ok so i went and bought some cfls?

i got a 150w hps goin right now and jus put her to flower and wanted to get a couple cfls to light up the sides of her. will these work for flowering? i couldnt find on any of the packages where its said 2700k or 6500k so i got these jus wana know if there ok for her thanks

You guys are killingme with these CFL numbers, I think I'm going to quit giving advice on CFL's

Looks to me what you have is (2) 19 watt CFL. They are equivilant to a 75 watt bulb so you added the 2 together and think you have 150 watts worth of CFL's.

In reality you have 38 watts of CFL.

No wonder people list they have 1000's of watts of CFL lighting and getting poor results or think that 400 watts of CFL is a lot cooler than HPS.

The math is just confusing everybody and what they got.

Soft white should be OK to flower, is that all you are going to use ? Do you have other lighting ? Didn't they have bigger soft white bulbs ? I usually go no less than 23 watts and haverecently taken a liking to the 40 watt cfl's for VEG only.

if you read my op it says i HAVE a 150w hps and i wanted to get a couple cfls to put on the side of her because i jus put her into flowering and shes mad bushy. Those 2 cfls that i JUST got are jus a little extra lighting jus wanted to know if they will do any good.

im jus adding them in with the 150w hps i already have

I think its cool how different wavelengths of energy influence life. Those look like they will be in a warmer spectrum. I think that each one does something different , but they all would benefit the plant.I found this info on a different board.I didn't write it It doesn't have the #s your looking for , But they are here.

Selecting Fluorescent Lamps for W Output


What is a Kelvin scale?
One way light is measured is on a Kelvin scale. A Kelvin scale expresses the exact color the bulb emits. Bulbs in the range of 2700 to 6500 on a Kelvin scale is ideal for growing marijuana. Plants respond not only to the quantity of light, but also the quality.

What color spectrums are available in fluorescent bulbs?
Fluorescent bulbs have the most range of spectrums than any other bulb. The spectrum comes in various spectrums, determined by the type of phosphor with which the bulb is coated. The following fluorescent types are as listed, along with what they may accomplish for you.
· Full spectrum fluorescent bulbs have all the colors of the Kelvin scale. This bulb is good for vegetation stage. Note: This spectrum fluorescent is used in hospitals nationwide in helping people with "depression".
· Wide spectrum fluorescent bulbs will restrict development of side branching, helps plants mature faster. This fluorescent is high in the red, orange and yellow color range. In fact, this fluorescent is the highest than all other fluorescent bulbs. As a matter of fact, this fluorescent is much like an HPS color range, which makes it the best all around choice for flowering stage.
· Daylight spectrum fluorescent bulbs are very high (if not the highest) in the blue range on the Kelvin scale. This fluorescent promotes an arctic blue look. I suggest this fluorescent during vegetation stage.
· Cool spectrum fluorescent bulbs will promote multiple side growth, nice green foliage. This fluorescent is high in the blue range, giving off a bright white appearance. I suggest this fluorescent for vegetation stage.
· Warm spectrum fluorescent, will promote extra thick stems and branches, and will give you about 5% denser buds than other spectrums. This fluorescent is high in the red range on the Kelvin scale.
·[FONT=&quot] In the old school of fluorescent growing, an even mix of warm white and cool white tubes has been proven to be the best combination of light spectrums to use for flowering stage. If wide spectrum bulbs are unavailable in your area, then this is the combo to use.

OK, what's an OP ? I tried to find something because I did read you wanted to add them to the side but didn't find it. My Fault.

So you have 1 plant, with a 150 hps and a couple CFL's one the side ?

That should be a good setup. chief.

Instead of the CFL's you might have tried standing two 4 foot t8 fixtures vertically or even 4 of them, that would be the sweet hookup.

What do you think about doing that ?

OP original post, yea no worries man i didnt explain myself well enough yea i got one Bluberry clone with a 150w hps and shes mad bushy so i wanted to put some light on the sides to get to the sites that arnt getting as much light, i looked into the t8 4 footers but decided to jus use these for now but for my next one i will be using those in combo with the 150w hps.

good looking out man

yea i guess the question i should be asking is is there any "harmful" light for a plant or is light light?

In real watt per watt, hps is more efficient, and cooler than florescence and cfl's. Now get that.
