House \u0026amp; Garden's Coco A\u0026amp;B is properly concentrated — meaning it lasts longer per bottle than most competitors — and it handles coco's quirks without faffing about. Designed for coco specifically, which means you get the calcium and magnesium balance right out of the tin. One growers come back for.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eHouse \u0026amp; Garden Coco A\u0026amp;B is a \u003cstrong\u003etwo-part liquid base nutrient system\u003c\/strong\u003e formulated specifically for plants grown in coco coir. Unlike generic hydroponic feeds, this is built around coco's unique characteristics — it accounts for how coco binds calcium and magnesium, and delivers all the main nutrients your plants need to thrive from seedling through to the end of flowering, using only pharmaceutical-grade ingredients with zero bulking agents or filler.\u003c\/p\u003e\n\u003cp\u003eThe system comes as Part A and Part B, which must be added separately to your water (in that order) to avoid chemical reaction and sediment. It's highly concentrated, meaning a little goes a long way, and it works just as well in hand-fed pots as it does in automated drip or recirculating systems.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eHouse \u0026amp; Garden Coco sits in the \u003cstrong\u003equality-focused, mid-premium tier\u003c\/strong\u003e of two-part coco nutrients.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVs.

Get that wrong and you'll get sediment; get it right and you've got clean, stable nutrition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMixing (critical step)\u003c\/strong\u003e\u003cbr\u003eFill your tank two-thirds with water, add Part A and circulate well, then add Part B. Never add both at once — they'll react. Adjust pH to 5.8–6.3 after mixing. Then add any boosters if you're using them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDosage\u003c\/strong\u003e\u003cbr\u003eUse 1–2ml of each part per litre of feed water (so 1ml Part A + 1ml Part B per litre). This gives you an EC of around 1.2 at the start of vegetative growth. Follow the growth schedule, building up to an EC of around 2.0 by the end of flowering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHand-feeding pots\u003c\/strong\u003e\u003cbr\u003eWorks perfectly.

In recirculating systems, monitor EC and pH regularly — coco is inert, so the nutrient solution won't buffer over time the way soil does.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThroughout the cycle\u003c\/strong\u003e\u003cbr\u003eThis is an all-in-one base feed — no need to swap formulas between veg and flower.
