grass floor, foggy, no tables, just pots on the ground, constant supply of water, no ants, winter heating
as for things that i find essential...
an easily accessible supply of water!
way to heat/cool the greenhouse
I want a tri-house, so to speak. It will be about 24x12 when finished and will consist of two halves. The first half I want to build this year and it will be strictly for cactus, succulents and plants that require a dormancy but cannot get soaked by nature. It will be a mostly natural house; no ac, just maybe some roof ventilation and a few fans for air flow. It will have a roof that slants to the where the entrance will be. Highest point of roof will be maybe 8-9' and the lowest, 6-7'.
An opposing side for carnivores will be added to the rear of the cactus house VIA a flange that I will purposefully build on the first one. This one will be climate controlled with a misting system and fans. The flange between the two will form a HL chamber for me to grow helis and such under some natural and supplemental lighting. An AC will be forced through from the outside to keep it nice and cool. I'm thinking about putting a fan through the wall leading towards the carnivore side that can toggle on as needed in case things get really hot.
