The vertical space issue is a concern for me but I never did micro grows, someone with more experience may have some valid input. The space between the light and the plant has to be factored in. Lets say you have the LED panel 6 inches away and pulled up as high as possible, and you have the DWC totes on the bottom, how many inches is left for the plant? You plan to scrog it?
It seems like stealth is a priority. If this is due to legal reasons and not just a landlord one needs to weigh the risk vs. reward. That said, here is my question to you. (If the legal issues don't apply then just ignore this...)
How much do you think you will pull of out that space with the plant having to be so small? Is it worth the legal risk for such a small amount of weed? Add in the DWC and you may fight root rot and not get anything. I dunno, just seems like one would have the weight on their shoulders of growing where it's not legal, but what for? How much would be invested in the setup?
Please don't take this the wrong way, I am definitely not trying to be a dick. I just want to be real about the expectations. I am here to help however I can even though I am not in my comfort zone lol.
