One of the reasons to grow small plants in a terrarium will be to supply humidity than could be seen in most homes to growing conditions. Completely closed terrariums retain high levels of moisture and require watering, but there’s also probability of plant diseases developing in the stagnant atmosphere. A good compromise can be achieved by establishing a terrarium with venting to supply air movement and a misting system to supply the humidity.
Reservoir and Vacuum Installation
Drill a hole in the side of the painter’s bucket close to the base. The hole’s size will rely on the bulkhead fitting. A 5/8-inch or 9/16-inch drill bit should function with fittings intended for 1/4-inch tubing.
Insert the bulkhead fitting to the pit, with the O-ring on the surface between the bulkhead plug and the bucket. Tighten the nut which came to hold it.
Cut short lengths of tube, with the utility knife, to connect the bulkhead fitting. When using a ball valve to turn the water off and on, connect it between the reservoir and the pump.
Publish an electronic timer to the pump system following manufacturer directions for the version of timer.
Installing Mist Nozzles
Produce holes in the lid of the terrarium for the misting nozzles. If the lid is plastic or glass, make sure the lid is padded to reduce vibrations before drilling the holes. For screen lids, cut holes of the size that is correct. The size of the holes will depend on the type of misting nozzle you choose
Disassemble the misting nozzles carefully. Simply separate the parts of this misting assembly which will connect the nozzles via holes in the lid. Do not unscrew the tip of the nozzle. Misting nozzles are set to discharge water particles between 50 to 100 microns in size, and the flow speed can be altered by touching them.
Slide the bulkhead of the misting nozzle assembly through the hole and secure it. Attach to the Peak of the nozzle. Cut and measure tube together with the utility knife to attach nozzle and the T-connector to the pump.
Continue installing misting nozzles until the nozzle is attained. To complete the misting system, attach by means of a union elbow connector.
