I've done pretty much every type of media and grow set up out there and have circled back to dirt. For me it is the easiest of all the methods. Yes, it doesn't have the growth rates of DWC or Hydro but I also don't have to deal with rising or dropping EC, root rot(for the most part) or any of the other issues that water grown plants have to deal with.
I get that some people just can't seem to wrap their head around growing in dirt but it still perplexes me as to why. For me it is WAY simpler in regard to having to attend to it. In DWC you have to continually fiddle with EC and stuff whereas in dirt you water it into the soil and the soil does the rest.
Not knocking DWC as I've had many excellent harvests with this method but, again, I'm lazy so dirt is a good medium for me.

I'm going to assume that the room your DIY tent is in can go totally black when you shut off the lights? Otherwise, you're going to have a light leak problem but you should know this from running DWC/Hydro.
Did you use Auto seeds? That's what they look like to me.
What size and power rating light are you using? Same question on the side lighting.
Just a suggestion but when I've made my own tents using PVC I like to use 3 way corner fittings for a more rigid structure, running T's along both sides, top and bottom so that I can make crossbars for both better structure rigidity and a place to hang things off of. If the tent is on the larger side I'll run T's on the vertical poles so I can add more straight lines and hang stuff like fans and other equipment off of it.
Of course this was in the early years when tents were exorbitantly expensive. Nowadays I can find 2 x 2 x 4 tents for around $40 so I just don't bother anymore.
The radient barrier you're using for the walls is a good insulator, but its reflective properties aren't quite as good as a white surface like
Panda Film. If reflectance was one of the reasons for using this material I would add a layer of the
panda film on the inside. The
panda film can also wrap the entire interior to also include covering your floor. As you probably know, carpet, when or if it gets wet can be a PITA along with it being able to harbor bugs and things.
Also, if you are going to be using a tent of that size I would limit the plant count to no more than 2 and up the pot size to, at most, 5 gallon as it looks like your space won't accommodate anything more than that but the extra biomass in the pot will help in feeding your girls along with your not having to water as often. I'm a synthganic grower so I use organic based soil with synthetic nutrients.
Are the computer fans both blowing air in the same direction or is one pulling air in and one pulling air out?
I noticed the temp gauge but didn't see a dedicated hygrometer. I would suggest you pick one up to at least have a baseline of the environmental conditions your girls are in.
I like your DIY spirit but if you're going to do this on a regular basis there are better ways of getting more bang for your buck on a budget along with improving your harvest yields. If you'v e been doing hydro all of this should not be new to you. I'm guessing this was more an experiment than anything else? If you want help in properly setting up a dirt run I'm more than happy to give you suggestions on your next run if you choose to go that way.
Good Luck Bro!
