Green Planet's Professional Coco 70/30 is a ready-to-grow substrate that blends 70% buffered coco coir with 30% perlite in a large 53L bag. The coco holds moisture and buffers your feed; the perlite keeps the root zone open and oxygenated. It's RHP certified, pre-rinsed and pH-balanced, so there's no soaking or buffering to do — open the bag, fill your pots, and plant.

The Grow Guys Tip
  • The 30% perlite makes this drain faster than straight coco, so feed a little and often rather than heavy, infrequent waterings.
  • It's already buffered, but a light cal-mag through your early feeds is cheap insurance in any coco mix.
  • It takes worm castings and dry amendments well if you want to build it out into a living mix.

How to Use

1
Open the bag and fill your pots, beds or system straight up — there is no pre-soak or buffering step needed.
2
Plant into it as you would any premium coco medium, then water in to settle the mix.
3
Feed with a coco-suitable nutrient program. Because the perlite drains fast, little and often works better than heavy soaks.
4
Store any unused mix in a cool, dark spot above 4°C to keep it fresh for next time.

FAQ

Do I need to buffer or soak it before planting?

No. It comes buffered, pre-rinsed and pH-balanced, so it's ready to use straight from the bag with no soaking or charging step.

Can I use it in drip and hydro systems?

Yes. The 70/30 blend works as a standalone medium, in drip and recirculating systems, or as a soil amendment.

Do I still need to run cal-mag?

Yes, it's still worth it. Even buffered coco can draw on calcium and magnesium, so a light cal-mag through your feeds is good insurance against deficiencies.

What is RHP certification?

RHP is a growing-media quality mark that checks a substrate for water absorption, air content, pH, nutrients and purity, so you get clean, consistent media in every bag.

How should I store an open bag?

Keep it cool, dark and above 4°C. Reseal or cover the bag to stop it drying out.
