t5 hydro (first hydroponic grow)

OK, so I've lurked on here for a while and recently decided to start posting/asking your guys help or opinions.
I built a :2'×4'×4.5' grow tent
With 170 cfm 4" exhaust fan and passive air intake.
18.5"× 4' 6 bulb t5

So I have a 27 gallon tote with 12 gals of water. 6 net cups each. How does this sound to you guys? Temps average around 75-85 and humidity around 35.
The grow started from bag seed and was planted 1 week ago. Each is almost an inch tall and has its first set of serrated leaves. Any advice on things I need to add or take away? I also plan this to be a scrog...

Outside the tote I have a 60 gph air pump running to 2 10" strip air stones... Inside the tote I have a 60 gph fountain pump with a 8 way splitter. I have a second 60 gph air pump running into the fountain pumps up stem(so I have a lot of air in the steady drip in my roots).

I'm a noob so I could be wrong, but I think if that's aluminum foil in the pics I'd remove it. My research told me it gets "hot spots".

Good luck, enjoyed your pics.

ok so i see i got close to 200 views though noone has anything to say... ? does this mean im going in the right direction? well anyhow today is day 14..... the biggest plant is about 3 inches from the top of rockwool to top of new growth. A question I have is, is it normal for the plant to have 4 sets of alternating serated leaves and only be week 2 and 3 inches tall? ..... that was last night. this morning i woke up to catch my fuzzbutt wrecking my grow tent. i saved them all and no real damage since none of them have died and all look to be doing well. ill attach pics maybe you guys can tell me if you think they will last
