Your plants look fine to me. What strain is that? Bagseed?

I do have a few comments/questions about your setup, if you'll indulge me?

Are you using any nutes right now? (Shouldn't be, if you are. After 2 weeks is when you start, I believe.)

Do you have a way of checking the PH? Humidity? Temps?

Your PC fans look like they are using 2 seperate adapters. What are the ratings for those adapters? PC fans use very little wattage, and have low ratings overall... one adapter (with low/matching ratings, as well) should be plenty, unless you have them on seperate timers.

It also seems that you're using aluminum tape(?) to secure the wire connections you've made. I would definitely suggest using wire nuts, to avoid a fire.

Are you using aluminum foil or mylar to cover the interior? I don't use either myself, but I think I read somewhere (someone correct me if im wrong), that aluminum foil absorbs light. Maybe thats mirrors?

Setup looks good though. Have you figured out where you'll put them when they get bigger? You'll need lots of room! I started out in a 55-gal aquarium, but out-grew it FAST!
