i will bro, i will. its just that right now i have a lot going... and i have never done the experiment myself. if there is someone out there who has done the experiment with good results, i would really appreciate the info, and everyone who posted some information on here i thank you. pretty much im wondering if i should switch out my 400watt hps with my mh bulb maybe like every other week, or just leave it in there indefinitely.Why not just do it and you will see for yourself!.... and then you will have the answer and will be able to help others when they ask about it.
you have the root-bound thread right? and you are seeing that end so just keep experimenting and you will have the answer to your question!
if you dont have any first hand experience with it, please dont reply... i too can think of all the things it possably could do. im wondering if anyone has tried it out. if ya haven't thats cool man no worries i haven't either, if you have please share your experience with us.
for everyone in this thread talking about something that has nothing to do with light spectrum... GET THE FUCK OUT OF THE THREAD.
criticism should always try to be constructive, not merely negative

What the fuck are these trollers going on about?
You know who I am?
Good. Come to Portland. I'm going to make you swallow your words and your teeth.
I'm not "acting like everything is cool" because I don't give a shit what drama you little bitches feel like you need to start. I'm posting in response, I did try it out, and I wanted to keep this thread on topic.
Too hard for these guys. God. They are soo cool. Such a helpful benefit. How could I ever... Post actual results from real experience... I mean, shouldn't I be ranting about off topic shit, bringing drama across threads, and dropping insults left and right.
That's how you cool dudes got your clique right?

what having e war or the swaping of MH and HPS weekly
my guess would be it wouldnt improve growth but thats really just a guess but cant argue with both at the same time the more light the better
sorry about any thread jacking
Been growing many,many years. My first HID grow was 1991,and it was strictly 400 Metal halide. Veg was short and tight with 1/2 inch internodal growth. Flower was light and soft. Good harvest, but the buds were loose. Grew that way,for a year.
Then,I got a 400HPS. Vegged tall with a 2-3inch inter-growth. Buds grew like poodles, but got hard and heavy.
So, I tried the MH for veg and HPS for flower. Best results up until that time.
Finally, and still currently, I veg with the MH then ADD the HPS,and I get the best results. I haven't tried both spectrums in veg,because it is over kill. With 1/2inch between nodes, why mess with it, and add expense to the power bill?
My buddy likes to use strictly halide the last 2 weeks. Says it increases THC content, but I see no practical evidence of that.
I have a 1 meter square tent 78 inches high. 240CFMblower,and a cool tube 400mh/hps digital. I brew beer in the same walk-in toprovide CO2 and get 12-14 zees/4months.
I hope this helps,and ignore the dumb shit from the peanut gallery. Better to focus on the little darlings.

In response to the ORIGINAL POST, I would advise looking into Phillips HPS retro white (Commonly Called CMH or Ceramic Metal Halide)
It is a full spectrum bulb, and it the one stop shop for both veg, and flowering. My last grow was in soil, in a 2x4, using 2 400W CMH's and I must say i was VERY impressed. some other locals who have been doing it much longer than me said themselves that my stuff was better all around compared to theirs (They used a single 1000w in a 8x8 and only got 2x the yield as my 2x4)
I know a lot of factors make up the end product, but I am absolutely 100% sold on CMH bulbs!!!! IMHO the only reason not to use them, is running 600W HPS's for the energy savings.
SCREW LUMENS, LOOK AT THE COLOR SPECTRUM !!!!

dude thank you so much for that idea, ive always had a feeling that both spectrums of light would work best on the whole grow. im going to save up and get one, do you know where i can get a good 1000watt bulb at for future reference? thanks so much bro

Sadly, the CMH comes in a maximum of 400W. IF your really concerned about spectrum, I would adjust your garden to support a couple of 400W's and SKIP OUT on the 1kW HPS. I promise you your plants will LOVE the swap, and your room temps should drop noticeably.
Do a internet search on CMH, and you will find the graph that shows the difference in the spectrums. I could be 100% wrong, but I believe that when dealing with HID lights, lumens only measure what we as people see, not what the plant can "use"

i already have a 400watt system, i can get the bulb for that, buy another 400watt system and get the special bulb for that. have the 1000watt in the middle and the 400's on the sides... i think that would be really fun to try out. i know i can get another system for around 120-150bucks, how much are those special bulbs bro?

I just ordered 2 "Philips MASTER COLOR CMH 400W HPS RETRO CDM400S51/HOR/4K/ALTO" at $121 Shipped. (So about $60 per)
Keep in mind that YOU MUST USE A MAGNETIC BALLAST for these bulbs, electronic ballasts are NOT COMPATIBLE with the CMH lamp. Also be sure to get the correct one that you need, there are 2 types. Vertical or Horizontal. I bought the horizontal ones, but I "think" the vertical ones are a tad bit cheaper. Either way pay attention to the bulbs run position.
Hope you enjoy

I think that's 100% right. In fact the human eye sees best in the color range that plants don't use. The PAR curve has a hole in it right where the photopic (eye) response sits. For growing, lumens are actually a measure of uselessness! For a given wattage, the higher the lumens rating, the less effective the bulb is for growing.
The light bulb industry is mostly focussed on lighting - HPS lamps being used to light up parking lots etc so they tout the lumens rating and often dont give the PAR.
