Amazing! Two brick sized blocks come together and just one block gives you so much soil. I used the exact measure of water it said in the instructions but it seemed like it needed more. Used this for my daughter’s science experiment and the tomato plants are growing nicely with just water and sun!

This is my first time using this and I just ordered two more packs today as it works SO well! In just one week I've got butternut squash sprouts, which I was not expecting so fast! I already need to separate them and order large containers to accommodate them! This stays moist, it does not smell, it is extremely easy to use. It expands quite a bit once wet. It is very soft to the touch and so easy to work with. It goes a very long way! I think this is my new staple in gardening!

I purchased this coconut coir thinking that it was plain/untreated so that I could use it to set up a worm farm composter. When I soaked the brick to expand it, it gave off a strange scent. Maybe fertilizer? I was concerned that whatever was making the smell might harm my worms, so I put this coir aside for gardening purposes and used a different brand of coco coir that just smelled like dirt for my worms. Overall it seems like a great product! It has been working well for plants. I only deducted one star because it did smell quite strongly.

I have used Burpee seed starting products before, and always found them to be high quality. This was the first time using the Burpee Organic Coconut Coir Concentrated Seed Starting Mix, 16 Quart, but it won't be my last! It is now my favorite seed starting medium. It arrives as a dehydrated block, wrapped in a thin plastic. I was suspicious of how it would absorb the water and rehydrate, as I've found highly dehydrated products challenging to rehydrate quickly. However, I was impressed with how easy it was to fully rehydrate this starting mix. I added it to a bucket, added the suggested amount of water and within just a few minutes the water was absorbed and the seed mix was rehydrated. I was able to have my seeds sown and ready to germinate within an hour of the package arriving at my door!My seeds germinated well, and have gone on to produce high-quality seedlings.I didn't use all the mix in one go, once rehydrated it expanded, and there was more than I needed for my trays. I stored the bucket in my garage until I needed it again a few weeks later. The water had evaporated from the mix, but I was able to add more water and quickly be ready to sow more seeds.I will be ordering more once this has run out. I highly recommend the seller and the product.
