That's my flower room, I run both side by side and rotate the plants daily, so they get equal time under each light.

We will see how the current grow goes. My first two were Mexican bag seed and took 13 weeks to flower but Jesus Christ was it worth it.
I do want to move up in light. My space is small, 6 sq. feet with 5 feet of height. Could I go higher than 250
I did the same thing with my first grow. 250 watts CFL mexibrick bagseed, 12 weeks. It was good smoke but, I wanted to move on to HID lighting for better bud density. CFL's don't have the penetration to produce anything but airy buds. I soon realized that CFL's were a gateway drug.
I just bought a 400w HPS lamp, ballast, and sealed air cooled reflector last week for $209 shipped! My grow space is 2.5' x 3.5' x 5.5' and the air cooled 400w HPS runs cooler than the 350 watts of CFL's that it replaced.
Here's the best part... I used my light meter to compare the two lighting systems. I get the same amount of light (2000 lumens) at 35 inches from the HPS that I get from just 1 inch away from a CFL. That's AWESOME! I'm so happy. I'll never go back.

Would this be a suitable 250 watt light in anyones experience?
hell the 400 watt is $10 more...

I can't speak for the quality of that model as I'm not familiar with reputable brand names. However, in my research for this project I read a lot about the benefits of cool tubes and/or air cooled reflectors in managing the heat of HID lighting in small spaces. It may be something to consider.
Works for me.

Yeah, that is a nice jump in watts for only 10 bucks. I'd go with the 400.

Your using 105 watts of lighting now. Go up 45watts and get a 150 hps and double the light. I guess I'm just a cfl hater. (other then seedlings and clones and to be honest I don't like them for seedlings). I see so many people spending two months growing a weeks worth of smoke.
People keep making the mistake of comparing like wattage bulbs but they should be checking the light output. I hear the "cfl lights are cooler" crap and it's just that, crap. Remember 250 watts of cfl light runs cooler then 250 watts of hid light but it only takes 75 watts of hid light to get the light output of the 250 watts worth of cfl's. 
Keep spreading the truth!! Every other cultivation forum on the internet is filled with the falsities of CFL usage to which you allude. I couldn't count how many times I've read someone claiming they could let they're plants rest against CFL bulbs (They will always burn plants if the bulb's wattage is above 27watts). Or, as Magash mentioned, the ridiculous claims that CFLs put out very little heat- this is utter nonsense, 300watts (for example) of CFLs puts out a lot of heat and requires very good ventilation.
Another falsity is that they only produce fluffy buds; my experience is that you can indeed grow dense buds under CFL's---- You just can't get much past the one ounce per 100watts of CFL ratio.
I've personally grown a few plants under a temporary, custom-built 330watt CFL board and was able to achieve slightly better than the one ounce per 100watt mark (so I was getting a bit more than 3 ounces from a single clone), BUUUTTTTT the cost of the rest of the setup (fertilizers, ventilation, etc.) was about 10x the cost of the CFL board my friend built.  This would have been a nonsensical use of money, but I was purchasing all the ferts, etc. under the assumption of moving in an HPS shortly thereafter.
So myself, even as someone who was able to grow ounces of dense, frosty buds under just CFLs, my opinion is it's a waste of resources---- CFLs kinda suck. Again, CFls are not "cooler running" than HPS; and CFLs put out less light per watt than HPS bulbs.

Psuper, do you think that adding a 90W LED setup in the Red-Blue spectrum to ~450W of CFLs in a 2.5 x 2.5 foot area would be able to get somewhere between .5 and 1oz per 100W? I'm just wondering bc I currently dont have the money for an HID but i have this CFL and LED setup from long ago and was trying to shoot for a couple of oz. out of a 2.5 x 2.5 area.
I know it all depends on genetics and care and what not...but what would i need to get yields that high?

Well, yes, but hopefully closer to 1oz per 100W instead of 0.5oz. Less than that and you're either doing something wrong or you have to start over with different genetics.
**again, my experience is limited to and recommendation with this, if you're actually going to use CFLs, is to grow a single plant/clone.** (I've since upgraded to an HPS.)
With or without the LED light what you want to do is get lighting on the top and one or two of the sides of the plant. I had used 55-65watt bulbs; get them very close but never touching the plant. Your grow space sounds alright for this amount of wattage, but add some side-lighting.
You need very good air exchange for the amount of CFLs you're using. The heat they produce will be right next to your plant. Heat stress affects growth and reduces amount of visible trichomes on stressed buds. Add silica if you're getting any heat-stress.

Provided you got everything else down- fertilizers, not over-watering, control of temperature and relative humidity in the grow room, enough air for the roots, length of vegetative cycle, et cetera, here's two things that helped me:
1. To make the grow more "forgiving" I added silica to help with heat stress (got the advice from Magash, originally) and used a whole 5gallon bucket of Fox Farm Ocean Forest soil to let the plant have a big, deep root system and allow for time inbetween waterings----- The 5gallon size bucket was not necessary for a single clone at a time that weren't vegged for very long, but, since there was only one plant and thus no competition for space for additional pots, why not let the plant grow a big root-system.
2. Second is just what I mentioned originally about adding one or two "walls" of CFLs, or an LED in your case, in addition to the bulbs on top. And a ton of air-movement for 450watts in a 2.5' x 2.5' space.

My last 2 grows were 250 watts of CFL and my current is 275 CFL. My last grow was four plants that gave me almost 4 ounces and I picked 2 a week early and the other 2 a couple of weeks early. I hated growing from mexican brick seed, it took forever to flower. I do plan on moving up in light on my next grow. We will see how this grow turns out. Hopefully I can get the same results or better.
