Plants take up silicon and lay it down in their cell walls, where it stiffens tissue and helps them cope with heat, drought and attack from pests and fungal disease. Silicium Flash supplies that silicon in a form plants absorb quickly, alongside the main nutrients, so the benefit starts from the first watering.\u003c\/p\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreparing the medium:\u003c\/strong\u003e mix \u003cstrong\u003e75 g per 10 L\u003c\/strong\u003e of organic potting soil or coco evenly through it before planting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrecting a deficiency:\u003c\/strong\u003e make a small hole near the stem, sprinkle in \u003cstrong\u003e25 g\u003c\/strong\u003e, cover with soil and water with \u003cstrong\u003e1 g of BioTabs Bactrex per litre\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMother plants:\u003c\/strong\u003e mix \u003cstrong\u003e100 g (about 160 ml)\u003c\/strong\u003e per plant into the medium and repeat \u003cstrong\u003eevery two months\u003c\/strong\u003e, as a top dressing or in a few holes around the stem.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil and coco only\u003c\/strong\u003e — it is a solid fertiliser and is not for nutrient reservoirs or hydroponic systems.\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 solid organic fertiliser with silicon (powder)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPK:\u003c\/strong\u003e 4-4-4 on the current 'New Formula' label (original formula 4-3-3)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContains:\u003c\/strong\u003e silicon (Si), nitrogen, phosphorus, potassium, calcium, magnesium, trace elements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelease:\u003c\/strong\u003e immediate, with the remainder over about two months\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDose:\u003c\/strong\u003e 75 g per 10 L of growing medium; 25 g spot treatment; 100 g per mother plant every two months\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowing media:\u003c\/strong\u003e organic potting soil and coco, in containers or open ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e indoor and outdoor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e Control Union certified 100% organic ingredients\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 Silicium Flash · 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;\"\u003eMixed into fresh potting soil or coco 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;\"\u003e7.5 g\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e75 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 directions.
