How Late into flowering do you spray with soaps?

Had a pretty bad mite problem, got those fuckers somewhat under control with the help of Pyrethrum... today I found one plant absolutely loaded with mites... webs and all. I have gotten pretty decent at detecting those sick bastards, and the problem doesn't appear to have spread to any other plants.

I segregated the single plant, and took all the mites off with a Q-Tip (quite annoying) but I am guessing some of the mites have travelled to other plants. I am a few days short of five weeks flowering, and I'm not sure weather or not to spray em. I have buddies who say they use the sprays until a week before harvest, while others tell me to not use it once the buds are a solid "thumb" thick. I am growing purps, and like many stories I have heard of this strain, it has been a damn slow starter. I think I could get away with another week of spraying however I don't want to raise the mold risks if possible.

Found another plant that had the bugs on em... gave em both a spray. Hopefully they dont mold up... I doubt they will - I did it quite lightly. Can anyone comment how late they spray? Am I pushing it spraying at 5 weeks?

They have mosquito dunks which are high in bacillus thuringensis. They will help with the mites. You can use pyrithium. I would spray them down in the shower to wash the webs off. Mix neem in with the soap and spray the soil as this is where they mate. The pyrithium can burn so dilute it. They breed faster in over 80 degree heat with heigh humidity. if you got a dehumidifier that would help.

Yep, I use the d\h when the lights are off for sure.... I just grabbed the webs off the plants and tried to dry em a tad.

Raise the lights way up if they are wet. The bulbs explode if you get water on them so be careful.

I have the glass covering all my bulbs so I should be fine, I also sprayed away from the lights as a precautionary measure.

Good to hear. Diatanatous earth that is used in pool filters is fossils harvested from lake beds. Mites have exoskeletons and when they crawl across this on the top of the soil they slice their bellies and dehydrate in 24 hours. I would get some predator mites stat to rid your place of the beasts as this is the only way.

Yeah, I am going to grab some lady bugs...I was trying to avoid it if at all possible because it seemed like the land lord was going to be making a visit to the house and I didn't want lady bugs all over the house. But, now it seems as if she isnt coming down, and then again I should be able to keep most of the bugs in the room with a little door stopper or somethin.

I came home to my vt place one day which was painted white and had about 5000 lady bugs covering the place. It was so cool. They like flying into the light. It may be a bit mean though you can spray them with soda so they cant fly and stay on the plants if you dont have a door to your grow room or glass over your bulb.

I would go preditor mites myself

OK- BT is NOT effective against mites. Their digestive tract DOES NOT depend upon an alkaline reaction.

Spider mites DO NOT breed in the media. You've never noticed all the eggs all over the underside of the leaves? Neeming the media is useless against mites. Ya might as well go and neem your television.

Spider mites breed SLOWER in higher humidity- running a dehumidifier just makes it worse.

DE on your media IS NOT effective against spider mites, as they will never touch it.

I'd feel comfy spraying pyrethroids @ 5 weeks. If you're worried about mold, grab a bottle of Serenade or other organic anti-fungal from your local.

Neem is fairly effective, when sprayed ON THE UNDERSIDE OF THE LEAF.

Beneficials are great, but it's kinda late in the cycle to start em.

A methiocarb fogger will do it, but you're getting close to harvest- I hate smoking that shit.

Myself, I like a shot of abamectin as they move into flower- but that point's past.

Many swear by " No Pest Strips" which contain dichlorvos- never tried em myself.

Dropping your temps and raising RH will slow em down, maybe enough to get the infested stuff harvested.

Mandala- Nothing personal, but a lot of what you're saying is just wrong. I don't know how else to put it.

Well I would say the same about your posts. Perhaps we should back up what we say with webpages?

They like the soil as the dark color makes it warmer.

Mr. Penny is the smartest grower I have ever conversed with. Great store in Northern VT in Jethro

Bacillus lupis perhaps?

OK, you're up...

If the mites are feeding off of the mold perhaps bacillus subtillis.

now how about indoor controlled indoor crops. Corn strawberries and cotton are not indoor crops my friend.

http://www.entomology.umn.edu/cues/W...iallyAvail.pdf is a good resource for many pests.

Besides the isomer concentration of the corn leave would make it a hard target for spider mites.

Spider mites don't eat mold.

Mites


At this point you're just making stuff up, right?

Isomers basically are highest in waxy leaves. Carbon concentration is basic terms.

I am speaking from experience my friend that is all. I have taken on spider mites before and won while continueing to grow thousands of cannabis plants in the house afterwards. Never grew corn.

Isomers of what?

Do you even know what an isomer is?

Isomer - Wikipedia, the free encyclopedia

Folks, go check his referance...

'Nuff said.

isomers are called by some hydrocarbons. Simple hydrocarbons such as methane contain about 7 carbons where isomers have above 28 carbons. 31 carbons is the highest or most stable regarding hydrocarbons.

I am only looking to tell people what works. Dont want to fight my friend you obviously got some facts in your head. Knowledge is always appreciated.

o the half lifes of isomers is shorter then say methane as they still have there balance.

o the half lifes of isomers is shorter then say methane as they still have there balance. This is why they are not carcinogens

rhizome - I am very interested in your alkali comment if you dont mind my friend. I mentioned this as I tryed dunks a couple months back when I had some mites on non cannabis plants in my bed room. They are gone now or so it seems. I would love to learn if you are willing to teach. My experience with humidity is not as you say though it is only my experience.

Got to sleep now though perhaps we can continue this discussion at a later time. Enjoy the site.

maybe what I thought were mites were really crabs and they liked the plants better as I may smell?

I should throw some No Pest Strips in there for sure, good call. I have heard decent things about em for sure. As for harvesting them way early, I don't think they are to the point where they need to be chopped immediately.. but at what risk do you leave the plants in there... at what point do you just say fuck it and chop and know the others wont be subjected to the mites, though it really seems the spreading has been pretty damn small so far.

I am thinking I'll drop a Pyrethrum bomb in there, it worked pretty effectively last time, as alot were infected prior and it cleared most of it up until a few days ago. Keep y'all posted.

As for relative humidity levels... I'm not going to raise my r\h and put the whole room at risk when I see a few plants infected with mites...it's just not worth it. I think it's important to weigh everything with a cost benefit analysis, and my cost is way too high to roll the dice like that.

Oh HOLY crap HAHAHAHAHAHAHA I think KArmaxul has just snuck back in!
I KNEW I smelled a pile of gorilla dung!

Dude, don't start on this isomer crap. An isomer of WHAT has a half-life shorter than methane? WHATTHEFUCK. Methane simply doesn't HAVE a half-life, as it is QUITE stable. So... a half-life shorter than that of something that does not even have one?

If you are NOT Karmaxul, please say so. And be warned that HIS grasp of chemistry is more mystic than scientific... I look at the Gorilla Grow line of products with a GREAT amount of skepticism... well, and it didn;t help that I've seen pictures of the dude's plants... I've seen better plants grown by a 15 year old in his damned closet.

MAN I didn't know it was Comedy Hour on canncom.

What up Stinky Attic, good to see ya again.

So are you Karmaxul then, all TOR'd up and in-cog-neat-o?

LOL...I wish you'd reconsider! Nice nab and goodbye to ol' boy.

Have a good grow!:jointsmile:

All right P4B, you're on. Let's talk. I emailed you back.

good nose, Stinky ! :thumbsup:

I never understood much of what them there smart fellers wuz talkin bout, nohow ... i buy them No-Pest Strips down yonder up to the WallyMart, and me and the missus aint never had none of them bug critters y'all got , nope, not eeven once ... them 14 younguns of our have been scratchin at their heads a lot, tho :jointsmile:

Personally I'm a indoor grower and NEVER had probs with bugs or mold. I ALWAYS sterilize my soil before I use it.....in the oven one cookie sheet at a time at 250 degrees for 20 minutes. Kills all the lil' critters along with any nasty spores and eggs. It's a long process to get through all the soil but like I stated.......never had critters.:thumbsup:

Have a good grow!:jointsmile:

Good work! That is surely alot of work, your efforts certainly have paid off it seems. I am in my second cycle, no mites on the first one... but have been trying to battle those little fuckers this entire grow pretty much. I am almost certain the clones I got had mites on them already when I got em.
