I’ve done a couple moss terrariums with different substrates (spaghnum, clay, and stratum) trying to decide which one I liked most, and the answer is sub stratum! Everything greens up immediately, and it just becomes a healthier looking plant. Quick growth, I had a couple newly rooted cuttings that got knocked out of their planter and were very stressed and sad. I popped them in a cup with this stratum and a day later you’d never even know something happened to them! I was really worried about doing the moss bc I didn't know what to expect, moss can’t tolerate fertilizers and I know very little about ‘proper’ substrate for it. But it’s so so happy, could be due to the container as all 3 are potted a little different but I think the micronutrients or beneficial bacteria are doing their jobs, making my job much easier!! When I'm done with these other few terrariums and small guys I’m gonna start bottom and top dressing all my plants with sub stratum, or using only this sub stratum for smaller pots. It’s a very good price, compared to the name brand that’s twice as much for the same amount. There’s also a listing for 4.4lbs for $2 more than this 8.8lb bag. I just came back to buy 3 more bags, not too much more expensive than.soil nowadays, and it’s far superior in almost every way. Review: Love this stuff - Honestly some of the best substrate I've ever used. Awesome color. Nice size little rocks. Overall highly recommend. ## Features - Natural Bioactive Soil: Bioactive Volcanic Substrate offers a natural solution for terrariums, promoting a bioactive environment that supports plant and animal life - Promotes Cleanliness and Health: With its unique properties, this substrate helps maintain cleanliness and health within the terrarium, fostering a thriving ecosystem for your plants and pets - Ammonia and Odor Elimination: Bioactive Volcanic Substrate effectively eliminates ammonia and unpleasant odors, creating a more comfortable environment for terrarium inhabitants - Superb Drainage Capabilities: Featuring excellent drainage capabilities, this substrate prevents waterlogging and ensures proper moisture levels, essential for the well-being of plants and animals - Ideal for Planted Terrariums: Specifically designed for bioactive planted terrariums, Bioactive Volcanic Substrate provides the perfect foundation for lush vegetation and a diverse range of terrarium species ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B091L3QS9F | | ASIN | B091L3QS9F | | Age Range Description | All Life Stages | | Best Sellers Rank | #43,044 in Pet Supplies ( See Top 100 in Pet Supplies ) #106 in Terrarium Substrate | | Brand Name | Exo Terra | | Color | Brown | | Customer Reviews | 4.7 4.7 out of 5 stars (153) | | Date First Available | April 2, 2021 | | Date First Available | April 2, 2021 | | Directions | Follow individual packaging instructions. | | Included Components | All items listed in description. | | Item Dimensions LxWxH | 9.45 x 2.76 x 14.17 inches | | Item Package Dimensions L x W x H | 12.71 x 10.63 x 4.06 inches | | Item Weight | 4 Kilograms | | Item model number | PT3184 | | Item model number | PT3184 | | Manufacturer | Rolf C.
