OK Rollitup, here is your chance to utilize all the knowledge you have gathered from being on this forum, I need the elite players on this forum to help co-op setup our dispensary's grow room. Here are the measurements given to me by my friend. . I had a friend gave me a diagram, but it was miscalculated by 4 inches being so narrow we actually have a hard time walking and working through the back row. (top) none the less before this was discovered the lights were hung, the plan was executed. It works but the workspace in the back is is very limited. Here are a few pictures of the finished room The ducting on the left is a 12-12-8. the 8 was used for the ac. the other 12 is an exhaust but i have now attached the 8 to exhaust the air-cooled lights. The current setup is really inefficient because it is so hard to get to the res, which sit under the 3x6 trays ( which i last measured was about 76" x 38") lights are radiant 8s. please help with the design. I need some thing simple, productive and efficient. just looking for some ideas.
