It looks great.
You could also try having a break in the middle of the day for about an hour, where the ligths go off. This can interfere with algae growth and may help prevent it slightly. It is known as a siesta. Migth help...

Hi Mike, thanks for the compliment!! Makes it feel worth it despite all the problems... Should have added I have once again introduced a two hour siesta so lights on 9:30, off 14:30 on 16:30 off 21:30 - total of 10hrs
Am introducing 60 fast growing stems this week, should help!!
