with 16 I would go with 2 of the 400 watt. Kind of spreads the light out more and those diamonds, I have never seen, the others are just as good.

Interesting in a good way. I would like to see it up close so I could maybe copy it in some way. I don't have the space so I would have to modd it.

Get the bluelab CF meter it will last and the hobby PH meter some calibration fluid for the PH meter. At least a litre of PH up and down. I would suggest General Hydroponics Flora 3 part. A litre of each to start. What I do not see is cal-mag plus. You need it or something like it if you use R/O or distilled water or poor water.
