But I'm using GE Fresh & Saltwater Aqua bulbs... 5, 24" bulbs and 2, 18" bulbs... no ballasts. Plants are growing in a 55 gallon aquarium with air tight, custom-made hood. 5 of the bulbs are installed on that hood with plexi-glass covering them (lights are enclosed in the hood) and 2 computer fans exhausting the heat from those lights. (The way I have it setup, there is very little heat coming from those 5 fixtures, if any at all.) I do have a heat lamp (thats how im getting my heat in there) placed on the OUTSIDE of the aquarium facing in next to the plants, NOT on them. I have the 2 18" lights hanging on the side of the aquarium, hitting the plants from the side. I have 2 computer fans that run on a timer at night to exhaust heat and CO2.

Does anyone know why the tips are bent down on the new growth, there is no yellowing or browning, the tips are just pointing down...?
I'm very curious about your Saltwater aqua lights. Are these the 9325K light spectrum? I'm having a hard time finding exactly the ones you have. From what I read on that spectrum and aquarium use was that it had deeper light penetration I'm assuming in water. I once thought about an aquarium grow so this is all very interesting to me. Is the aquarium glass or plastic? And what's the ambient temp of the room? Also what kind of intake do you have? Cool setup on the hood btw.
