I still can't get past the fact that your carpet is growing so well with CFL's.
Idk if you're still considering the jump to LED's but when I did it in my 40B, it was outrageous. I know everyone says that but after personally experiencing it, it was well worth it. My tank turned into a freakin madhouse jungle in literally a month. A lot more maintenance required but great end results if you go that route.
Unfortunately, life happened and I neglected the tank for a month and it completely fell apart. Had to toss half my plants and ultimately ditched the tank altogether.
I did my first scape with LED's, I find them more vibrant with extra-pop compared to CFLs.
Lighting is a weird issue for me, I been trying to find the right spectrum, intensity and photo-peroid with no luck. My plants truly did not care, my water parameters had a bigger effect.
I believe you can grow plants in a wide number of spectrums as long as the intensity is right. You make up for the lack of spectrum (red or blue) with having a higher intensity of light.
It's like having a light that looks dim to the eyes but peaks in spectrum area that plants can use most. I'm also starting to think that maybe the 'blue' range is "where it's at".
I'm thinking higher kelvins and a peak in blue (400 - 450 nm) with a modest level of red (600 nm) could be the sweet spot.
On a side note, a while back I went out and brought full spectrum CFL made for seasonal depression (does that even exist?) and it had no noticeable effect. I had some BGA but I think it came with the new plants, BGA disappear with EM treatment but I also went back to old house-hold CFL, so I don't know.
Aquatic Plants are weird, high light is great if you can control it, I'm going try going low light with high co2/lean fertilizers.
High light/High Co2/High Fertilizers works, I tired it and yes it works, but I'm going to see with the other side can offer.
Everything in this scape is done with the same bulbs you use in your kitchen and lamps.
