To answer your lighting question, yes you can use either or both spectrums for vegging.

It is not the color temperature that makes cannabis flower.
It is the length of the day that determines this. (Unless it is an auto flower strain.)

Many people like to use both spectrums because it is closer to natural sunlight.
Others use only an hps during the whole grow cycle.

More lumens is almost always a good thing. So get those lights in there! :thumbsup:
tikiroom Reviewed by tikiroom on . Started a new plant, how long do I veg for? So after my very first plant grow it turned out to be a male... :( and was an experimental plant so not knowing what to do I may have ended the veg cycle earlier and went to flower and then went back to vegging thinking it was too early. I had veg lights on him for about a month and again was 24/0. I've started on another plant. I was wondering how long should I veg for? As of right now my veg cycle is 24/0 for about 1 and a half weeks into growing. I'm just asking so my plant doesn't veg Rating: 5
