It is designed to be used with every reservoir change, giving plants a consistent, immediately available feed through their most active leaf and stem development.\u003c\/p\u003e\u003cp\u003eGrow Big Hydroponic is used from early vegetative growth through to the first sign of flowering, at which point growers typically switch to Fox Farm's Tiger Bloom and Big Bloom for the bloom phase. Maintaining reservoir pH in the 5.8-6.3 range is important for keeping nutrients available throughout the feeding cycle, and a lighter foliar application can be used as a supplemental feed every other week outside direct light.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEarthworm castings and micronutrients\u003c\/strong\u003e in a liquid hydroponic concentrate\u003c\/li\u003e\n\u003cli\u003eFormulated specifically for \u003cstrong\u003erecirculating hydroponic systems\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCovers \u003cstrong\u003eGeneral and Heavy Feeding\u003c\/strong\u003e rates depending on plant demand\u003c\/li\u003e\n\u003cli\u003ePairs with \u003cstrong\u003eTiger Bloom and Big Bloom\u003c\/strong\u003e once flowering begins\u003c\/li\u003e\n\u003cli\u003eCan be used as a \u003cstrong\u003esupplemental foliar feed\u003c\/strong\u003e every other week\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNPK: 3-2-6\u003c\/li\u003e\n\u003cli\u003eTarget pH: 5.8-6.3\u003c\/li\u003e\n\u003cli\u003eGeneral Feeding: 10ml per 4L water, with every reservoir change\u003c\/li\u003e\n\u003cli\u003eHeavy Feeding: 15ml per 4L water, with every reservoir change\u003c\/li\u003e\n\u003cli\u003eSupplemental foliar feed: 2.5ml per 4L water, every other week, not in direct light\u003c\/li\u003e\n\u003cli\u003eSwitch to Tiger Bloom + Big Bloom at first sign of flowering (approx. week 5)\u003c\/li\u003e\n\u003c\/ul\u003e\n\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;\"\u003eFoxFarm Grow Big Hydroponic · recirculating hydroponic systems — vegetative growth\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;\"\u003eApplication\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;\"\u003eGeneral feeding — with every reservoir change\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e2.5 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e25 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;\"\u003eHeavy feeding — with every reservoir change\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e3.75 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e37.5 ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;\"\u003eSupplemental foliar feed — every other week, not in direct light\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e0.63 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e6.3 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 — FoxFarm publish these as 10 ml, 15 ml and 2.5 ml per 4 L of water.
