Aloha ElvisG.

Nevah bought a grow tent, but I've built a few.

Scissors, tape, and bubble-mylar are all you really need.
If you expect to hang fans and lights, you'll also need a frame.

No want horse bumpin into cart inna dark, so...

How much room you got to play with and what equipment have you gathered so far?
