I had feed them the day before. But after seeing how droopy they were I gave each of them 5 cups of water with fasilitor and super thrive to hopefully help deal with the stress as soon as the heat cycle was done.
Keeping fingers crossed!!!!!
You are going too high with the temps. 120 F for one hour should be sufficient. Don't go over 120. Not necessary and at some point can be too hot. You would droop too @125 for an hour. I have seen hot water dip temperature recommendations anywhere from 111 to 118 F. So 120 is plenty. No reason to go over that. 118 probably sufficient. Don't cook your plants for three or four hours @ varying temperatures.
My temps were like that from trying to get the room to temp, not intentional.
Unfortunately, I've seen a few more crawlers while scoping.
I wonder if humidity and temp plays any role - my humidity was pretty high through the process....
A crawler? Makes me think root aphids. Can you post pictures of your plants, please. You have to upload them to your gallery first. Then click (double click) on picture, and copy the box that has "BBS" code. Then paste that into your post and pictures will be there. Limit 5 per post. A picture speaks a thousand words. Are you seeing eggs on the underside of leaves? If so, are they shriveled up? Do you have a yard where these could also be present, and could possibly be re-entering? What kind of scope are you using? Does it have a USB camera? That would be nice.
I mean I saw one of the Borg sucking on my flower!
On the road to finding out I had BM, I scoped my media from several pots. Nothing - no root aphids, no larvae, nothing moving. My roots look awesome considering how horrible the leaves do.
I'm certain I have BM, I have seen the eggs plain as day, with the little spots on them. I've seen the mites too, in my newly forming flowers. I've already traced it back to the source.
I will get some pics up, thanks for the info on how to do it. I took some right before the heat treatment, and again last night.

Nice. So they perked up? They look better. I should have mentioned, sometimes there will be one or two plants that the mites gang up on and they will look worse than the others. These should be tossed. But maybe you already did that. What about eggs? Are you seeing any? If you are still seeing live mites, you will have to repeat the process in a couple of days, but don't go over 120. They are probably elsewhere in your house/yard/HVAC ducting, so they will come back. Just be aware of that, and keep the aspirin going. These things always come back, so be prepared.

Just curious: What was the source? Clones?
PO - both directly and indirectly as I traded some cuts with another patient who also sourced from there. We've now determined he has them too. Go figure, in the end, I never even kept any of those genetics. Although placed in quarantine, scoped, dipped and sprayed - these little bastards made it past QC somehow.
I'm working on an ongoing biological program - bacterial teas - to control their numbers.
I have a yard, roses, etc. I can only expect due to their size that I may have a while before fully eradicated. I shower before working in my room, but like you said, they are probably everywhere.
Predator mites help, but heat will kill them too. Neosilious Californicus will work, but you need tremendous numbers, and they are costly. Really, heat is the best method, & I've tried them all.
Yeah, they can get on your clothes & shoes, etc. It's a tough problem. I sterilized my room, left it empty for 6 months, sterilized again, and they still came back. And I live in the city.
I had my only successful run in a year last run. I am positive it was because I was brewing tea containing the above fungi, I religiously used the stuff because I wanted to see if it made a difference. I used both foliar and drench application methods.
I ran out of it and didn't use it this veg, I had only given one application a couple days before I realized I had BM. I feel confident I can manage populations using it. It has to be what made the difference.....
Plants look even better tonight....

How far into flower can you do the heat treatment?
I recently got a replacement for a broken microscope, a usb endoscope with record capabilities.
So i found 2-3 weeks after the first heat treatment they have just started to come back. So i cut off a bunch of sample infested leaves/tips, and shot video of them at close to 500x.
Then i set the space up with multiple thermometers as i had a hunch the heat was not homogenous in there. I tied thermometers to plant stems at different heights, some right in the middle canopy, some top and some bottom. I then heated the space up and found upto a 5-10 degrees C difference within the space. It was much cooler lower and right in the midlle of the bush near the meri stem(plants natural cooling system). Essentialy i found cool spots in the 50C 120f heat i had in the space. I got the air moving around in the space by adding more space heaters set on just fan and no heat( they are a fan that wont burn out at that temp), blowing the 120f heat around the space and through the cool spots.
Kept that up for an hour and cooled the space and plants and another hour later took leave and tip samples. All adults dead, have not found a single live one and i took videos of the dead mite bodies. I really cant say about the eggs but i can say for sure nymphs and adults die.
I will find a way to cut stills out of the videos and post em.
I also still have a bunch of infected leaves and tips in a sealed container i will be running some before and after pics as i do some experiements on what safely kills them and what doesnt.
Much respect

I have done the heat treatment upto 4-5 weeks into flower. One thing to remember is smell and your safety. i found i had to turn the fans the suck the air through my carbon scrubbers off to achieve 120f. ANd when i heated the space the plants gave off triple stink, terpenes do evaporate off the plants at those temps, and having no scrubbers running and massive positive pressure i found the space spewed out sweet sweet herb smell very very much, it really stank the place out for the time it was happening . Be security concience when you do it into flower and know it will stink unless you can put them in a tent in a room and carbon scrub the room.
Other than that i noticed no pistal burning or loss and there doesnt seem to be an adverse effect, am close to harvesting some that have been heat treated and they are their normal lovely selves.
Just dont go over 120f, if you go over 120f you risk damage and there is no need to. Also 1 hour seems to be plenty.
Much respect and ty to retro again for the idea
