#leca

My first plant in semihydro. They are small Schlumbergera cuttings. I also have a big plant growing in soil, I thought I try these ones in leca

Behold: my little transition table/jungle! I’m about a month into transitioning my indoor plants to semi hydroponics: ZZ, Hoya Australis, orchid, snake plant (Zeylanica and Laurentii), Schefflera arboricola, pothos (golden and neon), monstera deliciosa, alocasia scalprum, and hopefully starting the alocasia stingray next weekend. I also have a pilea peperomiodes that I accidentally decapitated when trying to get some lower leaf cuttings… it’s sitting in a rooting nutrient solution with an air stone and already has some roots! Once they get longer/develop secondary roots I’ll plop it in some LECA. It has been so satisfying watching the fuzzy new roots develop :D I’m not confident that the Hoya is going to make it but it was a freebie that came along with some wall-mounted planters I found on Craigslist so I will try not to be too upset if it doesn’t work out. It feels good to have a new hobby

Let's start with the first LECA. Clay is formed from hydrous aluminum phyllosilicates, which are minerals. Although clay did exist before Cyanobacteria did, the atmospheric O2 which Cyanobacteria created causing the Great Oxygenation Even did cause an increase in the amount of clay on Earth, as Clay contains Oxygen and cannot be formed without it. Lightweight Expanded Clay Aggregate however could not exist without Cyanobacteria, because all organisms capable of creating the rotary kilns needed to produce it breathe atmospheric O2 as well, almost all of which was produced by Cyanobacteria in the aforementioned GOE. I think this ask might be talking about the other LECA though. The Last Eukaryotic Common Ancestor would exist without Cyanobacteria. This organism, which lived about 2.2 billion years ago, was the ancestor of all Eukaryotes and was formed through the symbiogenesis of an archaeon and a bacterium. Although this did happen at the same time as the GOE, neither the archaeon nor the bacterium which came to form the first eukaryote exclusively breathed O2. The archaeon was likely anerobic (did not breathe O2), and the bacterium was facultatively aerobic (could breathe O2, but didn't have to). It is worth nothing however, that most modern Eukaryotes do exclusively breathe the O2 produced by Cyanobacteria, and that quite a portion of modern Eukaryotes actually contain Cyanobacteria (although LECA did not).
