Burpee Organic Coconut Coir Concentrated Seed Starting Mix, 16 Quart

This is the best soil additive for raised beds I have ever encountered. Each brick weights next to nothing so I don't need to wheel barrow it any where. Toss it in a 5 gal. bucket, cover it with water and the next day you have around 2 cubic feet of material (it seems to keep expanding for several days). I mix ir with equal parts sifted compost for starting seeds. As a top dressing it really helps retain water and working it into the soil builds bulk and breaks down clay quickly. Wish I'd known about this year's ago!

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.

I was looking for planting soil as my yard is mostly clay-based. I saw this & was immediately intrigued. I purchased 4 to get my seeds started (totally too much lol I underestimated just how much these bricks would yield). I eventually purchased wheel-barrow sized blocks too; just to cover my entire garden.Anyways, my seeds thrived in this soil alternative! I had grow lights & heating mat setup in my seeding room in my basement. The soil has barely any smell to it & it feels like fine potting soil.The leftovers were in a bucket that I covered with a trash bag. It remained wet for weeks after! I eventually dumped it into my outside garden.The only downside I foresee is that this soil will not hold nutrients like regular, in-the-ground soil; so be prepared to have nutrients ready to feed your plants.From my research & trial/errors, I add the following:calcium, magnesium, nitrogen, iron, worm casing fertilizer & nitrogen-based plant food pebbles.Additionally, the soil will dry out in the sun long before the undersoil. So be very, very aware of how much you water your plants. Since this soil dries quickly, you do not want to over-water. That's why I added the worm casing fertilizer; as it is like regular soil & retains moisture. Just keep watch & be vigilant for when you should be watering.Overall, this soil variant is not only cheaper than buying bags of planting soil but it is also not as heavy to carry! Yes there is more upkeep in certain things; but I enjoy gardening work so I don't mind spending extra time doing it.

I use this to mix with other garden products to make my own seed starting mix. It works great to keep the soil light which is especially important for seed starting.

This is a really good quality product. It is much nicer to work with than peat moss. Doesn't have a moldy smell, is nice to the touch, and is very easy to rehydrate and mix. Unfortunately, I found it to be not best for me when it comes to starting seeds, thus 4 stars. It is still great as a peat replacement in potting mixes. My main issue with this product is that it dries out way too fast and I lost some seedlings due to that. Also, it doesn't contain any fertilizers like some other seed-starting products which is good and bad depending on who you ask. I won't be using this for seed starting but will surely consider it for making potting mixes ... when I'll be a millionaire or when this product becomes more affordable, whatever comes first.

The media could not be loaded. So easy to use. No smell. Water retention is amazing. Be ready for an enormous amount of product for your seedlings/planting in the best way possible! 😀 this came as two bricks and one brick filled my 5gallon bucket over 1/2 of the way when it was finally finished absorbing all the water. I’ve previously used the smaller seed ones for trays and this is less work and more for your money. My growth rate has went from 5-7 days to only 3 days for most seedsWill purchase again!

used it to make my own potting soil. Works great

It is so nice not to have to carry another wallet. Looks good bright enough to where I can’t lose my phone and is slim in my pocket.
