I've recently got into mosses after receiving small portions of about 14 varieties from a friend as a bonus from a purchase. When they arrived I wasn't exactly sure what to do with them as before this I had only ever grown the basics (eg. Java Moss, Peacock Moss, Flame Moss, etc.) and all of a sudden I have rare mosses like F. splachnobryoides and F. zippelianus just sitting in clip-seal bags on my dining room table. Suffice to say I had a little problem as my tanks were full to the brim with other stuff, and as a stickler for quarantine I wasn't going to have them sharing the same tank. A lot of the mosses also needed high light, low temperatures and CO2. So I began thinking... and thinking... and thinking. And eventually I came up with an ingenious idea to give them high light, easy access to CO2, low temperatures and all the other things they needed, all while keeping them separate from one-another.
I decided on growing them emerse (as I have had luck with Echinodorus and Cryptocorynes that way in the past). However, I wasn't too keen on using the soil mixes I had used before as they always absorbed too much water and ended up covering the medium in algae, so knowing this I decided on perlite instead and I would be mindful to keep the liquid level a lot lower than the top of the perlite to avoid algae potentially covering the mosses. Be mindful your perlite cannot fall out of the pot, however, as the pot I used had large holes on the bottom of it (I used filter wool to plug them). For extra growing help I decided to switch out water (which I had used when growing plants emerse in the past) for BioJuice (a seaweed mix for hydroponic use which promotes vegetative growth, not flowering or root growth like most) to use as the liquid, and for each pot which a moss to be contained inside a bag for humidity which I then put onto my verandah in a place where it would not be too hot, but would also get a decent amount of sunlight with the moss laid out on top of the perlite.
This'll be a work in progress. It's not too clear now but I'll work on that later today and into the future. Better photos will come, don't worry!

This one is already growing after about a week.
