This 70/30 mix gives you all of the benefits of Plagron Cocos Premium, but with an added 30% dose of perlite. Perlite is a porous, volcanic rock that is often used in horticulture to improve drainage, aeration, and water-holding capacity. Perlite helps to create a more open, well-draining growing medium that is less prone to compaction and waterlogging. This can be highly beneficial for plants, as it increases oxygenation rates, allows them to take up more water and nutrients, improving overall plant growth. 
 
Mixing coconut fibre and perlite is an incredible combination - getting the best out of each substrate. The coco coir is sold pre-rinsed and buffered, and is ready to use straight out of the bag.
 
Plagron Cocos Perlite 70/30 fits in with Plagron's 100% COCO growing style, so it teams up nicely with Cocos A&B base nutrients. Hydro A&B will work, but it's not recommended. Check out the rest of the Plagron Nutrients range for an array of additives.
