31) shrink tubing or electrical tape (buy online)

32) 1 roll of Duct Tape

The Greenhouse Build:

A) Assemble the greenhouse (01) and place in plastic tray (10).

B) Cut the Styrofoam pool toys (11) into lengthwise halves and stuff cut halves between

sides of greenhouse (01) and plastic tray (10) for sealing up the greenhouse (01) cover

with the plastic tray (10).

C) Punch a small ¼” hole in the four top corners of the greenhouse (01) cover, and stuff a

~4 foot piece of surgical tubing (06) into each hole and seal with Styrofoam sealant (07).

D) Attach all four tubes (06) into one end of a PVC Union (09) and seal with Styrofoam

sealant (07).

E) Cut a ~6” piece of 5/8” hose (04), and stuff one end into outlet of ultrasonic (03) and

seal with Styrofoam sealant (07), and stuff the other end into the other end of the PVC

Union (09) from step (D) and seal with Styrofoam sealant (07). The ultrasonic (03) is

now hooked up to the greenhouse (01) and could be put on a timer for automated (non-

PC) control.

F) Punch a small 1” hole in the top back portion of the greenhouse (01) cover, stuff the

end of a ~4” piece of 5/8” hose (04) into the hole and seal with Styrofoam sealant (07),

and stuff the other end into a PVC Union (09) and seal with Styrofoam sealant (07).

G) Cut a ~6” piece of 5/8” hose (04), and stuff one end into outlet of cool mist (02) and

seal with Styrofoam sealant (07), and stuff the other end into a PVC Union (09) and seal

with Styrofoam sealant (07).

H) Cut a ~6 foot piece of 5/8” hose (04), and stuff one end into the other end of the PVC

Union (09) from step (G) and seal with Styrofoam sealant (07), and stuff the other end

into the other end of the PVC Union (09) from step (F) and seal with Styrofoam sealant

(07).

I) Optionally, (i) cut a hole in the top of the cool mist (02) and with the Styrofoam sealant

(07) seal the top of a plastic bottle into the hole for easy filling, (ii) cut a cut a large ~2”

hole on the front of the cool mist (02) and with the Styrofoam sealant (07) seal in a piece

of jewel case (17) for creating a window to see when the cool mist (02) needs filling, (iii)

add a aquarium heater for warm mist applications. The cool mist (02) is now hooked up

to the greenhouse (01) and could be put on a timer for automated (non-PC) control.

J) Cut the end off of the AC to DC converter (08) wiring and wire to the PC fan (05) and

seal with shrink tubing or electrical tape (30). Plug in the AC to DC converter (08) and

test the fan (05) before sealing the wires.

K) Seal the fan (05) onto the HEPA heater filter (12) using the Styrofoam sealant (07), let

dry, and cut fan out from the HEPA heater filter (12). Make sure to note the air flow

direction of the HEPA heater filter (12) and mount onto the fan (05) so that the fan (05)

will be blowing HEPA filtered air.

L) Cut a centered square-shaped hole in the top cover of the greenhouse (01) and seal in

place with Styrofoam sealant (07). Make sure that the HEPA filtered air blows into the

inside of the greenhouse (01).

M) Make two w-shaped brackets from the wire clothes hanger (13) and mount inside

greenhouse so as to support the fan (05). Add some duct tape to bottom of w brackets for

padding. Melt four holes in the corners of the 4”x4” piece of thin Plexiglass (14) and fit

over the w brackets to act as shield to keep the fan (05) from blowing directly onto the

greenhouse (01) shelves. Test the fan (05) to make sure that it causes the greenhouse

(01) to inflate. The HEPA filtered fan (05) is now hooked up to the greenhouse (01) and

could be put on a timer for automated (non-PC) control.

N) Place reptile heater (15) under plastic tray (10) and space heater (16) near greenhouse

(01). The heaters (15, 16) are now hooked up to the greenhouse (01) and could be put on

a timer or temperature switch for automated (non-PC) control.

P) Mount the light (18) over greenhouse (01). The light (18) is now hooked up to the

greenhouse (01) and could be put on a timer for automated (non-PC) control.

The greenhouse (01) build is now complete and the greenhouse (01) could be put on

timers for automated (non-PC) control.

The PC Automation Build:

A) Attach the USB controlled switch controller (19) to a USB port of the PC (27). Plug

in the RF signal boosters (21) into two different AC sockets of your house. Plug in cool

mist (02), ultrasonic (03), fan (05) and heaters (15, 16) into respective of the controlled

appliance switches (22), which are plugged into respective AC outlets. Plug in the light

(18) into the controlled light switch (23), which is plugged into an AC outlet.

B) Load the HomeSeer software (24) onto the PC (27). Configure the switches (22, 23)

in the HomeSeer software (24). At this point, the greenhouse (01) can be controlled by

the HomeSeer software (24), including manual, timed, and other modes.

C) Attach one end of the USB cable extender (26) to the THUM device (19) and mount

the THUM device (19) over the plastic shield (14) in the greenhouse (01) so that the fan

(05) blows on the THUM device (19), and attach the other end of the cable extender (26)

to another USB port of the PC (27) and load and run the included THUM device (19)

software. Test the THUM device (19) for accurate temperature and humidity readings

inside the greenhouse (01).

D) Copy the THUM HomeSeer script file (25) to the HomeSeer software (24) plug-in

directory. Configure virtual THUM temperature, humidity, and dew point devices in the

HomeSeer software (24), run the HomeSeer software (24) and ensure that the script file

(25) is working and providing temperature and humidity measurement values to the

HomeSeer software (24).

E) Create events in the HomeSeer software (24) for controlling the cool mist (02), the

ultrasonic (03), the fan (05), the heaters (15, 16), and light (18).

The greenhouse (01) can now be fully PC (27) controlled. For example, for fruiting, the

light (18) can be configured to turn on at dawn and turn off at dusk. The fan (05) can be

configured to turn on for one minute every 11 minutes. The heaters (15, 16) can be

configured to turn on and off based on the THUM device (19) temperature level

measurement of about 75 F. The ultrasonic (03) can be configured to turn on when the

THUM device (19) humidity level is below 92% RH and turn off when the RH level

reaches 93%, whereas the cool mist (02) can be configured to turn on when the THUM

device (19) humidity level is below 92% RH and turn off when the RH level reaches

95%. Using these techniques, the cool mist (02) and ultrasonic (03) can be run in a very

efficient manner, such that extra water storage tanks, etc., need not be employed.

Finally, enjoy the fruits of your labor!
