Alongside its core NPK ratio it carries \u003cstrong\u003eearthworm castings and Norwegian kelp\u003c\/strong\u003e, the combination FoxFarm credits for sturdier, healthier growth rather than fast, leggy stretch.\u003c\/p\u003e\u003cp\u003eThe vegetative stage sets a plant's eventual ceiling - a thin structure here limits how much weight it can carry once flowering begins, whatever the bloom feed does later. Grow Big is designed to be pushed hard through this stage, building the branching and canopy structure that a phosphorus-led flowering feed needs something substantial to work with.\u003c\/p\u003e\u003cp\u003eIt is used from early vegetative growth through the switch to flower, kept stable in solution at a controlled pH, then tapered off in favour of Tiger Bloom and Big Bloom. It also works as a supplemental foliar feed at a reduced rate, sprayed on both sides of the leaf away from direct light.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-nitrogen liquid concentrate\u003c\/strong\u003e built for the vegetative stage\u003c\/li\u003e\n\u003cli\u003eContains \u003cstrong\u003eearthworm castings and Norwegian kelp\u003c\/strong\u003e for sturdier structure\u003c\/li\u003e\n\u003cli\u003eBuilds the stem strength and branching a heavy flowering finish depends on\u003c\/li\u003e\n\u003cli\u003eSuitable for \u003cstrong\u003esoil and hydroponic systems\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCan also be used as a \u003cstrong\u003esupplemental foliar feed\u003c\/strong\u003e at a reduced rate\u003c\/li\u003e\n\u003cli\u003eTapered off as the plant transitions into flowering, handing over to Tiger Bloom and Big Bloom\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPK ratio:\u003c\/strong\u003e 6-4-4 (Soil formula, as listed here)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey inputs:\u003c\/strong\u003e earthworm castings, Norwegian kelp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth stage:\u003c\/strong\u003e vegetative through early flower transition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended pH:\u003c\/strong\u003e 5.8-6.3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable media:\u003c\/strong\u003e soil, hydroponic systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart of:\u003c\/strong\u003e FoxFarm's three-part liquid programme with Tiger Bloom and Big Bloom\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 · soil and hydroponics · 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;\"\u003eThe eight printed vegetative applications, across their full printed range\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e1.3–3.91 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e13–39.1 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 — \u003cstrong\u003eFoxFarm publish this as teaspoons per US gallon of water\u003c\/strong\u003e, printing the sequence 2 · 3 · 3 · 2 · 2 · 2 · 2 · 1 tsp per gallon across eight applications — a range of 1 to 3 tsp, or 4.93 to 14.79 ml per US gallon by their own conversion of 1 tsp = 5 mL.
