I Noticed a change in smell and taste using it! However, it could have been the mold rot. I did cut out all rot first and then used the serenade! Just a bad scene here but im not sure if I can blame serenade! I will say this though the product Did not work for me at all. Currently Using Green Cure seems a bit better but my outdoor grow is looking like a total loss! Its a shame too as they vegged like rockstars all season! What buds are left are fugly and dont seem to be doing much of anything (anymore)! Good luck! I am Soooo friggen Sad! Next years outdoor grow will either be Autoflowers or something super Mold resistant!! The Church by Greenhouse Or maybe an Iranian Short Season anyway heres either to setting up a grow room or waiting till next year! New England SUX (for raising Cannabis)
