Oh really? That's also good to know. I'll have to check the clay shop out, been needing some clay things for a while. Thanks!Actually Johny, you don't fire clay substrates. You just dry them. You don't even need to use the oven like I did. That was just because it was winter and I couldn't set it out to dry. We have a great clay supply shop referenced in that thread, right near I-25 and Sante Fe.
Little/no drainage is one physical issue... Then there's almost always "organic" fertilizer added which is actually bat, cow, other animal's excrement. That's bad for a number of reasons. Potting soil in a vivarium will also almost certainly lead to an explosion of fungus gnats as it breaks down... And it breaks down quickly.What's the disadvantages of using organic rated potting soil at warehouse stores?
edit: AeroWRX - lol I didn't realize it was you! On Dendroboard too, now?There are a few different recipes I've commonly thought of as actual ABG mix (or equivalent):
Verison 1: 2pt Tree Fern fiber, 1pt peat, 1pt charcoal, 1pt sphagnum, 2pt coco, 2 pt orchid bark
Version 2: 2pt Tree Fern fiber, 1pt peat, 1pt charcoal, 1pt sphagnum, 2pt orchid bark
Version 3: 2pt Tree Fern fiber, 1pt peat, 1pt charcoal, 2pt sphagnum, 2pt orchid bark
I personally don't see peat being a good thing. It breaks down faster than coconut fiber would, and it can compact.
Tree fern fiber is very important, since it helps keeps the soil "airy" and virtually never breaks down. Without Tree Fern fiber and orchid bark - it's not going to work like ABG mix regardless of the other ingredients. Soil must be allowed to breathe to build beneficial bacteria, support plant life, and support microfauna.
I've heard people using "organic" potting soil mixed with orchid bark, sphagnum moss, and charcoal call it "ABG equivalent". It's not! potting soil will quickly break down, and 90% of it contains other unwanted ingredients.
A good substrate should never exceed 50% of "soil" ingredient. (meaning coconut fiber, peat, or potting soil) More than 50% will get soggy very quickly. Ideally it should be around 35-25% of the mix, as it would be in ABG. The "saving money" thing goes a long way in this economy, so I completely understand people wanting to mix substrate themselves. Unfortunately the most expensive ingredients (orchid bark, sphagnum, charcoal, tree fern fiber) should make up the majority of the mix.
Charcoal = Fine/Medium grade
Orchid Bark = Fine/Medium grade (home improvement store bark works, but it's usually large grain. Zoo Med reptibark IS fine orchid bark. )
Tree Fern Fiber = Fine/Medium grade (I've heard just fine being used - but we've had good luck with both)
Coconut fiber & "Coir" = Same thing!
haha yup! Done rolling around in marijuana forums so I decided to find out what dart frog people do.Little/no drainage is one physical issue... Then there's almost always "organic" fertilizer added which is actually bat, cow, other animal's excrement. That's bad for a number of reasons.

It's simply not meant to last years. It's meant to last the size of the pot, and even then the plant would usually get repotted frequently to keep the soil fresh.
