Harvest after 15 days, anybody in freshwater I've try to let grow for more then 14 days. Best harvest of all, may try more days next time. Nitrate are still around 5ppm and phosphate at 1 ppm

Let's hear it for growth-through-glass
Alex - great stuff. I usually get about twice that amount in 7 days with a waterfall type scrubber but my nitrates are hanging around 20-30ppm. I totally think I could go 14 days or even longer without cleaning. This algae sticks like glue, however I dont know what the effectiveness of the algae is once you have a thick growth. Is it the growth itself that uses more nutrients or would having a 7+ day growth consume more nutrients daily????
It's the growth that consumes nutrients. However, the big bottleneck is self-shading, especially with dark growth... causes the lower layers to not only stop growing, but die and let go.
my seachem test don't detect any nitrate now but my phosphate are at 2 ppm.
Needs stronger scrubbing then.
I'm alrealdy at 18/6 hours could I increase hour or I need more light or bigger screen.
You could try 20 hours. Also could paint the inside of the light box white.
Any anything to direct more light to the back side of the screen would help.
I've already a reflector , I will try 2 jours more ans see!
You are likely nitrate limited. P will continue to rise. Try testing Potassium, and dosing that if it is below 400ppm. Get the Salifert Potassium test kit and the Brightwell Potassion for dosing, if you can.
