Never Buffer Your Coco Again

By Max Yield Labs, Bringing You AI-Assisted Advancements In Coco Growing Technology To Your Doorstep

Most "cal mag'd" coco on the market is just buffered — or worse, rinsed to a low EC and called done. This one is buffered and loaded with slow-release calcium and magnesium, so the cal-mag lives in your medium instead of in a bottle on your shelf.

1. The problem with "cal mag'd" coco

Raw coco is hungry. Drop a plant into unbuffered coir and it strips calcium and magnesium straight out of your feed — your seedlings come up speckled, rusty, and stalled while the medium eats your cal-mag for breakfast.

So you buffer it yourself, or you buy "cal mag'd" coco. Except half the bags sold as "cal mag'd" are just flushed to a low EC. Low EC doesn't mean buffered. A rinsed brick reads clean on a meter and still strips your feed in week one. And even when it is properly buffered, you're still hauling out the cal-mag bottle every single feed — measuring, dialing, and chasing deficiencies the day you forget.

2. How Cal Mag'd Coco solves it

Two steps, not one.

First, every batch runs through our Dual-Stage Cation Exchange Saturation Process: a concentrated calcium nitrate and magnesium sulfate soak, drained, then run again with fresh solution, then rinsed below 0.4 EC. That saturates the coco's exchange sites with calcium and magnesium so the medium stops stealing them from your feed. Low EC doesn't mean buffered.

3. What's inside

• Pure coco coir base — buffered via the Dual-Stage Cation Exchange Saturation Process, washed below 0.4 EC

4. What you'll see in your grow

From day one, no cal-mag lockout dragging your seedlings backward — they come out of the gate green instead of speckled. Through veg and into early flower, the built-in reserve keeps calcium and magnesium moving without you reaching for a bottle. Less rust spotting on the lower leaves. Fewer "why is it doing that" mornings. Steadier, cleaner growth, because the medium is feeding cal-mag instead of fighting you for it.

5. How to use it

Hydrate the coco, let it drain, and plant straight in. Run your normal base nutrients at your normal pH. For most grows, that's the whole story — simply use your cal-mag.

6. Sizes

Available in 10L, 25L, 50L, and 100L. The 100L ships as two 50L bags to stay under carrier weight limits — same coco, just split across two bags.

This particular size is 50L. Enough to fill 4 three gallon pots to the brim.

7. Bigger order? 

Orders over 100L qualify for special pricing.
