I'm in same boat, looking for a doctor in canada for legal use but I would suggest making a cab grow. Look around kijiji, craigstlist, thrift store. Look for a closed cabinet.
Next look for 2 working pc fans. After you have the fans look for 2 12v cellphone charger. (Most cell phone chargers are 12v). Look on youtube how to connect the pc fan with the cell phone charger. Slice the end of the cell phone charger where it would connect to the phone. Slice the very end of the pc fan wire. I would suggest using wire slicers for the next part but a razor blade or something sharp can cut it. Next you will see 2 little wires in the wire you sliced from both the pc fan and cellphone charger. You will see red and black, or 2 different colours. You get the black wire, get the copper/ metal part and connect to the black metal wire from charger. Do the same for red wire from pc to red wire to charger. Use those orange twist things to stop electric from escaping when you conect the two. You can use electrical tape as well to connect the too but make sure the entire metal wires from the two are covered in electric tape.
Get 2 powerbars with circuit breaker. Buy those light sockets you connect to cfls. Buy atleast 3 cfl 2700k and 3 6500k. (The "k" rating is listed on the box of the lights).
Buy mylar or window shield reflector (sun reflector stuff, mylar won't be at any store so most likely go for sun window reflectors, buy enough to cover the whole inside of your cab).
Buy a simple themometer. (Spelling might be wrong, I'm a bit high).
Buy a saw or something to cut the wood, also have wood glue or nails and hammer, depending what your using.
Buy a ph testing kit. (Not needed but recommeneded, you'll need it eventually)
Buy seeds or get a bag of weed and look for seeds.
Buy a timer (not needed but helps).
Make a carbon filter (I haven't yet but there's threads on here how to)
Building time:
Get a sharpy or marker and trace the two pc fans on the cab (one near the top, one near the bottom).
Cut the marker line. Place the bottom fan blowing inside, place fan blowing outside near top (head rises).
Glue/ put a nail at the top inside for the 2 powerbars. (Lights will connect to socket and face down). (You can also create a chain connected to lower and raise lights but I haven't built yet).
Tape down wires and cut a little hole where the plugs will go through. Make sure wires are taped using ductape to cabinet so they won't move.
Cover the cabinet with your mylar/ sun reflector/ white paint.
Plug into timer/ another powerbar if need.
Post pictures to me so I can see what it turned out to look like. Also put some christmas decorations for christmas. Lol.
Ps- look at my thread northern lights grow. It'll show you mine. Mines not perfect yet, still want to build light blockers for fans and build carbon filters.
Hope that helps.
