Shameless plug for a really cool workshop. Planted Glass Boxes is hosting an awesome terrarium workshop. There is a prerecorded video portion, and then live Zoom meetings to discuss and ask questions. I've really enjoyed the workshop so far, and the first two live sessions were a great chance to meet other people interested in starting up terrariums and growing plants. The prerecorded session goes over a lot of the nitty gritty about designing and building terrarium (especially very large ones) and how to think about the "life-support" systems and planting. If you don't follow him on Instagram or Facebook, I really recommend checking it out. He has been around for quite a while and makes some truly incredible naturalistic terraria where he grows a number of miniature orchids and aroids. Below are some photos of his current tanks, and some of the orchids he's got growing in them. If you need an added incentive, all the participants get a coupon code for Ecuagenera! If you're interested, you can email him at [email protected], or message him on Facebook or Instagram.
