

LIVE AND LEARN.

hi BR, sorry to ear your mites problem!

just want to say that predatory mites can't be release just few days after spraying stuff like Azamax! you're just killing them as soon as they come to your garden before any battle against the real bastards mites!!! had myself long fight against them, know your pain washing big plants in veg... but must say during flowering with short day time, mites move on top of the plants & are real harder to fight for many reasons...
predatory mites can just slow & down the emergency but hard to solve the problem totaly!

read some good books like "Hemp Diseases and Pests: Management and Biological Control" from J.M. McPartland, D.P. Watson & R.C. Clarke. it can be real helpfull in your case to know your enemy better & mash it up!

good luck wish you the best!!!!

Greatly recommend checking out "Roots; Demystified" by Robert Kourik.
Awesome resource, especially with inter-planting and thinking about root systems.
Love Living It,

Thanks! I agree about the azamax having a negative effect on the predators. I released roughly 6000 mites, but probably closer to half that were alive in the containers that I received. So my thinking was that if I released them four days after spraying and washed the plants beforehand, at least some of them would take up residence in the thicker foliage spots, enough to establish a population. When I came back from a four day trip last Monday, I didn't see a single predator mite and the Diesel was chewed up at what looked like twice the level of beforehand.

I sprayed the Diesel with Azamax again because I could see many two-spotted mites and no predators were visible anywhere. My thinking this time was that, since I couldn't spray/reach about 35% of the plant, any predators in this portion would live and continue to reproduce if the conditions were right and if they were actually there.

If the problem from Azaractins is actually arising from predators eating mites that have eaten the compound, if it is persisting through the food chain, then that blows my thinking out of the water. This may be the case.

I will wait a few days before releasing the next predator, a larger and more visible ladybug species called Stethorus Punctipes. In my experience these types of creatures flee the scene, but there IS ample food inside and outside can only be hotter and less humid, maybe they will turn around when they reach the vents

 

[recent guest]

Is there any living WITH them? I feel like I kooked out/went bananas about a month ago over this, and honestly the situation has pretty much remained stagnant through a period that should be about 4 mite generations, maybe gotten a little worse on the diesel. Could I keep knocking them back where I can and maybe have a stable population and still harvest some good buds? Because there is likely no getting rid of them, at least not for this grow.

spray a mineral rich nutrition dose. You want your plants as healthy as possible. Everytime you spray a cide, you are weakening the entire plant health system. imho

 

[wildgrow]

Hate to say it, but I think at best you can slowly lose this war against the spider mites :/ I don't think 10,000 each of 3 predators are going to help at this point. I wish the reality of the situation wasn't so discouraging.
Im definitely not saying give up. You may have to cull and/or cut back branches to separate the plants - remove whole branches so that sprays can penetrate deeper into the foliage.

Now is the time to plan for pest control on the next round. Like how youre going to sterilize the greenhouse, mitigating pest introduction (Good chance they got in on your clothing or on plants brought in later.), etc.
I know your hesitant towards chemical use, but treating the outside foundation and sill with pesticides will help keep them out that way. Eliminating all plants within 4-5 feet of the foundation could help. And the cats - they could be carrying pests in on their fur. Filtering your intake. You could even go as far as installing an outdoor shower - strip, bathe and garden in the buff.

That's my vote, strip naked and put on a full face breathing mask with a tank and regulator....

The view from your neighbor's of you walking out / in will be priceless... Heisenberg style

Hey there BR, amazing, simply put I envy you. Mites or no mites nice grow and greenhouse! Good luck n grow on

Hey folks, thanks for the replies here. Unfortunately, I had to go away for a couple of weeks at the beginning of september, and when I returned, the mites had decimated the Frost Monster and the Diesel beyond the possibility of recovery. It was a crushing sight to see them so yellowed and depleted. Both hazes had suffered a degree of stress, and the mites had taken up residence there too. Thankfully, the Panama and GD-72 are both VERY strong plants. They have some mite damage and it is clear that there is a presence, but overall they have maintained their lush greenery and are starting to flower. The GD has its first pistils and the panama is building small nuggets everywhere.

At seeing such a primordial horde of mites I removed all the plants that were visibly infected with them, and kept the Panama and GD. Unfortunately, there is no food left in the greenhouse for whatever thousands of borg that were displaced with the removal of the rest of the plant matter. Their next targets will inevitably be the two remaining plants. This has already been a crushing defeat. Its a race to the finish now for the survivors and I dont have any idea how long the GD will flower for. Based on the fact that lots of people have already harvested outdoor indicas and she is only just shooting pistils...i imagine its a while.
