So, I know that the general consensus is that you should use an MH bulb for vegetative growth but I started doing some research about using an HPS bulb for vegetative growth out of curiosity and came across some interesting things. The following was taken from Ed Rosenthal's "Marijuana Grower's Handbook":
MH lamps are the type of lamp used outdoors to illuminate sports events because they emit a white light. They were originally promoted as the light to use during the vegetative stage of plant growth, before the plants are forced to flower. But now it is generally recognized that plants grow as well vegetatively under HPS lamps as under MH, so they are not used that much because they emit less total light than HPS lamps and produce lower yields.
I found that to be very interesting. I also came across the following article for those who interested. http://www.hightimes.com/read/grow-hack-does-switching-metal-halides-hps-flowering-work. I don't know if hightimes has a bad reputation for poor article validity but there is any validity to it then I think there's enough information here for me to start being interested in this. I think Ed Rosenthal's word has more than enough merit I'm in the middle of my first grow ever and I've always been one willing to try new things. I have a couple of extra HPS bulbs laying around waiting for when it's time to flower. I'm thinking of giving this a shot. What do you guys think?
