damn man, you got a major set up happening all over the place, i understand the fustration of getting all your set ups dialed in, my suggestion is to take it one by one since you have so many, you will find that once you have each area dialed in you will be stressing way less and just enjoying the grow, you got tons of variety my man excited to see them all. keep up the good work, stay safe and happy growing
That filter does help, you could maybe even lean a board there or something to kind of baffle it coming in. I hear you though, getting things set up and working just right can be frustrating but it feels so darn good when you get it just right and can sit back and watch it grow. I actually feel like I'm doing less now that I have gotten things dialed in. You have a good amount of space and a nice variety man, I like it. Have a great day man, happy growing!
