They come straight from California, home to some of the world's biggest and best growers, and feature high-grade, chelated mineral nutrients that push your plants to the next level, for faster growth, stronger plants and bigger yields.\u003c\/p\u003e\n\u003ch3\u003eHow Cali Pro Grow A\u0026amp;B Works\u003c\/h3\u003e\n\u003cp\u003eCali Pro Grow A\u0026amp;B has a macronutrient profile built for the vegetative stage, with increased nitrogen to accelerate the growth of new leaves and branches. It uses only high-grade chelated minerals, which are more readily absorbed by the roots and taken up across a wider pH range than typical mineral nutrients, so small pH swings are less likely to cause deficiencies. That makes it an excellent base nutrient for beginners and experts alike.\u003c\/p\u003e\n\u003ch3\u003eAbout\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart of the Emerald Harvest range, California's finest\u003c\/li\u003e\n\u003cli\u003eA simple and easy to use, yet highly effective base nutrient\u003c\/li\u003e\n\u003cli\u003eChelated minerals for increased nutrient uptake across a wide pH range\u003c\/li\u003e\n\u003cli\u003eFormulated after years of research and development\u003c\/li\u003e\n\u003cli\u003eHigher nitrogen for rapid growth during the vegetative stage\u003c\/li\u003e\n\u003cli\u003eWorks in any grow medium or system\u003c\/li\u003e\n\u003cli\u003eProvides all of the essential macro and micronutrients\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow To Use\u003c\/h3\u003e\n\u003cp\u003eUse Cali Pro Grow during the vegetative stage, then switch to Cali Pro Bloom when transitioning to flowering, after flipping your plants to a 12\/12 light cycle. Emerald Harvest recommend making the swap in the second week of flower. Add Cali Pro Grow at 0.5ml to 1.3ml per litre of nutrient solution.\u003c\/p\u003e\n\u003cp\u003eBoth parts of a 2-part nutrient are designed to be used together in equal amounts. Using only part A or part B, or unequal amounts, will give an unbalanced nutrient solution and will almost certainly lead to deficiencies.\u003c\/p\u003e\n\u003cp\u003eNever mix nutrients, boosters or additives together in their concentrated form. Add each one to your reservoir or feed water in turn, stirring well before adding the next.\u003c\/p\u003e\n\u003cp\u003eThe ideal pH range after mixing is 5.8 to 6.3. Keep water temperatures between 18°C and 21°C, using a chiller if necessary.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGuaranteed analysis:\u003c\/strong\u003e Part A: 3-0-0; Part B: 2-2-5\u003c\/p\u003e","brand":"Emerald Harvest","offers":[{"title":"1 Gallon (3.79 L)","offer_id":49858118091098,"sku":"BFH-EMCP-G1G","price":79.99,"currency_code":"GBP","in_stock":true},{"title":"2.5 Gallons (9.46 L)","offer_id":49858118123866,"sku":"BFH-EMCP-G2G","price":178.95,"currency_code":"GBP","in_stock":true},{"title":"0.95 Litre (1 US QT)","offer_id":50881837597018,"sku":"BFH-EMCP-G1QT","price":33.99,"currency_code":"GBP","in_stock":true},{"title":"1 Litre (Decanted)","offer_id":51629864878426,"sku":"BFH-EMCP-G1LDEC","price":15.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/9861\/4106\/files\/500327_-_emerald_harvest_cali_pro_grow_20_litre_1.webp?v=1731844515","url":"https:\/\/blackflaghorticulture.com\/sq\/products\/emerald-harvest-cali-pro-grow-a-b","provider":"Black Flag Horticulture","version":"1.0","type":"link"}
