Show HN: Oasis – An open-source, 3D-printed smart terrarium

I don’t think LEDs work. Don’t you need full spectrum lighting for a terrarium?

Full spectrum would be more optimal, but the 5700k "daylight" LEDs I'm using still work very well. They're probably lacking a bit on the red end of the spectrum compared to a full-spectrum light, but otherwise they cover the photosynthetic range pretty well. See page 19 of the datasheet for the LED spectrum: https://downloads.cree-led.com/files/ds/x/XLamp-XTE.pdf. And here for some decent general info: https://www.neherpetoculture.com/vivariumlighting101.

Anecdotally, I've successfully grown a range of plants in these including mosses, ferns, and orchids.

Thanks!

I'd recommend @SerpaDesign on YouTube as a great source of info on terrariums - he's got quite a few videos that cover this, but here's one to start: https://www.youtube.com/watch?v=7Lg4tzkHgVo&t=1s&ab_channel=....

The main thing to keep in mind is that terrariums are high-humidity environments, so plants like mosses, ferns, and orchids will do well. Plants that prefer a dryer climate like succulents and cacti will not do well.

Another consideration is lighting - some plants want more, some want less. This terrarium is capable of fairly high light output, but can also be set to any level you want. However, you'll want to select plants that want a similar amount of light so they can co-exist with the same light settings.

Ive always wanted to do something like this. Nice!
