{"product_id":"optic-foliar-atak","title":"Optic Foliar Atak Concentrate","description":"\u003ch2\u003eThe only powdery mildew spray you can apply with the lights on\u003c\/h2\u003e\u003cp\u003eAtak is a copper sulphate-based foliar concentrate that combats and eradicates powdery mildew on contact while signalling the plant to raise its own defence response, without the leaf burn or damage that limits when most powdery mildew sprays can be used.\u003c\/p\u003e\u003cp\u003eIt's suitable from cuttings through to late flower, safe up to one week before harvest, and unusual among mildew treatments in that it can be sprayed while lights are on rather than needing a lights-off application window. Because it's a foliar application, it works across any growing medium - soil, coco or hydro alike.\u003c\/p\u003e\u003cp\u003ePowdery mildew spreads fast in a humid canopy, and most effective sprays either have to be timed around the light cycle or leave a residue that carries through to taste. Atak's lights-on application and residue-free finish mean an outbreak can be hit the moment it's spotted rather than waiting for lights-off, and it can keep being used right up near harvest without a taste penalty.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplies with lights on\u003c\/strong\u003e - no timing workaround needed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEradicates and prevents powdery mildew\u003c\/strong\u003e on contact\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSafe up to one week before harvest\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo residual taste or damage\u003c\/strong\u003e to treated flower\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBoosts the plant's own immune response\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003eFormat: concentrate, mixed with Transport\u003c\/li\u003e\n\u003cli\u003eDilution: 10ml concentrate per litre plus 7.5ml Transport per litre\u003c\/li\u003e\n\u003cli\u003eActive chemistry: copper sulphate and organics\u003c\/li\u003e\n\u003cli\u003eApplication: spray tops of leaves, can be used with lights on\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\u003cdiv class=\"hcs-dosing\" style=\"margin:32px 0 0;border:1px solid #e6e6e6;border-radius:12px;overflow:hidden;font-family:Montserrat,-apple-system,'Segoe UI',sans-serif;\"\u003e\n\u003cdiv style=\"background:#101010;padding:16px 20px;border-bottom:3px solid #efc04c;\"\u003e\n\u003cdiv style=\"color:#ffffff;font-size:17px;font-weight:600;letter-spacing:.06em;text-transform:uppercase;\"\u003eFeed Chart\u003c\/div\u003e\n\u003cdiv style=\"margin-top:6px;color:#b8b8b8;font-size:12px;line-height:1.5;\"\u003eOptic Foliar Atak · foliar spray, cuttings to late flower, any medium\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;color:#2b2b2b;background:#fff;\"\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003cth style=\"text-align:left;padding:10px 20px;font-size:11px;letter-spacing:.08em;text-transform:uppercase;color:#6b6b6b;font-weight:600;\"\u003eComponent\u003c\/th\u003e\n\u003cth style=\"text-align:right;padding:10px 14px;font-size:11px;letter-spacing:.08em;text-transform:uppercase;color:#6b6b6b;font-weight:600;white-space:nowrap;\"\u003ePer 1 L\u003c\/th\u003e\n\u003cth style=\"text-align:right;padding:10px 20px;font-size:11px;letter-spacing:.08em;text-transform:uppercase;color:#6b6b6b;font-weight:600;white-space:nowrap;\"\u003ePer 10 L\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;\"\u003eAtak concentrate\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e10 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e100 ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#fcfaf4;\"\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;\"\u003eOptic Foliar Transport, into the same mix\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e7.5 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e75 ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"background:#101010;padding:12px 20px;font-size:12px;color:#b8b8b8;line-height:1.6;\"\u003e\n\u003cspan style=\"color:#efc04c;font-weight:600;\"\u003eNote\u003c\/span\u003e — Atak is used with Optic Foliar Transport in the same spray, not on its own.
