This all-natural growing medium looks and feels like soil, but it's much closer to hydro. Read on to find out why you should pick up a bag or brick of coco coir for your next grow.

Coco Coir is one of the most versatile mediums you can use to grow cannabis or just about anything else. This soilless mix is a lot like peat moss, but unlike peat, it's sustainable and eco-friendly. It takes centuries to re-grow peat moss once it's harvested, but to get more coco coir, all we have to do is grind up more coconut husks. And, get this - those coconut husks used to be thrown away as useless junk. That's a double thumbs-up in our book, but the benefits don't stop there. Here are a few more reasons why we love coco:


Compared to growing in soil, you will get bigger plants from smaller pots if you switch to coco coir. This soilless mix can be treated like soil in many ways, but it's really a semi-hydro technique that gives the roots better access to air and nutrients for faster growth. Better root development always leads to bigger, healthier, more productive plants.


Because coco coir drains really well, it's almost impossible to overwater your plants under normal conditions. Even saturated, coco coir retains about a 70:30 moisture to aeration ratio so that the roots never sit in stale, anaerobic water. As long as you never let the coco dry out completely, you'll get good results whether you hand water to runoff every few days, or use a drip system to deliver smaller amounts of fresh water and nutrients every few hours.


Coco coir is fairly inert and doesn't hold onto nutrients for long. If you have a deficiency, you can correct by supplementing during the next watering cycle, and the coco coir will make those nutrients immediately available to your plant's hungry roots. On the other hand, if you overfeed, a quick and thorough flush will remove practically every trace of nutrients from the coco so that you can start over.


Not only does coco coir reduce waste at its source, it reduces waste for the grower. After harvest, give your coco a quick flush and it'll be ready to go back in the pot and nourish a new plant. If you'd prefer fresh coco coir for each cannabis grow, mix the old coco into your outdoor garden to improve the quality of the soil. There's never a good reason to throw coco coir in the bin.


Drumroll, please! The best reason to switch to coco coir is that you'll get much bigger yields than if you were growing in soil. The overall harvest may not be quite as big as going full hydro, but they're pretty close, and coco is much easier to deal with. It's a great compromise that will make your plants grow faster, get bigger and yield up to 25% more. It also makes coir a great stepping stone to hydro if you eventually want to give it a go.

Eco-friendly, versatile, easy and more productive? With those benefits, we can't think of a single reason not to use coco coir. Available in pellets, bricks, sheets and ready-to-use bags, coco coir can be found almost anywhere you can purchase potting soil, and in a pinch, you can even find it in the reptile section of your local pet store.
