- Tulips
High transpiration rates are achieved with the use of a 14 watt florescent bulb that hangs 8 inches over the container 12 hours a day. After the initial watering and misting of the plant leaves, the terrarium is kept completely enclosed. When the plants transpire the moisture collects on the sides and lid of the container, condenses, and falls back onto the plant roots and moss layer. One week after the initial setup a fan (80 mm PC fan that can be salvaged from computer bases) is installed on one side of the terrarium and an air output valve is installed on the other side (made from 1 foot long pieces (2x) of PVC pipe (3/8" piece with holes drilled into it and capped on one end and a 1.5" piece to fit over the piece with the holes). This way, the amount of clean air outflow can be controlled by the inhabitant of the personal breathing zone the terrarium serves. The fan used in this model has 3 speeds and is powered by a 12 volt battery (re-chargeable is preferred). The maximum speed is 2600 RPM with 34 CFM outflow at that speed. When the breathing space is known to be highly toxic, the fan can be put on high and the air output pipe can be opened fully. After the fresh air has been emitted, the system must be enclosed again with a sheet of plastic over the fan opening and by covering the holes in the air output pipe to keep the system working. This model should be effective in removing toxins, especially formaldehyde and benzene, with little maintenance except occasional misting with a spray bottle if it dries out from using the filtered air.
After 1 week we added this fan as well as the PVC pipe, images below:

Thanks for pointing out towards over the air purification process. This would be very helpful.
