CX Horticulture Coco Base A&B — Two-Part Coco Nutrients Built for Clean Uptake
Best for: Coco growers wanting a proven, straightforward two-part base that covers the full growing cycle without faffing about
Our thoughts
CX has been doing this properly for 20 years. Coco Base A&B is commercial-grade kit that just works — no pH Perfect wizardry, no complexity tax, just solid plant feeding. Mix it steady, keep your EC sensible, and watch it deliver. One growers keep coming back to.
CX Horticulture Coco Base A&B is a complete two-part coco nutrient system formulated specifically for growing in coco coir media. It's designed to handle the full cycle — vegetative growth through to flowering — without requiring you to swap products halfway through. The formula addresses coco's quirks directly: preventing nitrogen drawdown (a common headache in coco), managing calcium uptake, and ensuring clean micronutrient availability across your entire grow. Simple to mix, reliable to feed, and built on real plant-tissue analysis rather than guesswork.
This is end-of-line stock from a commercial supplier, so you're getting proper kit at a much lower price than you'd find in garden centres.
How it compares
CX Coco Base sits in the proven commercial-to-serious-hobby tier of coco nutrients.
-
vs. CANNA Coco: Same precision and reliability, significantly lower cost; CANNA is the premium brand, CX delivers the same science without the markup
-
vs. Advanced Nutrients Sensi Coco: CX requires manual pH management (simple enough); Advanced Nutrients charges extra for pH Perfect automation — you're not paying for features you don't need
-
vs. Plagron Cocos: CX is more synthetic-precise; Plagron leans organic — same performance category, different philosophy
-
vs. Plant Magic Coco Grow: Comparable quality; CX has longer commercial heritage (20 years) and Hot Mix Technology differentiation
Straight truth: if you want proven, no-nonsense coco feeding at entry-to-mid pricing, CX Coco Base competes with the household names on performance and beats them on value.
Usage guidance
Basic mixing
Add Part A and Part B in equal ratios. Standard recommendation is 2ml/L of each (1ml A + 1ml B = 0.6 EC; 2ml A + 2ml B = 1.2 EC). Always shake the bottle well before use. Add A first, stir, then add B, stir again. Don't skip the mixing step — two-part systems need proper blending to prevent nutrient lockout.
Run-to-waste setups (hand feeding or automatic drip)
Use 1.2 EC as your baseline (2ml/L total). Feed to runoff, check your EC is stable, and adjust only if plants show deficiency signs. Coco drains fast; consistency matters more than daily tweaks.
Recirculating systems (flood tables, NFT)
Same dosing logic. Monitor your reservoir EC weekly. Coco doesn't interact with the nutrient solution the way soil does, so your EC will climb slower and more predictably — this is normal and fine.
The coco-specific bit
Coco naturally absorbs calcium and magnesium while releasing potassium. CX Coco Base compensates for this in the formula itself — you don't need to overthink it, the nutrient ratio is already balanced for coco's quirks. Just mix as instructed and feed steady.
Through the cycle
Same formula works for vegetative and flowering stages. You don't swap products. This keeps things simple and stable — exactly what coco responds to.

Our take
This is proper kit at sensible money. CX has 20 years of commercial growing behind it, and Coco Base A&B sits at the heart of that. It's not flashy — no pH Perfect, no exotic additives, no marketing fluff — but it delivers exactly what a two-part coco base should: clean, stable feeding without the guesswork.
If you're building a coco setup and don't want to spend premium prices, this is worth picking up while clearance stock lasts. Does exactly what it should, day in, day out.
