CFL confused.

LunchBox05 · Apr 11, 2009

Ok, Im going to be doing a PC grow case soon and Im doing my research before hand, smart no? Anyways Im looking to Home Depot to grab my CFL's but there all these "energy saving CFLs" which Im down for savin energy but it says it's only using 9-13W but producing about 60W, so which number should I be going by? And which lights should I pick up? I was hoping to get away with 2 26W soft white, and 1 26W daylight. Would that work for a singular plant in a PC grow case?

Srry to bump the question guys, just a little confused.

Go by how much it actually uses (26w are usually 100w equivalent). Use daylight for veg, and soft white for flower. 3 26w might be enough for you. I have a rubbermaid setup and use 6 or 7

Thanks grow, Ok, so now Im going to Wal-Mart to grab my lights, fukin conglomerates, gotta love em! But Im figuring this should work for my lighting. http://www.walmart.ca/wps-portal/popups/shoppinglist.jsp?tmp=1239593598239&lang=null I figure I'll use 2 of the 26 W and the 40W in the middle?

Your link didn't work, bro. It just showed me my empty shopping cart. :mrgreen:

Don't use "daylight" (~4000k) bulbs for veg, they are the wrong color spectrum. Use "cool white", which are 6500K, then "soft white" (2700k) for flower.

That's uhm... half right?

Daylight is 6500k(or above 5000k). Cool white is 4000-5000k, or in around there. Warm white is 2700k to 3000k or so. Soft white can be right above warm white, or below, but can be often be found @ 2700k aswell, making soft white identical to warm white, sometimes!

You do want daylight for veg, avoid cool white bulbs completely.

Right now I'm starting my two test seedlings with two of each; (23w)day and (20w)soft. I've put the day bulbs closest (right on top of) them with the softs off to the side on a stripped down vanity bar. The little ones are eating it up with no complaints. At this point I'm just happy they're alive because I germinated them too long and they almost dried out. Mmmm think I'm going to go stare at them for a bit more. Go figure the farmer's son gets a kick out of watching things grow!

Oops your right. I get em mixed up myself sometimes. I usually don't even look at the titles of "cool white", "soft white", etc I always look on the packaging for the color temperature (measured in kelvin). Thats the info thats most important to me.

Yeah I was halfway to the register with cool whites before I thought to look at the color temp on the back of the package.

My "daylights" are 6500K. Just read the box. I guess it depends on the manufacturer.

pot dePot's n:vision daylights are 5500k. The soft whites are 2700k
