Left alone, it takes a long time for that soil life to re-establish, and in the meantime organic feeds sit unused and young plants are slow to root and establish. Startrex reintroduces a dense population of soil bacteria at planting, so the medium is biologically active from the start and root development gets going straight away.\u003c\/p\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainers:\u003c\/strong\u003e mix \u003cstrong\u003e25 g (about two tablespoons) per 5 L\u003c\/strong\u003e of potting soil or coco — \u003cstrong\u003e50 g per 10 L\u003c\/strong\u003e — before planting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutdoor beds:\u003c\/strong\u003e work \u003cstrong\u003e250 g per m²\u003c\/strong\u003e into the soil.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRe-using soil or coco:\u003c\/strong\u003e remove the top 5 cm, the old stem and the large roots, then mix \u003cstrong\u003e25 g of Startrex into each litre\u003c\/strong\u003e of soil or coco and spread it as the new top layer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart of a system:\u003c\/strong\u003e Startrex is the soil-life component of the BioTabs organic growing method, alongside BioTabs tablets, Mycotrex and Bactrex.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e organic soil conditioner and fertiliser (powder)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPK:\u003c\/strong\u003e 3-1-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContains:\u003c\/strong\u003e humus from partially decomposed pressed grapes, beneficial soil bacteria, fulvic acid, silicon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDose:\u003c\/strong\u003e 25 g per 5 L of potting soil or coco; 250 g per m² outdoors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowing media:\u003c\/strong\u003e soil and coco, in containers or open ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e indoor and outdoor — flowers, vegetables, herbs, trees and shrubs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e certified organic fertiliser; Ecocert-approved input; labelled 100% vegan\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\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;\"\u003eBioTabs Startrex · soil and coco · grams per litre of growing medium, not of water\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;\"\u003eFresh potting soil or coco, mixed in before planting\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e5 g\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e50 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#fcfaf4;\"\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;\"\u003eRe-used soil or coco, mixed into the new top layer\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e25 g\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e250 g\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 — BioTabs' own rates.
