Compact Fluorescent Light Discussion

[BobBong]

well over a month, roughly 34 .. or 35 days old tied right down, the main stem is well over a foot now.. but the plant only stands 10" tall... the secondary growth is picking up alot, soon it'll be 12/12 time... but this apt.inspection i have needs to happen before it things get...sticky...

I am gradually replacing the crappy foil with reflective sheets, addressing the light loss issue brought up earlier

Great thick foliage dude. Raise the light a little for flower to get some stretch. The stretch will give you bigger buds in the end.

That's how you grow foliage people!

Just think how big it would be if you used CO², like twice that size.

Well done.

[Zandor]

just a note: CO² will not work with fluorescents lights. There is not enough lumens for the plant to process the extra CO² you must use HID lights if you use CO².

[BobBong]

4 150w bulbs at 2900 lumen is 11,600

how much more do you get from a 600w HID or HPS

A shit loadmore...

I think a 600W HPS is like 113,000 with a reflector...

I think....

Somewhere I got a chart that shows the increases.

I didnt think C02 was limited to lumens...I thought color spectrum was as important....

Older floros didn't have the full spectrum like they do now...

Seems if you have enuff CFL and lumens, and light spectrum the Co2 should be functional...

Where am I off here???

Lead me to stoner paradise and I will follow..

It's about the plant having enough light to process the extra CO² efficiently. CO² will not increase the THC content but it will increase the foliage and bud producing area and that will give you higher yield.

fluorescents may work a little but not for the cost. HID is the only way to properly use CO² either Mh or HPS will provide enough light. We can get out the slide rule and do math ( Intensity is I=L/D²) but all comes to the same thing in the end no matter what you call it lumens, par watts what ever term you want to use it's still the same thing. More light is better.

Really CO² needs HID lights the more the better. One thing about reflectors is not only do they reflect light....they also reflect heat that goes with the extra light too. I stopped using bat wings or any reflectors years ago. Kool tubes are the way to go with Mylar lined walls and roof.

Do the light setups with the glass shield fuck up the light?

I had read somewhere that glass eats the light pretty good.

i saw on your grow zandor what i thought was handing MH bulbs...thats the way I have mine...just hanging...

thanks and lemme know..

[Zandor]

I use glass tubes on all my lights now, that was an old grow it's going back different now. I'm even throwing in a twist. No Mh lights at all this time veg room gets only 1000 w Hortilux HPS bulbs then mix standard and Hortilux bulbs in Kool Tubs with plumbing. No hoods, no bat wings no refelective heat either. Just Mylar on the walls and roof, white plastic floor the light bounces everywhere. Blinds you when you walk out at night....lol...you can't see a thing it takes your eyes about a full minuet to re-focus in the night before you can walk with out killing your self....longer if you have a buzz.

HARDDON glass is fine and Kool tubes are the best way to go you can get the light with in inches of the plant so penetration is very deep.

[HARDDON]

I just got a new dual MH/HPS system with glass plate bottom, tube cooled heat fan and blower...

I thought you said in another post though, that once the light is with 12", penetration stops or is maxed out and any closer lighting wont do anything...

Did I read it wrong?

Thanks
