I can understand why you're confused but a metal halide HID is of no value in the production of mj. It could be used for mass cloning because it has the same spectrum as a cool white t5.

You are definitely the first person to express that opinion. I guess that is why we have a forum; so everyone can voice their opinions. I've been growing for 12 years now and I think MH lighting has significant value in both veg and flower. All of the information and testing I have seen and done points to this conclusion.

Metal Halide lights are what most people veg with...we don't use them for fun...you are saying that mercury vapor floodlights are better for growing MJ...well that is where you and the world of horticulture must got your seperate ways...floodlights are not for growing plants...

Yea, that's definitely the first time I've heard someone argue that point of view. I use MH as supplemental lighting in my flower room. Hang 400w bulbs vertically.

A 400w/mv will work with a 400w/mh ballast. It is better for your moms than a mh. It is not a floodlight. Yes a mh will work...in a pinch but it's not the best choice.

You couldn't be further from the truth. Look at the spectrul analysis on a mercury vapor bulb. You are wrong. This is why no one uses them. Fluoros (especially saltwater reef ones) would be the BEST for vegetative grow, followed by correct spectrum LED's and CMH bulbs, then MH bulbs, and finally HPS. I'm not sure where you get your info from but if you want to state that can you please provide some proof showing that EVERY grower in the world is wrong except you. This is why MH lighting and Fluoros are the preferred supplemental light choice in flower rooms to create the broad spectrum desired by flowering plants.

You are wasting your money buying a standard metal halide lightbulb.

If you can't offer up any proof, scientific study, or at least have an intelligent debate about the subject then I am inclined to believe you don't know what you are talking about and I will refer to my 12 years of growing and significant research, reading, and testing in my own room as my proof that you are wrong.

You will in the end prove yourself wrong. I once thought like you but you'll find that a mercury vapour frosted metal halide which is in fact a murcury vapor will promote shoot length far better than a plain metal halide. Don't waste your money on a standard mh lightbulb.

You still aren't saying anything. Do you have any evidence or are you just regurjitating something you heard from the kid at the hydro store who's growing 2 shitty plants in the back of his closet that's lined with tinfoil.

Seams odd. Every commercial op that i visit the only mh's I see are sitting on shelves.

That's funny, cause of 50 or so I have been in; the 9 or so that I have built; and the 3 that I own all or a part of; ALL of them use MH for veg and as supplemental vertical lighting in flower. I'm not trying to argue with you anymore dude. You are not going to change my mind. I know you are wrong and I have been around long enough, seen enough evidence, and read enough on the subject to know that you have no clue what you are talking about. Best of luck to you in your future grows. I hope you get all the yield you pray for. I am just not talking about this anymore with you because you don't have any experience in this area nor do you have any evidence or scientific data to back it up. Plus, everyone else in this thread and on this forum has disagreed with you so either you are the single smartest grower who has such forward thinking knowledge that we all are years behind you or you just don't have a clue what you are talking about. My money is on the latter.
