It’s really easy, but I get it. Try it after harvest then, so you can see how easy it is. In a bucket I used to grab the plant stalk with the bucket upside down. It slides right out.
I usually see it’s effects within 7- 10 days or so, but maybe its all the rain we get here. A massive burst of new flowers is seen in that timeframe. I Just added some about that long ago and I see the effects now. A bubbled tea with guano is a better option for an auto though. Good point.
