I submitted Revision 0 plans to a number of forums and Reddit. The general feedback was more light and thicker PVC. I decided to add a hanging panel to the ceiling, to more evenly distribute the weight of the lights and allow for fine tuning their placement. I also remeasured the space and tried to leave room for a dry/cure cabinet to be installed in the space as well. I added in electrical, ventilation and plumbing. My plan for using Velcro along the edges was supported by community feedback. The lights will be 400W and ventilation is 6″ diameter.
