Gro-Med Coco Coir Brick 10 lbs – Expands to 80 Quarts – NPK Enriched Organic Coconut Coir – Potting Soil for Indoor Outdoor Plants, Seed Starter, Vegetables, Mushrooms, Gardening Use

These are amazing. When watered, these bricks become much larger than when they are dry. I've been using them in my raised bed gardens to lighten the weight of the soil, add nutrients, and make the soil less dense making it easier for vegetable and flower roots to develop. I've also used these with potted plants to help retain moisture and make the soil less dense. It's clean, easy to use and, so far, has been a great addition to prepping my raised bed gardens this year.

Love this dirt. Good quality for the price. It expands so I filled up a 12 gallon bucket, a 10 gallon bucket (only half way), and a 3 gallon bucket. It needed wayyyy more water than the box said to add though and it soaks it up pretty quick. I did notice my plants sprouted faster than the package said they would but idk if that’s the soil or what

Great growing medium. I've used it for indoor cannabis growing and have had no issues whatsoever with it.

I wanted to give it five stars but it did not seem to promote the growth of the plants very well. Admittedly, I did not add fertilizer or any other amendments. And that is probably the reason. So if I were to use this again I would probably mix in some compost with it. Maybe a four to one ratio. Four coco to one compost. The compost would have to be very well rotted and just fine matter. If used for seed starting. It was very impressive and the fact that it was a large volume for the price. Very easy to wet and have it expand into potting soil. Just remember that it is basically a potting media with no nutrients.

Perfect drainage for cacti and succulents in the dry hot Arizona heat. I use this with my indoor plants also, never overwatering or no clogging for this medium. Good stuff for sure, and you can pre-fertilize it before adding plants. Win win Edit: tried using a different brand/seller for a faster delivery. There is definitely a difference between the two. I will not buy the other brand again, it was not like this brand at all. Took longer to make, longer to dry out and clumpy. Gro Med only for growing anything in hot dry climates, it absorbs perfectly and dries out super fast! No perlite or other medium needed.

I'm gonna say this is the best thing in a long time that I've gotten on Amazon as far as the quality. How long it lasts? How much you get? I still have so much of this left and I have used a lot of it. It just goes a long way. I use it in my house plants. I don't use it outside in a yard or anything like that. I've just chip away at the block because it comes very solidly packed. I chip away at the block and I water it and get it. Ready to go, and I've had to waste very little of it, sometimes, in the very beginning. It's a little hard to know how much to chip off the block, so just do a little bit at a time. To make sure you're not taking too much, because it bloats up very largely a lot, and then you end up with excess that you can't use, because you don't really want it to sit there. Wet and get moldy so you want to just take off enough if you're using it in house plants for each plant, just be cautious about that, but this is absolutely great stuffI'm gonna say this is the best thing in a long time that I've gotten on Amazon as far as the quality.

Perfect for starting seeds! I wish I would’ve discovered these sooner!

I had never used coir before ordering this. It was relatively easy to break sections off and it did receive/absorb hot water well. I also like that the smaller package takes up less storage space than sphagnum peat moss. I recommend this coir brick.
