Plants are looking great,
@Costanza. I wouldn't let a little light leak in the tent bother you.
I'm sure it won't bother the plants at all either. I've never had issues from it and know people run tents side by side with leaks in both. Really though, I wish more manufacturers would cover the damn zippers with a flap, it's common sense. Also wish that they'd stop using velcro for windows and vents.
And you're making me want some of those self watering things too. Looks like they're sold out atm though.
The only issue for me would be that my 1 part nutrients might not jam well with it because the salts fall out of suspension. I guess the other issue is there's no runoff ever. Probably fine if your nutrients let you feed plain water occasionally. But it sounds like the plants are basically draining the res daily, which would at least get rid of the first issue. Really, anything to get away from the pain in the ass of watering a bit at a time until saturation and draining drip trays.
