Want the control of coco with a faster-draining, more open root zone?
Tropic 70/30 Coco Mix combines 70% washed and buffered coco coir with 30% perlite, giving you the moisture retention coco is known for with extra drainage and air around the roots.
It's already blended to the right ratio, so there's no need to buy separate bags of coco and perlite or spend time mixing your own substrate. Open the 50L bag, loosen the media and you're ready to fill your pots.
With RHP certification, a stated pH of 5.8 and EC of 0.8, Tropic 70/30 gives you a reliable starting point for hand-watered coco setups and automated dripper systems.
Coco already gives you a strong balance between moisture retention and oxygen around the roots. Adding 30% perlite makes the structure even more open.
Perlite creates additional air spaces throughout the pot, helping nutrient solution move through the substrate while allowing excess run-off to drain away more freely.
That makes a 70/30 mix particularly useful if you're feeding regularly or using an automated irrigation system.
You still get the even moisture distribution of coco, but with faster drainage and more air available around the root zone.
One of the main advantages of growing in coco is the amount of control it gives you over nutrition.
Tropic 70/30 works particularly well with regular irrigation because the added perlite helps stop the root zone becoming overly dense or waterlogged.
With drippers, fresh nutrient solution can move through the pot efficiently while excess run-off drains away. When hand watering, you get the same open structure while the coco continues to retain useful moisture between feeds.
Irrigation frequency will depend on plant size, pot size, environment and how quickly the substrate is drying, so adjust your watering rather than relying on a fixed schedule.
Coco preparation matters.
The coco used in Tropic 70/30 is washed and buffered before being blended with perlite, giving you a more dependable medium straight from the bag.
It also carries RHP certification, providing additional reassurance over substrate quality and consistency.
The current formulation contains a light PG-Mix starter charge, so it isn't completely unfertilised. You'll still need a proper coco feeding programme as plants establish and develop.
If you're growing in Tropic 70/30, we'd pair it with the Shogun Complete Coco Nutrient Kit.
The kit is built around Shogun Samurai Coco A&B and gives you a complete coco-specific feeding programme with the supporting additives needed throughout the grow.
It's a natural match for Tropic 70/30: the media gives you the drainage, aeration and control of coco, while the Shogun kit supplies nutrition specifically designed for that style of growing.
If you already know you want to grow in coco, 70/30 is one of the easiest ratios to work with.
You get enough coco to hold moisture evenly, but there's plenty of perlite in the blend to keep the root zone open and allow excess feed to drain quickly.
It's especially useful with dripper systems and more frequent irrigation, where you want the media to stay well aerated between feeds.
The other advantage is convenience. Instead of buying coco and perlite separately, measuring the ratio and mixing it yourself, Tropic gives you a washed, buffered and ready-mixed 50L bag at a sensible price.
Pair it with the Shogun Complete Coco Nutrient Kit and you've got a straightforward foundation for a complete coco grow.
Don't compact the mix when you're filling your pots. The 30% perlite is there to keep the root zone open and well aerated, so fill the pot loosely, gently settle the substrate and let the structure of the media do the work.
Do I need to add fertilizer as well - for small plants?
Hi
We would recommend using a product such as Shogun Start for small plants. Once your plants are a suitable size you can then move onto a product like Shogun Coco A&B
