Here's what you need to make a cheap, yet small, grow box with lighting, ventilation, and some carbon scrubbing. Great for tomato and chili plants of course.
Materials:
1 large rubbermaid container
1 large roll metal repair tape
1 42watt CFL
1 lightbulb socket
1 timer
1 trueair odor eliminating fan unit
1 roll masking tape
1 plastic bowl that fits the front of the Truair unit
2 feet pvc pipe
3 pvc elbows
1 pvc slight angle elbow (like 45 degree or less)
Trace the PVC pipe on the side of the container, near the bottom, and also on the top corner, cut holes (2 total) using a small sharp knife. The bottom will be air intake (passive) and the top will be output via suction. The top will have the Trueair unit attatched to it externally. Cut two sections of PVC pipe so that you can join the four elbows, with two elbows inside and two outside, witout leaving any gap so that the bases of the elbows are flush with the container walls. The slight elbow will be on the outside on the top, to connect with the Truair unit. So now when you have an hour to kill, get that aluminum tape and tape every square inch of the inside of the container, including the underside of the lid and the bottom of the bottom part, to block light from going through the thin plastic walls, and to make nice reflective walls. Now get the lid and cut an X slit and push the cord of the light socket through it so that the bottom of the light socket is flush with the underside of the lid, then secure it by taping the the cord to the top side of the lid. When this is complete the bulb should hang directly downwards towards the floor. Now the potentially tricky part, match the plastic bowl up with the front (air intake side) of the Truair unit, make sure it'll create a seal, some cutting and fitting may be needed. When that's OK, cut a hole for maybe eight inches of PVC pipe in the center of the bowl, secure it with masking tape to create a good airtight seal, then attach that to the Truair and create an airtight seal. Now you should be able to stick that onto the outside slight elbow, and it will suck air out of the container. I presume that it'll be possible to start maybe three plants in this unit, and they'll need to be LSTd to prevent them from touching the light, and perhaps a screen could be put around the light.
