How to Use False Bottom Prep Rinse with dechlorinated tap water before use. to remove dust. Place a 2-3 inch layer as the drainage layer in a vivarium. Make sure your false bottom layer is flat and deep enough so that water never rises up past the substrate barrier and substrate, as this will quickly result in a saturated, sopping wet mess that is unhealthy both for plants and animals. Setting Up a Bioactive Vivarium Step 1 False Bottom works best when used with ABG Mix, Substrate Barrier, Sphagnum Moss, and Leaf Litter. Step 2 Add focal points like wood and hides Step 3 Tuck plants around the decor with tall plants in the back and shorter plants in the front. Step 4 Springtails and isopods are small insects that eat waste, dead plant matter, and mold. Step 5 The vivarium is ready for Dart Frogs, or other pets that like low ventilation and high humidity.

Review: Perfect! - Edited with update after two days: You can see how happy the plants are! Added 3rd picture. The one in the corner has stood straight up and looks brighter! All of them have taken to their new home just fine! I'll be leaving this review on all the products I bought. Above and beyond happy. Bought the plants with the 10 qt substrate and the false bottom layer. Amazing quality on the substrate. You could see it before I even pulled it out of the box how good it was going to be! Plants are beautiful. One plant had a tiny brown on an inside of one leaf. Nothing a few days help won't fix! They smell great! And we're packaged very nicely. There was barely any soil that spilled inside their packages. This is for my 6 month old gecko who finally gets his big boy home. I have. 4 year old that I went with a live plant set up about two years ago through Petsmart and a local nursery. Between the false bottom, substrate and searching forever through a nursery for 4 different plants. I literally spent half the amount of money with you guys!! And I worked for Petsmart at the time so the includes the employee discount. I almost want another reptile so I can buy more from you! So glad I found you guys! And it's not like I had to wait. It took technically just over a day for the layers. Plants were suppose to be about 10 days. They came two days early! Thanks again! Word will be speed for sure! Review: Exactly what I needed! Humidity booster - I'm using this the first time. I need to increase the humidity in my plants and I am also trying to revive an orchid. So far its working great! I wish the bad was resealable but it does fit in a gallon zip lock bag ## Features - FALSE BOTTOM or drainage layer great for automatically misted vivariums with live plants - INCREASES HUMIDITY in your vivarium by creating a place where excess water can be stored - FIRST STEP in a bioactive terrarium that prevents soggy soil - ENVIRONMENTALLY FRIENDLY since clay is an abundant resource, has a long life span, and can be added to the garden when spent - MORE BIOACTIVE SUPPLIES from Josh’s Frogs!

Humidity booster *by K***R on January 31, 2026* I'm using this the first time. I need to increase the humidity in my plants and I am also trying to revive an orchid. So far its working great! I wish the bad was resealable but it does fit in a gallon zip lock bag ### ⭐⭐⭐⭐⭐ lightweight and no breakage with minimal "dust" *by M***A on October 11, 2023* I have 2 18x18x24 bioactive, tropical vivariums for crested geckos. I used these for the drainage layer and they work well and are much lighter in weight than the lava rock I initially planned to use. Bioactive vivariums are heavy in and of themselves so being able to use these to lighten the weight was great. The packaging was secure, the expanded clay balls (leca) were fully formed and needed only minimal rinsing to get rid of the "dust." One 5-quart bag per vivarium was exactly the right amount. I've been using them for a short time but they appear to work very well so far. ## Frequently Bought Together - Josh's Frogs False Bottom - LECA Expanded Clay Pebbles (5 Quarts) - Josh's Frogs Terrarium Substrate Barrier (24"x18") - Josh's Frogs ABG Mix Tropical Plant Soil & Bioactive Terrarium Vivarium Substrate (4 Quart/1 Gallon) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/24357527-joshs-frogs-false-bottom-leca-expanded-clay-pebbles-4-quarts](https://www.desertcart.co.uk/products/24357527-joshs-frogs-false-bottom-leca-expanded-clay-pebbles-4-quarts) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-06*
