Nope...no Co2. It's been growing for about 3 months+ with just the 15 watt flourescant bulb. I was trying to save money, the bulb actually belongs on a 10 gallon, but it was all I had...lol
The only fertalizing I do is a few drops of flourish twice a week.
Yep, that's the petite that they're on.
I'll post it up tonight on the other forum...I hafta resize the images first...lol
