Hey guys... ive been having trouble finding CFL's with the 6500k spectrum. ive been using two 2700k CFL's not knowing it was red spectrum so i went out today and baught some, the person there said they should be 6500k(cool spectrum) but they didnt seem too sure, it has no information at ALL on the package and i tried looking on the website for this product but its not on there. Two 42 Watt CFL bulbs, 2700 lumens per light. GE energy smart bulbs.
Walmart.com - Always Low Prices! - GE Energy Smart CFL Light Bulb: 42 Watt (150W Equiv) 2-Pk

can anyone help me figure out weather these bulbs are the right ones or not cause i dont wanna spend anymore money on the wrong shit. thx

You can't tell with out reading the package.
but Costco carries a lamp 65 watts giving 500watts of light fro about 9 bucks
and it works great

It doesn't say what they are, but the line "Same quality of light as Soft White bulbs" leads me to believe that they are soft white as well which would be the 2700K spectrum, you are looking for cool white or daylight, they will appear blue-ish as opposed to peachy

Stoned4good - What's up bro. You still having a hard time finding 65K cfl's? Unless you're prepared to order online (there's quite a few places with a great selection - overpriced, but higher wattages available), you're kind of stuck with Walmart/Home Depot/Lowe's, etc... Walmart's 42 watters are 2700K "warm white" for flowering. They have 2-packs of 26w bulbs at most of the stores that say "Daylight/6500K" right on the package. Perfect for vegging. Don't know WHY they don't carry the at least the 42w 65K's, but... Just pick up one of their 10" clamp lights, and get a socket "Y" splitter from Home Depot, or your local hardware store, and use both 26w bulbs in the same light. They'll fit in the cheaper 8 1/2" clamp light if you buy a socket extension also, and bend the reflector a tiny bit. Hope this helps man! Peace, good growin'!

The closest thing to 6500k i could find was 4100k natural light bulbs. Ive been to honestly every store in my area searching for the 6500k's!!!!!!! im freaking out cuz i think the 4100k's are completely useless, check out this diagram below in the 4100k range.

Ive never even heard of that place before lol, and can anyone tell me if the 4100k are indeed useless?

i know they are different spectrum's, but ive been using the 2700k 150watt x 4 equiv for vegging and its been working alright, im just wondering if i used the 4100k x 4 100watt equiv if it would work better for vegging. And i wan tto know how accurate this diagram is.

Look at the chart.2700k is for flowering and the 6500k for vegging
Both will work but ya wanna go with the cooler light for veg (keeps them from streching if you can slam your light right up next to them.) Ya want small distances between internodes,,allow's for LARGE colas..tighter the plant less sq footage being used (ie put another in there:))

but if you look at the chart under "4100k" it pretty much says their completely useless. so would that mean I'd be better off vegging with the 2700k's since on the chart it says they create my chlorophyll activity. and "4100k" is the closest i can get to 6500k in my area concerning lights.

the low kelvins, 2500 to 3200 , are the red spectrums, and are for flowering or budding. The bulbs are cream colored and sold as soft white.

The high kelvins , 4500 to 6500, are for GROWING or VEGGING, and are the blue spectrums.

I bought mine at STEALTHHYDRO.com,the 85Watt DUAL SPECTRUM II ones. They will sell 105 bulbs next week and offer 20,000 lumen full spectrum lights by the end of June.

yeah, i know theres always options over the internet, however i don't have a big space to deal with. and a tight budget. i do realize im using the wrong spectrum of light however they are growing pretty nicely(not to their full potential but still) i just think the ones im using now would be more effective than the 4100k's since on the diagram 4100k's dont do anything for the plant.
