ZT is safe through flower up to around 5 days before harvest. Spray lights-off, use lighter strength (around 20–30ml\/L) on dense buds, and mist rather than drench to avoid pooling in the heads. The oils evaporate fully so there's no residue or taste impact at harvest.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails style=\"margin-bottom: 0.8rem; border: 1px solid #e0e0e0; border-radius: 6px; padding: 0.8rem 1rem;\"\u003e\n\u003csummary style=\"font-weight: 600; cursor: pointer;\"\u003eDoes it really kill thrips and broad mites?\u003c\/summary\u003e\n\u003cp style=\"margin: 0.6rem 0 0; font-size: 0.93rem; line-height: 1.6;\"\u003eYes — it's one of the few organic options with a track record for both. The key is thorough coverage (underside of leaves, inner canopy, nodes) and three applications spaced 2–3 days apart to catch eggs that hatch after round one. Single passes won't clear any mite — organic or not.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails style=\"margin-bottom: 0.8rem; border: 1px solid #e0e0e0; border-radius: 6px; padding: 0.8rem 1rem;\"\u003e\n\u003csummary style=\"font-weight: 600; cursor: pointer;\"\u003eIs it safe for pets, fish, and beneficials?\u003c\/summary\u003e\n\u003cp style=\"margin: 0.6rem 0 0; font-size: 0.93rem; line-height: 1.6;\"\u003eYes — a key advantage over pyrethrum, which is toxic to fish and reptiles. Keep pets out while spraying, let foliage dry, and release beneficial predators 3–4 days after your last application to avoid hitting them with residual oils.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails style=\"margin-bottom: 0.8rem; border: 1px solid #e0e0e0; border-radius: 6px; padding: 0.8rem 1rem;\"\u003e\n\u003csummary style=\"font-weight: 600; cursor: pointer;\"\u003eCan I mix ZT with other foliar sprays or nutrients?\u003c\/summary\u003e\n\u003cp style=\"margin: 0.6rem 0 0; font-size: 0.93rem; line-height: 1.6;\"\u003eNo — spray ZT on its own.
