I don't get anything from it. I also just kind of just do a thorough misting, instead of a drenching, when the buds fill out. And I stop about 2 weeks before the plant is done. Like Joedank pointed out with Spinosad, neem and dish soap also degrade quickly under UV light and I get plenty of rain too to wash it off. I know they both wear off pretty quickly because bugs will be on my plants like white on rice in a glass of milk on a paper plate in a snowstorm if I don't keep up on the spraying at the very least one a week.
Here's a read for you HiloReign from the EPA and there's plenty of other sources that you can look up that say the same stuff. The bottom of page 12 shows the half life of neem on a leaf surface under UV light is 2.47 days and 3-6 day in a forest environment in terrestrial matrices, whatever they mean by that, so no worries I guess even within 6 days of harvest at most.
I just stopped running Ace's Malawi after 1.5 years. It has a good effect and is really potent that gets kind of overboard after a 6 month cure. I liked it, but it wasn't a big hit with everyone. It's somewhat airy (not that that should matter, but it does with some people...... silly people). It was frosty, but didn't look that great and it smelled like parsley, celery and good dirt which I liked, but nobody was raving about it or anything. I would like to run all of Ace's and Cannabiogen's stuff though someday.
Are you running either of their strains? What do you have going besides that?
