does or has anyone veg with a hps ?
Ok I will join.i was just starting a discussion
Good point, using an MH (or T5 fixture) pays for itself that way.I used to use hps the whole way through but I would find at the end of harvest number 2 my bulbs output was greatly diminished.
Perhaps that is merely something from the past when HPS (streetlight) bulbs spectrum was of less quality than nowadays. It differs per HPS bulb too, I use the 400w philips son t 'agro' for vegging for example:People go on and on about internode length with hps but I never used to have any issues as long as light height and temps were in check.
HPS Does work for veg, most types of light will. The reason they use MH it is in a different spectrum of light, it is in the blue spectrum. You will notice late summer/fall the sun puts out more of a red spectrum of light. Which is why HPS is most commonly used for flowering. It is to simulate what nature does. sun puts off more blue spectrum spring early summer, red spec in the fall.You will veg a more vibrant plant with nodes closer togather than you would using the same wattage of MH verses the same watt hps at the same distance. Use HPS is just fine for veg, but its more in the red spectrum. They do sell converter bulbs, you can get a MH bulb to go into your HPS ballast. Make sure to check which brand ballast you are using and google the appropriate mh conversion bulb. Why spend the money on the watts and not use the very best bulb?i know that the conscience of most ppl say to use a MH but why not use a HPS? it seems to work or so ppl lay claim
its what i am currently using
dude we need you in on this thread https://www.rollitup.org/t/4-plant-600w-grow-pics-included.836993/#post-10682430Good point, using an MH (or T5 fixture) pays for itself that way.

"Agro lamps are suitable for flowering as a standard HPS lamp, but are better for growth. These lamps have 30% more blue light in the spectrum and are developed by Philips especially for horticulture."
