The new viparspectra xs2000 seems to be working well so far , I really like the ability to dim it when I am tending the garden as it is incredibly bright even when wearing shades.
Fastbuds Gelato seems to be off to a good start and appears to be loving the new light , which I have at 50% power right now and 28"above the plant. I will be moving it a little closer this week and see how it goes.
You can check out all their lights at

And they tell me you can use the code GDVIP for a discount
Also look them up on Facebook

I see that you are keeping the bottom of the pot off the ground using a metal rack. I'm doing the same thing as I am guessing it improves air flow to the soil, prevents the pot from sitting in a pool of run-off and makes it easier to collect the run off for TDS measurements?
