Burpee Organic Coconut Coir Seed Starting Mix, Expands to 16 Quarts

This is a great, multi-purpose product that can be used for seed starting, supplementing garden bed soil, mulch, compost additive, etc. Because the coir bricks are shrink-wrapped, they can stay fresh for literal years. All you need to do is grab a big bucket, empty the brick into it, add water, and stir. I usually let mine sit for an hour or overnight so the water absorbs. I use mine for seed starting and filling seed trays. The coir material holds onto water and is loose enough to provide good support for root growth. Seeds start easily in this medium. Other purposes: amending heavy clay soil so it has more drainage or needing to add loose material for growing root veggies like carrots, adding to compost as a "brown" item, for planting containers, covering a garden bed as mulch. This stuff is cheap, multi-purpose, clean (no weed seeds or garbage), and sustainable.

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.

Hydrates quickly and easily to produce a fine starter soil without clumps and wood pieces. No insects flying around or mold in my seed pods. I hydrate one brick at a time since it makes a good deal of soil. Easy to store and economical to buy.

Every year, I start my seeds using Miracle-Gro potting soil, but I’ve always been frustrated by the sticks and debris mixed in—it made it harder for the seeds to sprout. After doing some research, I found this product and decided to give it a try. Right out of the bag, I noticed a huge difference. The soil is super fluffy, light, and completely free of sticks or clumps. It absorbed water well and broke apart easily. To my surprise, my seeds started sprouting within a week and a half—faster than all the previous times. I highly reccomend

There is a SERIOUS amount of mix here, much more than I was expecting, it’s holds an excellent amount of water. I will have enough seed starter for my next few rounds!

I've read about coir for years and thought it a fad. But it persists and I am finding my regular seed starting soil not doing it for me. So, I figure, I will try this instead. I believe it holds moisture much better than regular soil. I planted vinca seeds on the 13th. It is 6:30AM on the 16th and I see the seeds sprouting. According to what I read the average germination is 14-21 days. Last year, I got NO germination at all. I think, I've found a new medium to start my seeds. One thing, I'm going to change. I'm not gonna use plain water to expand them. I am going to mix the water with an organic fertilizer first. I feel that will make the medium even better.

This stuff is great. I wish I knew of this coconut derived soil a long time ago for my house plants. But the awesome part is that it could be dehydrated, compressed into a brick, packaged and shipped like that. It saves quite a bit of weight from needing to be transported. Some of the reviews (more so on some other brands) mention issues with reconstituting the bricks into a full amount of soil. I had none of these problems, and it was remarkably simple to do. I followed the directions, measured the water out and made sure to use warm (filtered) water. The brick instantly sprang to life once I poured the water on it (I used a 5 gallon bucket for one brick and that seemed just right). It took no further work on my part, the brick grew and separated out perfectly until it was just all fluffy soil. No dehydrated brick chunks or excess water remained. I'm definitely ordering more for other potting I need to do.
