are envirolites 125w any good

[kulan hunter]

i have a choice of lighting but can only fit one light fitting in my grow tent.
my plants are in the 3rd week of veg stage,
my tent is only (70cmx50cmx80cm) pics below plus a couple of my babys.
which would you use. 125w envirolite blue or mh 150w?

 

[the widowman]

150w MH or 250w would be better. and get a HPS bulb for flowering.

 

[swansong]

the cfl will work just as well, and will help prevent excessive heat.

 

[SunnyD]

actually, I saved wattage and had less heat using my 250 hps. I had cfls before and my room was hot as hell.....

 

[Mr Green Man]

Indeed,

The Way I understand it heat has more to do with light efficency, Big MH/HPS bulbs are hot but that is beacuse they are also 400/600/1000 Watts and put out loads of light.

In regards to that 125W CFL I just got one, i'm using it for sprouting seeds and I will keep my mouther in under it later. It is a good light, I really like it, but for actual growing I would go with a HID.

Try and get a switchable balest, that way you can use the same Ballest for MH and HPS, I have a 400w one and it works great.

This addvace may not work for you, but I hope it helps.

PS if you go with CFLs spend the extra and get the 200Watters

I agree, if you want to choose between a 125w cfl and 150w mh, then i would definately opt for the cfl. If you intend to flower under the same bulb, then its worth considering either a 250 w cfl or a 250 w HPS.

its not the same.....a 250w cfl only puts out 8700 lumens...my 250 hps puts out 33000.......

 

[swansong]

Without starting another thread, its not all about lumens. I agree that the HPS will put out a lot more lumens, but the HPS is only 35% efficient.

It uses nearly 20% of the wattage to create heat.

Also i think 8700 lumens sounds a bit stingy for 250w of cfl

I have a 125 w envirolite CFL that puts out nearly 12,000 lumens and more importantly is 100% par.

haha......its all about lumens. What you care about is light...more specifically, light energy. That's what plants use during photosynthesis/growth. Light is measured in lumens.

HPS is more efficient. A typical 250 watt HPS bulb/unit will produce about 27,000 lumens.

23w CFL = 1600 lumens = 69.6 lumens/watt
30w CFL = 2000 lumens = 66.7 lumens/watt
40w CFL = 2600 lumens = 66.3 lumens/watt

compared to

150w HPS = 14000 lumens = 93.3 lumens/watt
250w HPS = 28000 lumens = 112 lumens/watt
400w HPS = 50000 lumens = 125 lumens/watt
600w HPS = 90000 lumens = 150 lumens/watt

lol... i did say without starting another thread...

Lumens is a measure of the human eyes perception of brightness.

Plants dont see the same spectrum, so lumens is only half the story.

A great place to learn more about what is important to growers.

Envirolites indoor hydroponic envirolite grow lights, grow cabinets and reflectors.

And what CFL figures are those. ?

I Have a 58 w T5 that puts out 5,800 lumens and thats a standard fluroescent, producing 100 lumens per watt in the correct spectrum.

 

[SunnyD]

I'm bout to check that out.....lol, lets just make another thread and get this solved.

 

[UserFriendly]

Swan is correct. Lumens are a measure of light as it relates to the human eye.....not a measure for plants. search photosynthetically available radiation or PAR watts.

As for watts...well a watt is a watt (radiant energy). 125 cfl watts = 125 MH watts, you dig? same heat.

MH > hps, Hps is for weight, MH is for quality. you growing to smoke or sell?

Of course now you can get Cermaic Metal Halide bulbs. Phlips MasterColor Ceramic Metal Halide ~ CMH ~ HPS-Retro White peep the specs....AMAZING! I suggest the 250w. CMH, the only bulb you'll ever need, seed to harvest. If the cmh doesn't give you that funny feeling, i suggest the most powerful MH you can get.

 

[SunnyD]

That really doesnt make sense....ok i now know how light is measured in plants...but i've had a cfl grow....shit loads of cfls...and it was no where near the growth of my hps.....i have it maybe 7-10in from tops and with my cfl's they were 1-2...

 

[swansong]

Interesting. Has anyone heard of the plasma bulb yet? I have a friend who owns a small commercial lighting company, and he tells me that within a few years everyone will be growing with plasma bulbs that are only an inch or two.

 

[swansong]

were you using proper CFL grow lights or the low wattage ones you buy in home depot ?

 

[SunnyD]

i had proper ones.....i had 2700k warm white.... u know anything about the UV-B bulbs?

technology = the shit.

If you understood how light is measured "in plants", then it really would make sense.

 

[swansong]

well i think your referring to the black ultra violet bulbs, they are useless for growing. The spectrum is totally wrong for cloryphyll synthesis, flowering etc not to mention they are usually far too low wattage. 6 - 58 w max.

Also the warm white 2700k CFL are perfect for flowering, but they will slow down the cloryphyll synthesis during veg.

Halides = uber v-b

He's talking reptile bulbs.
