I use general hydroponics “pure spray” instead of been oil. It is just mineral oil. You don’t have to wash it off. It kills bugs and you won’t be smoking neem oil which can cause toxicity.

Lost coast plant therapy

I agree with this. I have used plant therapy many times for different reasons and always tends to work for me. I use it 3-5 days straight when my lights are off and then twice a week for maintenance. If I am dealing with spider mites I switch it to a different insecticide as they tend to get immune to certain things.

Oh no sorry that is for veg stage. I don’t spray anything on it during flower. If you have a big infestation during flower you probably have to bug bomb it. Like dr. Doom

You can use the other stuff I listed during flower - https://www.amazon.com/dp/B07M983TRL/ref=twister_B09R2CP56Y?_encoding=UTF8&psc=1

However, I would not use it once I pass the 3 week mark from harvest, it may effect the flavor of your buds (you can rinse it off before you chop too) It just has a slight vegetable oil smell to it as that's mostly what it is.

But usually during flower I simply use a hose or sprayer with a decent amount of pressure, and blast the buds and leaves. (if you have bugs). If you kept up on preventative measures in Veg, you should have less or no problems in flower. But if you do, first I always suggest spraying with water, and massaging the buds, leaves and branches as you spray to knock off as many bugs and eggs as possible. You can use quite a bit of pressure, the plants can handle it.

But yeah that AgroMagen stuff is hands down the best I've ever used and worth every penny. I've cured several growers' crops from spider mite infestations- guys that were spraying AzaMax and even Eagle 20 (NEVER USE THAT SHIT ON CANNABIS) and still couldn't get rid of their spider mites - 2 or 3 sprays of that stuff and you'll never see them again

Plant therapy states that you can use their product up until harvest day. Personally I haven't done it myself, but if they have it on their website I am sure it has to be legit or they will have a lot of backlash.

I really need to put my "Ultimate Neem Oil Guide" to paper and get it out of my head ...

Ok here goes.

First of all there are different types (brands) of Neem oil. I personally recommend "Garden Safe" brand "Neem Oil Extract" as it does NOT have the active ingredient azadirachtin that most other neem oils have, that can controversially end up in your end product, even if sprayed only in Veg.

First, this brand is readily available, easy to find at Walmart, Home Depot or Lowes.. Second, it's cheap. 3rd, it works, if you know what you're doing..

Number 1 rule of neem oil is NEVER EVER spray neem oil during the day or during lights on period. You MUST spray either at Dusk (outdoors) or JUST before lights out (indoor) to avoid "Neem Burn" - a condition caused by a reaction of the light and neem oil that will literally turn your leaves into crispy critters. So you need to allow time for the mixture to dry on the plant before the sun/light hits it.

Follow the recommended ratio on the bottle (Found under the label, in the "miticide" section) - should be approximately 2 to 4 tablespoons per gallon. For preventative measures I go 2 tbsp. - for extreme infestations go full strength 4 tbsp. per gallon. NEVER EVER more than that or you'll burn your plants.

Next, use WARM water (approximately 80-100 degrees) and make sure you constantly shake your sprayer as you are spraying to keep it mixed. Oil and water don't mix well.

Also use a wetting agent (coco-wet for instance) or this stuff - https://www.thcfarmer.com/threads/in-search-of-cheaper-wetting-agents.141158/

Another rule - never spray neem in Flower!

Tip - If infestation of spider mites exists, make sure you spray the under side of leaves (as this is where they like to live and lay eggs), and gently massage the leaves and branches with your empty hand as you spray (helps knock off eggs and bugs)

Tip - spray once every 3 days if infestation exists - or once every other week for preventative.


I've been using this stuff for YEARS and if you follow these simple rules/tips you'll have no problems.

Personally, I stay away from any other brand neem oil especially the garbage made by Dyna-Gro.

If you have the money to spend, though, I HIGHLY recommend THIS STUFF as an alternative to NEEM - https://www.amazon.com/Bio-Pesticide-All-Natural-Insecticide-Pesticide-Better-Insects-Non-Phytotoxic/dp/B07PH46H8K/ref=sr_1_1?crid=2JLMBYLUCVOXT&keywords=agro+magen+grow+safe+bio+pesticide&qid=1660526141&sprefix=agro+magen+grow+safe+bio+pesticid,aps,443&sr=8-1

Works WONDERS on just about every insect, AND won't kill bees!!!

This guy is SPOT ON and just saved me a lot of typing……for serious infestations spray at a min of every 7 days ….hotter temps every 4-5 as their reproduction is accelerated….but as previously stated NEVER in the light….and NEVER in flowering….!!!

If those pictures you posted are recent and they haven't developed flowers yet, just "started" flowering - you can still use the Neem. Those plants look like they're just now flipping to flower, still early enough to get away with a neem spray. Now once you hit like week 3 of flower - definitely stop neem. Switch to just blasting the plants with a water hose. It's outdoors you'll be fine.

Also 1 good preventative spray of neem before it goes into full flower isn't a bad idea - and being outdoors believe it or not you're less likely to have insect problems outdoors than indoors. Indoors tends to be harder to control because infestations have nowhere else to go. Spray that plant with neem and watch the bugs move on to other stuff that's not covered in neem.
