CFL's??

just my tuppence, but if you are used to using HPS you will find the yield from the equivalent wattage of CFL to be deeply disapponting, distressing even lol

the light penetration is measly, they simply don't pack out the power to produce decent quantities of bud - the quality is fine, it is the yield that is the issue

I recommend you use blue as well as red during flower - it will give less airy buds, for those who care ahout such things

I think every one who's posted in this thread knows that :wave:

Wow, I didn't know CFL comes in such high wattages. if you pack enough of these 125s in a cab, can you get a decent grow room going?

It would do wonders for my heat problem... :chin:

Hi HC - my post was largely in response to Getafix'x remark

personally, I would not say you can get a decent grow room going with CFLs, regardless of the wattage

IMHO CFLs are good for veg, that is all

likewise, plenty of people read these threads but do not post, and I would think it could save a lot of people plenty of time if there is a general understanding of how useless CFls are for flowering

I would add that CFLs still produce significant heat levels and need cooling/venting - and if they are not vented they will break quickly

in fact, they often break quickly anyway

I have seen a thread over on UK420 where Joolz - a guy who actually sells them - was discouraging people from bothering ...

ngakpa, your assertions are rather general, so only generally correct.
high wattage cfl's can compete with low wattage hps for efficiency.
 
Howzit y'all

Let Blunt pipe in here with his pound of flesh.

HOTC may remember this. I did a HPS vs CFL grow a few years back to see how different the results were... I had 2 Grapefruit, one was grown and flowered under a 70W HPS, the other under something like 140W warm white CFL. The end result was that both plants netted about the same amount, maybe 10g a piece dry.

As an experiment it showed that at these wattages results were very simliar. But once you head up to the 250W/400W/600W HPS then results sway in favour of the HPS, mainly down to the level of penetration that HPS has. Also I think if you did a straight shoot ---Watt for Watt then HPS will come out on top for sure.

The only real positives I can gleam from CFL is heat and ability to use in them in real micro grows...

sure -

honest question though - how many people do you know who have persisted in using them for any significant length of time? That should give a clear indicator of their limitations

I only ask because the new imported Chinese models here were quite popular for a while, and genuinely percieved to be a good budget alternative for percy grows ... only for people to discover that they have a very high likelihood of going 'pop' within about 6 months - especially over warmer spells ... with these models the plastic casings also seem to degrade quickly with the UV

given that an HPS will last perhaps 4 - 10 times as long and yield many times more per watt, and that CFLs also still need venting etc. I struggle to see what the draw is

the brand here are called "envirolites" - but if they break so often, there is not much environmentally friendly about them, certainly nothing budget (I have bought 4 and had 2 break)

re. the link HTC has posted above, it all looks very nice, but I think the deciding factor there is surely going to be how much that weighs in at - not much I would guess

as I say this is just my tuppence, but my intention is just to save people time - I've spent about half a year fucking about with flouros, and unless you're one of those people who rolls "glorified cigarettes" not actual joints, I fail to see the point... novelty value perhaps?

yeh Blunt there are plenty of tables comparing HPS and other forms of light - HPS is generally off the graph compared to CFLs, and most other lights

as I say, apologies for being difficult, but I think of CFLs as a kind of "Robinson Crusoe" option... except that if I was RC I would be going for the outdoor

It would be tricky throwing a 150 watt HPS in there :D
 
Yah I too spent a lot of time doing the CFL thing, was not sure where to look when it came to finding an HPS, whereas CFL's were readily available...

I'm cooking with a 400W HPS now, but still have my little 70Whps/100W+ cfl cab, comes in useful for seedlings

I am starting to get upset. All the "helpful" people who are promising me strong CFL's never deliver. Anybody know of any local places which you can buy them online??

hi guys,

the guy Tim-Tim grew with lots of HPS and MH lamps, and then hung some CFLs just as an added bonus between the buds, or so i think.

i'm but a novice to the indoor growing thing.... :redface:

I cant get the strong ones... want over 40w at least. I am in North Africa. To get stuff here is like trying to decode the Rosetta Stone!!

LOL :D

Well maybe if you phone Plumstead Electrical in Cape Town, they can post/courier/ship some 45watt CFLs up to you. Unless you rather get an HPS?

Any reason you would like CFLs?

Peace :wave:

ngakpa you make several good points but to answer your question simply, the draw (for me at least) is that CFLs are extremely 'plug n play' and they can be utilized in tiny spaces where an HPS would require a fan that's almost half the size of the cab. I have about 150 watts of mixed spec in a tiny dresser and vent it with two pc fans and only in the hottest weather do i have problems. i've grown with a 150 HPS and there's no way i could put it in there with such measly ventilation.

after several years of using fluoros i am convinced actually that they are a viable option particularly where space is limited. no doubt all other things equal HPS puts out more lumens per watt though, the fluoro penetration problem (i'm making my CFL studs blush a little here) is real and has to be considered.

Thanks for the info muddy waters, sounds like a very simple setup you have but very effective.
