@Fuel I’ve been slowly reading through your thread and wishing I had found it just a week or two earlier. Good discussions and I find your posts hilarious to read with a similar tone as my own. The idea, the implementation, the realizations of drawbacks, and whatever the next steps are. Anyway, the lung box and the light baffle are very similar to what I had planned. Good to note your lessons learned there before I build a lung box. I laugh almost every time I read “torque” in your postings, it’s not a common word to native English speakers but so much better sometimes. Also “blunt powered” air intake cracks me up every time I read it. 
@Dirt_Wizard I don’t recall you promised me anything so you don’t need to worry about it. But, I mean, I love seeds. Always welcome in my mailbox
With regards to the venting, I actually looked at one of those periscope dryer ducts when I was at Lowe’s hatching my schemes. It’s all good stuff to be aware of when you play with this sort of thing. I had decided that I felt it was too clunky to go inside my tiny tent and I could build something similar with the inlet filter integrated. I decided at the end of the day to construct a simple pink-foam filter holder/register that sits on the floor outside the left tent wall and cut my own new inlet at the bottom of the tent. Regarding building one, I can’t emphasize enough how badass that Thermopan stuff is if you are building these - the Gorilla Glue works great on it and it’d just fold up to make this duct in minutes. I’ve very familar with Coroplast and it’s nice, but the Thermopan has supplanted that in my mind for this stuff. It’s just so easy to work with. Problem is it’s somewhat costly for what it is - around a dollar per sqft shipped.
Am I correct in understanding you are linking tents outlet-to-inlet? Do you run into issues with temp/humidity this way?
I not only don’t mind, I’m happy to see you pop in. I enjoy your posts and have learned quite a bit through them.
Cheers guys, hope you all have a great day. I appreciate all the input and help!
