Those two things alone will make your plant look like that. Also , what kind of "plant" bulbs are you using? Are you using "grow bulbs?" I have found the 6500K color temperature DAYLIGHT bulbs work much better as I think they are brighter and have a better color temperature for vegetative growth.

And by exhausting the heat from the room, probably by just leaving the room open will decrease your water temps as well giving you better results in what might seem as slow growth.

Like headshake asked, "Are you running a sealed room?"

And I'm curious as to what kind of ballasts you are running.


First off, I Aapreciate all the responses...

I was assuming it was ph lockout so i have been keeping the ph at 5.8. From what I've been reading though, with supplemental CO2, 85 to low 90's are alright, plus the plants seem to love it. 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...?
