Light is not getting into the tent now.AC INfinity sells black ducting in multiple sizes. Should reduce the reflection
I replaced the old venting with the dryer venting for the better intake air coming in and mixing in the tent better.I may be missing something here and correct me if I am wrong, but why change to AC Infinity black ducting, like for the outside is what meant? I wouldn’t imagine changing the inside, as ya would want the silver reflection (why more thinking outside the tent ducting)
Edit: ok I kinda see what’s going on here, after reviewing pic a second time, that’s and outlet from the tent in the first pic,
I got the smaller size for space inside the tent. It did accomplish that job. It's more stable and the mix is better measured at different levels.
Negative, as expected, is that is does suck the sides in a bit, but lessened when the fan was adjusted. 6in would be a good compromise, fan is 8in.
Lung room does need to be slightly cooler,but that is most likely from a better mix in the tent than the lower/restricted airflow.
