Although you can use both for both cycles, the results are better in changing bulbs, apparently (I wouldn't know I haven't done it)
You got that reversed, HPS is for flowering.
yourbud Reviewed by yourbud on . HOMEMADE LIGHTING/ & MORE 1) I found the HPS bulb I'll be using, its a 400 watt, I will make the reflector myself, that part is easy. So I guess I will need a socket, ballast and cable? How do I hook this stuff up, or what type of stuff should i use? Electrical stuff... 2) ALSO, a girlfriend of mine keeps telling me not to start anything right now because of the season, I tell her over and over its indoor, its regulated it can be done anytime! Isnt that correct? Why would she think this? I think shes insane, I hope Rating: 5
