Comment on the no flush community but uses seven dust on or around cannabis. That would make all my bud instantly unsellable when it comes from the labs. I don't flush, grow commercially and have stellar test results and remarks from those that get my bud. I'm not fully organic anymore either. Sounds like you may not know what you're doing and yet give advice.
Yes, but any bud with a noticeable neem taste would probably fail the same tests.
I don't use sevindust in flower, only veg. I generally only use on soil, and the floor of the veg box. It's not absorbed by the plants, and under ideal dry conditions has a half life of ~60 days. In wet conditions it's about 4 days.
I reverse water soil in air pots, there's no way anything stays dry for 48 hours, I SUBMERGE my pots in water.
If I have mites, then yes I use the sevin directly on my foliage in *veg*. This will be washed off in 48 hours in most cases. I have never used it beyond the first day from flipping to 12/12.
I don't doubt that some nutrients leave no negative taste, but when I used general hydro flora, I could definitely taste something weird if I didn't flush... The biggest problem is a tiring smoke, something that makes you want to extinguish a blunt/joint before it's a roach. That was reality for me on unfinished plants on my old schedule.
But yes, I defend saying that neem oil tastes bad..... I mean.... It does.
I'm on Jack's now, and so really don't taste a difference flushed or not. I give ph'd water for the last ~2-3days myself.
Edit, I'm proficient at hydro and salt-soil, I don't know *dick* about organics. I grew full time with a partner for couple years. The grow was surrounded by moldy forest, and bugs. Beneficial predators and bacteria never cut it for us. Everything had to be nearly sterile, or it would rot. We became bleach enthusiasts.
So I'm the far opposite from organic, I mean no disrespect to organic growers, it just never panned out for me.
I have a nice environment now, no mold or bacteria..... But there were mites killing my landscaping last year (came from a nursery, a Japanese maple). Enter sevindust. Then my veg box got infested by mites; ?? Sevindust???
