My plan is to use two 4' by 4' Palram Plant Inn greenhouses as my indoor closed chamber. I've assembled the first one. The greenhouses are $300 each on Amazon with free shipping.
There are four drain holes.
I'm covering the drain holes with plant fabric and sealing that with aluminum duct tape. I'm covering the metal interior sides with a solar heating pool cover and also sealing with the same tape. This is the heat and water resistant stuff used in plumbing and duct work. I've also attached a container of waterless hand soap (with a 3M Command strip) to the exterior wall. The walls are UV resistant polycarbonate.
I will update with more pictures as I progress with substrate,plants,decor, lighting, etc.
