I just got finished with the lighting of my new terrarium and Im not sure if the light is sufficient enuf. I have 2 25 watt equivelent to 100 watt floroucent compact bulbs over the top of the tank with no reflecting material on the sides or back. Is this enuf? 50watt total? I have a raff, bical, ventrat,ventricosa,coccinea,and a ceph. Is the lighting enuf for these? By the way the lights are about 5-6 inches away from the plants. Any help would be appreciated. Thanks!!!!
