House \u0026amp; Garden Top Booster provides ample quantities of these crucial nutrients in a highly absorbable form. When used alongside your regular base nutrient, Top Booster guarantees that your plants receive an uninterrupted supply of these essential elements. Additionally, Top Booster is fortified with iron, promoting healthier leaves. The result? A remarkable increase in the number of flowers and flowering sites, as well as a substantial enhancement in the weight and quality of your yields.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eHow to Utilise H\u0026amp;G Top Booster\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eHouse \u0026amp; Garden recommends applying Top Booster at a rate of 1.5ml per litre for 3-4 days, commencing three weeks before harvest. For an added edge, we suggest the following approach: Initiate Top Booster at a rate of 0.33ml per litre as soon as flowering begins (typically around week 2 or 3 of the flowering cycle) and continue this regimen until it's time for the final flush (a technique we call the \"trickling method\"). By supplementing in this manner, your plants will benefit from a prolonged exposure to the essential blooming components in Top Booster, resulting in denser and higher-quality blooms.\u003c\/p\u003e\n\u003cp\u003eAs with all nutrients, boosters, and additives, it's essential never to mix them in their concentrated form straight from the bottle.
