Finally got some Lowryder seeds - advice on these lights needed please!

My growspace is 2ft wide, 2ft deep and about 4ft high. The lights Ive got at the moment are:
2x 40w 'standard' bulbs (the kind in your living room)
1x CFL, 20w
1x CFL, 11w :o
1x 25w flouro, 3ft long (info is here http://www.fishfurfeather.com/hagen-...acturers_id=13, got light spectrums it gives out aswell)
I will also be using a VERY strong 12" deskfan, this will be on the shelf below pointing upwards, and trust me the air will be able to circulate! Im just wondering if the 20w CFL and the two 40w bulbs, with the 25w flouro as a sidelight will be enough light? Or should I just wait a while and buy one of these

And if I do buy the 600w CFL, how much more yield should I be expecting?
Thanks in advance,
Tom

the 40w standard bulbs wont do anything at all
buy the 600w ,keep your two cfl's , and your flouro
with enough space you should be able to have a good profssional grow

Hello every one you can say that im a newbie grower but i have pretty much the same set up as this gentleman does witha 120W plant light on them about 2 feet away should i upgrade to CFL or wait for 175w MH

Well if youre from the UK, Id go and buy the 600w CFL that Ive put up in the link above, its been reduced from £25 to £20 so its a decent price.
Plus, I think 600w should be enough to grow 2 plants, but Im not sure. 120w should be enough if they arent the standard lights like the ones in your living room, but you wont get a very good yield (aim for 400w or more for a decent yield). Alternatively, buy a 1000w CFL if you can afford it.

I've had good luck with straight 40w fluorescent 48" shop lights. A bank of 4 sets (8 bulbs) produces good bud. Each bulb puts out about 3200 lumens for a total of about 25,000 lumens. I ended up with 6 good sized indica hybrids with large, tasty, sticky buds. The second generation clones produced the same results in about 75 days.

That is not a CFL its an HID. You won't be able to fit that in a normal socket.

It's actually an HPS if you look closely on the bulb.
