Review: Love these - These are awesome! They expand super well and quickly. High quality for a low price. I use them for both my plants and my tarantulas and they work great. They hold water well while still allowing it to drain.
Review: Great stuff - I use this product for seed starting. I have been very impressed with it so far - absorbs water quickly, expands to around half of a 4 gallon bucket, great sterile medium, quite fine and uniform, and super convenient to store. Per pound, not the cheapest way to buy coir, but the small blocks were worth it in convenience, especially if you are just doing a flat or two of seeds at a time and don't have a lot of storage space. As far as how well seeds grow, I'm just getting into the season, so can't give definitive answers, but my first couple batches of seeds are up and doing well. I didn't sterilize my pots, so have had some issues with mold growth on the surface if I don't top water. My yellow onion starts have struggled some with damping off - but they always do for me, so I wouldn't blame this medium - but at the same time, it didn't solve it, either. I did mix with a little organic fertilizer as there is really nothing to this stuff as far as nutrients go, and your starts are going to need something to grow on after they're up. I did no fancy treatments, just poured warm tap water on it in a bucket until it was completely expanded and mixed in a little fertilizer. Works for me - I'll buy again.

**Q: How many quarts does each brick yield?**
A: Each brick can expend up to: 9.5 quarts (9 Liters)

**Q: Is this product treated with Trichoderma? Looking to use for a terrarium but I don’t want it turning green and needing to be replaced every 3 days**
A: It is great for terrariums. I have used this for my Sulcata for going in 2 yrs. The best substrate and no it does not turn green. I change my Torts coco coir every 3-4 months. I highly recommend it.

**Q: How much water do you add per brick?**
A: I placed each brick separately in a 5 gallon bucket and initially added 2 quarts then added as needed so I didn't over saturate the material.

**Q: What is it's ec exactly?**
A: Electroconductivty or EC is how salts in the media are measured. The higher the EC, the higher the salts. You want low salts for good plant growth.
