Mr Miagi
Veins are flowing with SW, now going back to FW!
I only have a single tube lighting fixture. 30W which is not adequate. A planned upgrade to twin tubes is in the works, but not till atleast late next month.
I dont use any co2 and never have. Which is a bummer really, cause my plants would probably grow ten fold if i did. Another project in the works..
But i should be getting a co2 system whithin the next month. I do use ferts. Tabs and liquid. Seachem to be exact. Once a week normaly and my root tabs last 3-4 months.
Today:

It looks much better than before! 
with bo luck.
