those plants look to far away from the light, i'm using 2x 125w envirolite and i've got them 1.5 inches away this really makes a diffrence,if your familiar with the inverse square law, you will know that twice the distance means 4 time as powerful.So if you put them twice as close, wich i think you could squeeze, you'll be getting 4 times as much light.This is needed when only using a 125 envirolite, it might also explain the small size for there age(sorry to piss on your fire)but apart from that looking good, keep it up.
