I understand that Neem oils are more widely available, but that doesn't make them superior. Horticultural oils (provided they are not petroleum based) are also organic, cheap and perhaps even safer than Neem oils due to the fact that they are non-systemic.

I began using horticultural oils at the advice of a friend who works for the Horticultural Department of my local university. He's not 420 friendly, so I told him I was growing vegetables and herbs at home and needed an organic method to control an infestation of spider mites. He suggested using highly refined vegetable-based horticultural oils because, unlike neem-based oils, they are practically odorless and won't be absorbed by the plants.

I use 10E Hort oil on most garden pests. At a rate of 1%. Outdoors. It isn't the dormant oil of yesteryear. Once dormant oil was only used in the dormant season, hense its name. That has changed. It is highly refined and is more akin to baby oil then motor oil. Now we spray it during the growing season, beginning in March, for early mites and scale insects. It works by smothering insects which breath through their skin. If used at the right stage in an insects life cycle it is very effective.
It is not absorbed systemically through the plants leaf tissue and essentially evaporates after application leaving little residue.
It is categorized as a pesticide but it doesn't share the same chemical make up of other petro chemical based pesticides.
It will work on mites in the immature stages but not on adults. And not on mite eggs either.
It is safe to use on food crops. Personally I would only use it outdoors on MJ and not in flower. A personal choice.
Neem is a new term for me. Since I joined RIU in fact. I have not used it. I suspect it's a lot like Hort oil if not the exact same thing. I've read a lot by growers here that it works. And some horror stories that it burns leaves, which is avoidable by spraying in the evening and never on hot days above 90F. But I wouldn't spray anything on my buds. But that's just me.
My experience with Hort oil is professional in nature. I use it at work. Since the state certified me to spray it and I had to take an exam to get that certification I feel I'm qualified to talk about it here. Hope it helps.

Hell no. People in India take it internally. Its The Shit!
Peppermint oil is great too also rosemary. I have a big outdoor organic vegetable garden in bug infested texas. I use nothing but Neem and BT. When it comes to neem an ounce of prevention is worth a gallon of cure literally. Spray neem on a regular basis like 2 week intervals up to the third week of 12/12 and you will NEVER get spider mites.

Horticultural oil is a petroleum distillate. Neem oil is a plant extract from the Neem Tree. It grows in India. There is such a thing as food grade neem oil intended for human consumption. Horticultural grade neem oil is approved for same day harvest by most organic food certifying agencies. Neem oil's mechanism is hormonal. It is an anti feedant. It is also anti-fungal. It kills fungus gnats. You can not in ethically spray petroleum distillates on cannabis and call it organic nor is it fit for medical use. I could go on but a quik google of neem oil will bring up planty of info.
