help!!! quick question

What watts are best for finall stages of budding 250 350 450 or 650 or 800 with making the tricom turn off white and auburn??

as many watts as you can give her

I use 50W/sq ft.

I have a 4X8 (32sq ft) tent with 1600W HID. For flower I run 2 X 600W HPS and 1 X 400W MH. For Veg it's 2 X600W MH and 1 X 400W HPS.

Time makes the trichs change colour.

Hope this helps
