You know I just realized something that was so obvious I never thought about it.
Every clone only cutting that we share with one another has probably been sprayed with toxic chemicals numerous times over it's existence and passed on to the next stewart.
I used Forbid 4f 5 years ago and I felt slightly evil doing so. It's not like I'm a hippy and avoid synthetics and other modern marvels, but I'm not so detached from nature that I want to use pesticides on my plants either.
I felt a bit of relief when the last Forbid treated plant was replaced for other genetics, getting rid of the residue.
Just a thought, haha.
