well there is hope for most of the woods girls here is a before and after of one of the plants that I sprayed in my green house, there not going to yield pounds but maybe a zip or 2 , heres a good one I mixed up a jar of the spray that killed and damaged my woods/green house girls and sprayed some weeds didn't affect them at all then when the sun came out I sprayed some more still didn't affect any so why did it kill so many so fast baffling
