HPS & MH have been a thing if the past for me since the late 80's. It doesn't matter how you get the lumens up to par or the color temp (cool, or blue spectrum for growth, warm, or red spectrum for flowering) where you need it for the stage if growth you happen to be in. If you can do this without all the heat & huge electric bills, all the better. (I still have my HPS in storage). I've been a florist since the early 70's, & back in the day, house plants were a big fad & flourscent grow lights were big. For over 10 yrs I'd argued that this works for pot too. I was called crazy & the guys would say oh well, she's a girl, how would she know. Tired of arguing, I just kept it to myself after that. When I found this forum, I was flabbergasted to find so many growers doing what I've done for over 30 yrs. Why try to grow plants indoors as large as your outdoor grow? Outdoors, grow vertically if you want, indoors, grow horizontally out of necessity. Go sea of green or similar (SOG). I have my own methods of doing things that many may disagree with, & Ill be posting them in 'my camper closet grow' if your interested. Changing up a few things, but not technique.
catbuds Reviewed by catbuds on . Which is Better, 400w MH or 600w HPS During Veg. Stage I have a 600 digital ballast that can run 25%, 50%, 75% or 100% power. Question, which provides better growth during veg. stage, a 400w MH bulb, or 600w HPS bulb? My hydro store guy doesn't sell a 600w MH, he said most people use a 600w HPS during veg and flower stages. Thanks for your advice. Peace, PIF:thumbsup: Rating: 5
