If you used the 2x 315 from the start(18+ hours a day), you have used it as your veg light already!I was planning on using LED if I ever got around to needing a veg light.
I like not having to swap bulbs (MH to HPS, weg to bud). The CMH bulb is a full-spectrum light, so great for any part of the plant's life cycle (we only have to adjust time and intensity).
That has to be better overall for our plants than simply blue than red spectrum(more orange really)
I have some work to do, the girls have been drinking water for 6 or so days now...
The light coming on, guess who forgot to attach the yoyos at 5 weeks of flowering, luckily only 1 started to fall so badly I had to intervene at the cost of getting very sticky (trichs I won't be getting back),
A bit more light,
Nearly there,
That is pretty close to full power, I can't wait any longer!
