Default Polyester Growing Medium

This is my first post so sorry if it's in the incorrect section(I didn't see much regarding this using the search results) . I'm wondering if just regular Polyester fabric / poly-blend would be sufficient as a growth medium?
Hygrolons website states it's just Polyetylentereftalat (Polyethylene terephthalate and nylon inside). I blended up some moss and applied it to a microfiber towel (80% polyester 20%nylon{polyamide}) as a test and it's growing fantastically. The poly / nylon blend doesn't seem to mold, smell, has a neutral ph/inert, and from everything I've been reading/seeing it doesn't seem to be toxic or leach anything from it. Also there's a fabric i've seen around that seems incredibly similar to hygrolon called "3d air mesh" that's cheap and easy to source. Have any of you used this as a substitution? Thankyou

Nice find. I wasn't too happy with hygrolon. You have to constantly spray it to keep moist, you need to use big, single pieces and it doesn't wick water as well as I was expecting. Also any exposed hygrolon looks unnatural. It stayed much dryer than I was hoping.

I may try the spacer mesh for some pingulicula or something outside a vivarium.

I'm kind of torn on whether to use natural (wood, fern panels etc) or synthetics( poly fabric, foam etc) for my vivarium build.

honestly whatever you prefer. synthetics can be 'cleaner' looking and are easier to apply than great stuff foam. plus great stuff can expand and eat up a lot of tank volume. I've used both hygrolon and cork/great stuff in the same tank.

I'd be curious to try spyra from glassboxtropicals and line 3 sides of a tank with it. talk about a thin but functional background(if it works)

I posted this on another thread as well. Spacer mesh with a great discount. Hygrolon and similar materials are not meant to simply absorb water and stay wet that way. You are using it incorrectly if you are doing it that way, misting will not keep it damp long at all, it is a wicking fabric. You want a water source either below, or better yet, above in which you leave strands submerged into water to keep it wet and self water.

Exactly right. If you carry it right down into your drainage layer, that helps a lot. If it's just up in the air, you need to hit it with some water at least maybe 3x/day to keep established moss happy. Now to start moss, oh boy. More water more often! Ha ha. For that, I've done recirculating drip walls using airline tubing I perforated with a torch-heated sewing needle. I siliconed the tubing right up under the viv rim, and used a crappy little Aqua-Lifter to run water through it. The key is to have water coming out in more than just a couple of spots, that tubing really needs to be poked up to thoroughly, evenly wet the hygrolon and avoid dry spots. Dry spots = no moss started.

On the other hand, for plants that hate wet feet, hygrolon is just wonderful. You gotta pick the right tool for the job. Which means you gotta understand the job, and the tools.

good luck!
