Viagrow® 650 g (1.4 lb.) Compressed Coconut Coir Premium Grow Media (3-Packs) / A Product of The Harvest Company™

I bought these coconut core bricks for my composting toilet for when I hit the road.The size of a brick but weight next to nothing.But I got the chance to use one brick when I had a handyman remodel my bathroom. He took forever (week).I pulled out a 5-gallon bucket and filled it half way with water. Then threw in a brick and let it sit for a few hours. Then emptied the water. The brick was way swelled up. Was easy to break it down into mere fibers. I squeezed out as much water as I could with a cheese cloth. Then laid the cheesecloth out on the table and spread out the fibers. The sun dried it back out. Then I threw the dried fibers back into the 5 gallon bucket. Filled it about half way.I used these bricks again the next spring when filling up my flower pots. Same routine. Then mixed the fibers with potting soil. Sure made keeping my plants hydrated easier because the fibers soaked up the water and did a slow release over about 3-4 days. No more watering every day. Yaaaa.I'll buy them again once I use my other bricks. Easy to store, they really are the size of a brick, but weigh next to nothing. But can fill a 5 gallon bucket half way once reconstituted, broken up, and dried. Great.

I love this stuff, it is perfect for my needs. I use it in my corn snake's enclosure. It filled my 40gal long with about four inches of substrate plus a little more to put on top of one of her hides. Expands great, no hassle, but I recommend expanding it outside... It's pretty messy. I did it inside my kitchen though, and it cleaned up fine. It would also probably help to expand it in the enclosure.It holds humidity and burrows very well. I can see all her little tunnels on the sides of the tank, which is very cool. There is condensation on the glass under the dirt, but the top is fairly dry to protect against scale rot. Underground the humidity is probably 75-85%, maybe higher, and above ground I keep it between 30-60%, usually 30-40% on the cool side and 50-60% on the warm side. So basically, my snake can choose to be anywhere from 30% humidity to 85% humidity. I'm looking forward to her first shed so I can see how that helps! Her old enclosure really only has 30-50%, which is technically fine but would lead to incomplete shedding.I also have a ball python on a different brand of coco fiber (the fancy kind, I think it's the repti-chip brand) and honestly, I prefer this better. Cheap, clean, simple to use, no hassle. I may try using it on an arid species, but I'll have to let it air out for a long, long time. Plus, I have the option of putting plants in, which most reptile coco fiber would be difficult to use for that.I didn't even know my corn snake enjoyed burrowing until I got this!

Great product

If you want field capacity hydrated coir (little to no water dripping when you squeeze a fist full of it), then soak 1 brick in 14 cups water. Works best and fasted with boiling water in a bucket with a tight lid. Will be ready in about 4 or 5 hours and will be only warm to touch, without having to do any additional mixing.

This product is ok but far from great. Lots of white fibrous materials thru out all blocks had to go thru all the blocks by hand to pull materials from the product. I have since moved on to another product since this is also hard to get on here.

The media could not be loaded.  Roots can actually breath

Went to home depot to grab a 50 lb bag of play sand, and was going to do a 50% mix with another medium like topsoil or peat moss, but after a quick google learned about coco coir. HD had this brand by a 3rd party seller, so I just ordered off amazon instead (was better cost per unit too).It arrived 1-2 days later, took out a brick and placed it in a clear storage tote I got from walmart for $10, added maybe 3/4 gallon and had fun watching the brick soak up all the water & grow.After i broke the brick apart and mixed it evenly, added 50% of the play sand, now I have this amazing medium for my arborvitae cuttings. No regrets, very happy with this purchase

Each of the 6 bricks they send is at least a gallon by itself, once hydrated in a 1.5-2 gallon bucket. So makes 6, not just 2 gallons. Great for starting seeds and as a medium for ferns, cycads, bromeliads, orchids, etc.
