the big bang mh vs hps during veg!!

ok if you want to compare a HPS lamp to your CFL bulb because they have the same spectrum the compare a 100w HPS lamp that has the same spectrum as your 100w CFL.

A 24w T-5 bulb may produce 4200 lumes but that's over the length of the whole bulb. Do the math and find out out many lumes per inch your 24w T-5 bulb puts out for the length then compare oh let me do it for you...

24w T5 bulb - 4200 lumes say its at 2 feet = 1w per inch at 175 lumes per inch
So the MH is about 2 inches wide from side to side so that would come out to 2 watts and 350 lumes what the T5 bulb would cover but lets say your running 2 of those T5s then that's 4 watts and 700 lumes in the same amount of space of 2 inches square so by that math the 70w MH can produce better growth in the same amount of space even a 35w MH produces more lumes per watt in the same amount of space.

Yes it may produce less lumes over the T5 but like I said the T5 bulb's lumes are spread out through the whole length of the tube and not in 1 spot.
Ok once agian i will reiterate your HPS bulb, doesnt have any advantage over a t-5 cfl bulb, and it cost more to run to produce less lumens, the comment about lumens an inch makes no sense, the size of the bulb doesnt mater you use the bulb in the most effcient way possible vert, horizontal what ever, but if you take shortcuts on the only thing that ensure your produce your just gonna be left wanting

you comparison ok

70watt HPS bulb produces one spectrum and 3000 watts or 6000lumans in your new internet example way to search and is tinny which means tiny plants which fine but it limits you

my t-5 lighitng ficture(95 bucks though) with three bulbs on is 72 watts and 12000 lumens and can light a 2ft plant or cover a 2ft area and get good yields, and be up to 4in away from bulb

you notice that nice white powder coating on you Hps bulb, thats make it a single spectrum, high cost cfl bulb waste your money if you want, on the 20 to 0z in the picture and im being generous

SSW I'm sorry but the numbers that I was telling you were't the exact numbers because the thing that they guy photocopied wasn't exactly the right one so here are the specs of my 70w MH and 70w HPS

Ok I'm sorry but the specs of my 70w MH lamp and 70w HPS lamp was wrong that I said and the mean rating of them I do believe is when they are around 40% of their life rating used but by the rule of thumb when 6 months hit when they say to replace your bulbs they are still in their initial life lume rating. Also my bulbs are glass with no coating thank you very much.

----- 70w MH -----
http://www.goodmart.com/products/sylvania-mp70-u-med-64547.htm
Approx. Lumens (initial): 5200
Approx. Lumens (mean): 3900
Color Temperature/CCT (K): 3000

----- 70w HPS -----
http://www.goodmart.com/products/sylvania-lu70-med-67504.htm
Approx. Lumens (initial): 6300
Approx. Lumens (mean): 5350
Color Temperature/CCT (K): 1900



This is what my HPS looks like and my MH has the same outer bulb no white coating. I was going to take a pic of my 70w MH bulb to but my camera battery is dead so I can charge it and take a pic and upload it just for you.

That's not my lamp. I was saying that MH and HPS lights can get as low as 35w and I pulled that up for you and others to prove they come that low. Also I never order any thing online. It was the guy at the electrical place that didn't print out a full detailed specs of it and I wanted to know what the specs are exactly so I searched the Product name that is printed on the bulb its self.

in my experience, you would grow more with similar amount of t5 over 70w hps (70w t5 vs 70whps)

but only because the t5´s cover more area and allow more plants. in budsize the hps has the t5 easily beat.

though im curious about that thread on t´5 and aquarium speciality lights (t5 lights that only produce spectrum perfectly suited for plants)
normal t5´s have got a shit load of Green.

Exactly but in the small 1square foot area that a MH can cover in veg the plants can out grow faster then what a T5 can do in that 1 square foot area but the T5 can cover more area if its a 2 foot due to it being able to cover more area. But in flowering and veg you can have the tops of the plants about 3 to 4 inches maybe 5 inches from the lamp its self. with out hurting them. I've had the tops of my plants almost right at the level that the bottom of the dome is with out burning my plants and when flowering being able to get a HPS or MH that close to the tops with out having to use a cool tube or air cooled hood is a huge bonus.

I am do but the wattage for the amount of area they take up to use is the question to.

Now here's the even funner part

toolage-87-355602-albums-supplies-hardware-picture1822570-4.jpg
LU70/MED number that is printed on my 70w HPS lamp

Oh what's the product name on that site that I linked you to of a 70w HPS light with the Product code of LU70/MED
http://www.goodmart.com/products/sylvania-lu70-med-67504.htm

The product number of my 70w HPS bulb matches their site and its the exact same brand and the specs are

So there proof now take your little attitude and labeling someone more or less full of crap and using google to get pics witch if you would have looked at my Album or posts that I have done you would have seen that it wasn't googled and taken off someone's journal besides the pics I took and posted my self.


Just a little even more fun here's the lumes per watt my lights put out
MH - 5200 lumes / 70w = 74.28 lumes per watt
HPS - 6300 lumes / 70w = 90 lumes per watt


I did a little rough searching and found 2 different K rated 125w CFLs and here's link and specs of each

----- Feliz Blue 901981 | 125W CFL Grow | 6500K Light Bulb | Mogul 5U -----
http://www.expresslightbulbs.com/index.php?main_page=product_info&cPath=682_8_115_138_601&products_id=1439
Lumes - 5,000 , Watts 125
5000 lumes / 125w = 40 lumes per watt
With only a 10k hour life rating
6500k


----- Feliz Red 901991 | 125W CFL Grow | 2700K Light Bulb | Mogul 5U -----

Nice come back Toolage , this thread has been very interesting I am a newb but have been gathering info for the last 4months and started an indoor hydro grow. Debates like this are real informative cause both parties share their experiences and knowledge good or bad which is a real help to newb's like me. Thanks guy/gals!

p.s look out for my grow journal(once I learn how to upload pics) im using a 600w mh for veg and a 600w hps for veg in a superponics syytem, using gh flora 3pt + additives , got trainwreck , himalayan gold , cheesy dick and vk.







Do not believe a word I say nor the pics I post , they are all someone elses words and pics I am only a fan!

There are alot of threads that are going on. Like another one that I posted in Generator for powering a room, I some research on what a gas powered and a natural gas powered generator cost to buy, cost for fuel every day/month and roughly how long of a life span they have vs the cost of solar vs the cost of wind.

any idea if this bulb will do any good in a pc grow?

http://www.lightingsupply.com/c100s54-m.aspx

Just happens to be what I have, i already mounted the ballast assembly in the old power supply housing and have the socket wired in.
Im gonna start a temp test in a few min. just to see what its gonna max out at. i will try to enclose the light above glass, hopefully isolating temps a little bit.

Ideally I want to use a 125 or 250 cfl, but this is what i have right now, and worst case i enclosed my hps ballast in a fan coled container. :)

Hey. That lamp looks good to me. You might be better off using that instead of buying a 125w CFL. As for the 250 if that 100w HPS lamp that you have right now has better specs stick with your HPS if you can find a HPS lower wattage then the 250w CFL then go with that.

i use 2 x 250w in my 39 inch square tent and they work fine for me
i thnk a lot has to do with the bulb - use a cmh (i like bettern mh) by philips better penetration then t5-and hps by eyehortilux
i use them all the time 500w of multy spectrum

mh or cmh best out for veg -great growth less stretch

mh,cmh-best for first 1/3 of flower reduces stretch
hps- the best at second 1/3 of flower producing rock hard buds
mh,cmh best for final 1/3 bud fatten up

i use flouresent tube first two weeks when on water
then third week food and cfls till flower if tent in use if not in use i use my cmh
for flower i use both my cmh and hps i spin pots 1/4 turn every day and rottepositioning under lights once a week
i add uvb for 1 1/2 hour a dy mid day after about week 3 or 4

luck to all

good luck with your grow pal

The reason people use hps over mh is it puts out more lumens some of the top breeders out there only use hps I'm doing a grow now using only hps and my plants grew huge short nodes and the plants just plain love it plus my plants get 125 watts per sq ft hope this helps
