Use this for when you start your seedlings!
This is going to be my go-to for when I start my seedlings each year going forward. This does a great job holding onto water as compared to the garden variety bagged seed starting mix that you get from a box store. All of my seeds that I have planted this year in this medium have thrived. The block that you get is a great size and you do not need to use a lot for when you start your seeds. The coco coir block does not have a smell and is not heavy at all. It does take a little bit of chipping away to break off pieces to use, but other than that it is a great product. Highly recommend this for anyone who is starting seeds for their flower or vegetable gardens.

High quality for gardening
Good soil amendment for gardening- particularly for starting seeds or using in pots. Breaks apart easily when left to soak for a bit in warm water. I go through a decent amount of this so I appreciate the value of the large bricks.

OMG thats a ton of COIR!
Since this was pre washed and buffered its just a matter of adding water and dress it up as you see fit. I did break it up before adding water. no rocks sticks or junk was in the block. I damn near filled a large sterlite tub after it hydrated. I filled two 3 gal bags and still have so much for other plant projects. It also works great for tropical plants. wife used some re potting a Christmas shrub from Hawaii. My preference is to use hot water when hydrating. Its great for mycology projects as well as other plant types.

Great quality product. Repeat purchase
Excellent product. Second purchase, consistent quality, good blend of pith and coir. I use it in a drain to waste system and it works great. it is buffered, but you will need to add calmag right away because it looses the cations quick

Large volume!
I had ordered other brands earlier and didn’t notice this was one solid block instead of individual bricks! It was more challenging to rehydrate because I didn’t have a container big enough. My fault. But it is very good to work with and sure seemed to make more “soil.”

No comparison to this other brand I compared it to
I first bought this coco months ago. I've never baught coco before this .. I used it for soil mixes. Added some to my worms bin and Yada Yada.. when it was gone I ordered viagro 11 pound bricks from my local box store. I did this to try and save a few $. Right off the bat .. once hydrated I noticed a huge difference. The viagro had a very earthy smell and was so much darker. I also let some dry out to see if it was buffered. It was not. I've noticed buffered coco can have a white film when dried from buffering with calcium.. . Another difference was when you fluff Nutrifield your hands don't get dirty. You get small bits of coco on them but not dirt. You can rub the coco off with your hands and your hands are cleaner than before fluffing.. The viagro is like playing in dirt. Very dirty hands that need to be washed after.. . Just for fun I washed the viagro. The water was black. Not only that but there was a TON of sand in it. If you wash the NF the water isn't clear but is not opaque.. . Its tinged yellow brown. With absolutely no sand in it.. the biggest difference to me is the smell and feel of the coco. NF. is fluffier better quality coco that they wash and buffer.. They dont just say they wash it they wash it. They don't just say they buffer it they buffer it.. Not only that. It really is a reasonable price for the added work they do to sell a superior product.. . I think I "saved" 15 dollars on 2 big bricks going with viagro. Really I lost money because I'm not using it and bought another 2 bricks from Nutrifield.. . Nutrifield is proof that you can get a great coco for reasonable price. You don't have to spend $50 for a bag like some other name brands. You can get high quality from a brick. You just have to get it from Nutrifield

Great product. Save your back. Use CoCo.
This product saved my back! Open add water and the product is light as air. No more lifting the heavy soil to add to my pots and raised beds. Mix in a little soil and my veggies and gardens are growing nicely. Prices if good, too. I will buy again.
