Would like to know more about horse tail tea....I grow inside 4x6 ran contiuous harvest fror 2 years no prbs and then the dreaded PM hit. I killed everything, sterilized the room and all gro equipment and started over. P came back within 4 weeks, tried milk, h2o2, mild bleach waste of time. Had to ensure no large temp drop at night (waaa no more color) with a space heater to keep around 74 at night 78-84 during daylight. Then had to eradicate with wettable sulphur. Follow directions and spray entire plant in veg, a day before going into bloom until dripping. It looks a bit like PM when it dries. Once in bloom there has been no PM 4 months later. Be sure to correct conditions in room first (clean dry warm floor) follow directions for mixing. The room has a residual sulphur smell for a while, but the new growth and buds do not carry the sulphur coating and taste perfect. The only problem with this treatment (IMO) is that if you tend to get spider mites, they will not settle on the lower fan leaves, they just go for the new growth, bringing them into close proximity of the bud (which normally gets mites last. Hope this helps, cheapest and way safer than a burner (ask your canary). Sulphur was less than 10 bucks
