10 weeks old, which light spectrum

[Jayce71]

Hi, have a 10 week old G-13 Hze female, that started flowering over a week ago,
lots of little white hairs sprouting everywhere,
I'm using a Viparspectra 600, I did have it fully on blue up until last week and now have
it on blue and red, but how long should I keep it like this before switching to red only?

Viparspectra runs either growth or growth and bloom together never just bloom.

Really? why is that?

Red creates growth, but UV blue creates resin production.

If internodal length is good, go veg/bloom at 2-3 weeks, otherwise you are wasting veg time. I generally prefer 24/0 lights in veg, it keeps temp and RH steady.

When I do my indoor photos I will run my vipras (2 -450) veg them min. of 5wks under blue veg. light only. Then use both veg./bloom switch throughout bloom 12/12 and it generally takes 7days or so to see pre flower. Like others are saying...all depends on strain height, tent height, light distance from top of canopy of plants. Put both switches on.

What distance have you been keeping your lights at for flowering? I'm running a vipar (450) sitting at 14 inches right now. Seems fine no signs of burn or dryness.
