CFL vs HPS penetration

the name of the thread is "CFL vs HPS penetration"...
and haven't we already established that HPS penetrates further, stronger?

why are you still trying to justify CFLs as credible sources of light? They are great for lil grows, we know that already... why is there still sand in your taco?
your incessant additions of charts and graphs and animations isn't helping the HID community embrace the cfl community any further becasue you are pushing that shitty propoganda crap down our throats.

The results speak for themselves. CFLS will grow you some pot... bigger CFLs will grow you more pot than the little cfls. But when compared to the equivelently powered HPS lamps, there is no comparison - CFLS are not on par because HPS grows the most. PERIOD. How? Pentration of the canopy creating more, fuller, denser bud sites.

no one has beef with cfl growing. its the napolean complex that comes with the cfls die hards thats the problem. no one is trying to send you to waterloo why do you keep trying to go?

No sand in my taco.

It's not propaganda.

No, bigger CFLs do no not grow bigger plants. The intensity is spread upon the surface area. You are only demonstrating your complete lack of understanding.

It depends on your wattage of bulbs. In certain cases, 400w HPS and below compared to CFL can possibly match or even exceed the PAR umol/m^2/time.

PAR is the ultimate plant-usefulness measure of light.

HPS sucks. Seriously. 7.6 CF(conversion factor)... means 140k lumens results in about 18,421 umol/m^2/time(seconds) of PAR applicable wavelengths.

remember this? 1 x400 watt room of HPS and 1 400W room of full spectrum CFL's same plants same feed everything identical exept the lights. wht won the HPS now 400w is 400w right? now if the par was all it was cracked out to be than it shoul/would blow the HPS away watt for watt, but it did not why? INTENCITY from the 400 HPS is more efective at growing plants under an HPS lamp than the superior PAR rating and less intencity of the CFL's FACT! its there infront of your eyes proof!

looks to me that the cfl hood is closer than the hps hood and still under performed.....

I don't need to understand something that is irrelevant. It doesn't work.

I don't believe in theory I believe in results whats so hard to understand?

CFL THEORY SUCKS.
HPS PRACTICE RULES.

thats the way things are for now...

maybe in 5-10 years the technology will change (LEDS) but until then know your role and grow in your cab:hump:

too bad these kids cant grow like the grown ups and use big boy lights...instead they have to play with flashlights in there mom and dads closets...

The problem is no one ever mentions that CFL's dont penitrate more then 3-4 inches when nubees start to read about lighting. THATS why you cant just plug in a few 42w CFLs in street lights and such. CFLs will grow just as good as HPS as long as you can keep your plant encased in them like an iron maiden.

which costs a bunch of extra cash in adapters,cords,and whatever you use to mount and hang all these little lights that have to be moved on a daily basis(because if your plant isnt growing on a daily basis you are doing something wrong). too much trouble for little buds....ill stick with the power to produce.....:joint:

little buds maybe if you don't keep any eye on how far your lights are from the plants.

Not a big deal if you check your EC and PH daily

Whilst we are on the top of cfl vs hps..
Im currently veggin under a 65w cfl, it has been 4 weeks now.

Space isn't really an issue in the grow room and i was wondering if you could give some guidance.

I have a 600w hps i will be using for flowering but i am curious as to whether i am better of using it now for vegging as a lot of people seem to do.

It seems to be growing quite well.

The CFL is the right spectrum however the hps admittedly has a lot more lumens. I don't really want to buy a conversion bulb. Is it worth veggin on the hps do you think as will the growth be that much more noticeable?

I didnt really want to make a new thread so please don't think im hijacking.
any help?

you spent money on a ph/ec monitor and you grow under CFL's? or are you using HPS? if your using CFL's I would have bought a better light before i payed out on the monitor IMHO

p.s

sorry i can see you use HPS i got the post mixed up,

It would be really best to have both lights going for full spectrum. I think you have a pretty close toss-up and you will probaly get lots of different opinions on it but now your four weeks into veg....going to HPS its probably best since your plants are getting taller.
