first time grower need all help i can get.

i currently am growing two plants from a seeds that i got from a bag of mid. i have two 23 watt cfls and one 75 watt flourescent grow light. my plants seem to be doing fine. they are 18 days old and they are working on there fourth set of leaves. my grow space is about 2*2 i really dont know but i know it aint bigger than that. right now my biggest question is are my plants doing this good with this little light because of the small space or is this about right? i feel as though its not enough and the reasearch i been doing says the same but my plants are healthy as shit. all comments and feedback is needed. lost my phone so cant post pics but i will asap.
