instructions

Poor some carbon in the mesh like "pencil cup"

just enough so the smaller cup is level with the larger cup.

Slip the smaller cup into the sock

Tuck the sock into the smaller cup holding the end of the sock. Pore in the carbon.. keep holding the end of the sock.

Now pull on the end of the sock and use your finger to guide the carbon into the space between both cups until filled.

Now pull the end of the sock over the entire filter.. twist the end of the sock at the bottom and pull it up over the end of the cup.

Now simply use duck-tape to place the filter over your exhaust fan. I used a rubber band to secure it

just another one for those of you on a budget!!!!!!

cfl reflector

How and where to cut:

Firstly, draw a plan of your cutting path on the outside of the can using a permanent marker or a wax crayon. This will aid you to get a better overview of you plan and to avoid silly mistakes on the way.

Cutting the top part of the can out needs to be done first, adjusting the opening according to the size of your bulb. You do not have to cut it exactly to shape as glue (super or high-temp hot glue) can be used to stick the reflector to the bulb ballast later on. A can opener is the preffered tool for this job. The reflector is purposely not covering the ballast to ensure good aeration and to avoid damage to the ballast components, resulting in a short circuit.

Next, you will need to cut the main part of your soda can in half using your scissors. A hole may need to be drilled first using your kitchen knife to get a good starting point for the scissors.

The inside of the can is coated with a thin plastic layer that should not cause any trouble cutting through the sheet metal. The bottom side of the can does not have to remain in place but leaving it will add stability to the reflector and enhance the reflectivity. An extra hole can be cut into the bottom as well to improve ventilation along the bulb or to connect a 50mm pc-fan to the end.

Lastly, two more cuts have to be made into the sides of the semi-circle reflector to ensure that the sides do not reflect the light back to its origin but rather focus it to where it is needed. The reflector can now be bent according to your light requirements thus making it possible to focus it directly on your plants. If your reflector does not quite fit the bulb yet you can now use glue to stick it to the ballast.

enjoy!!!
