Which lights should i pick?

- Growing one plant
- Soil grow, gallon pot
- Either 12/12 from seed, or 18/6
- How many plants can i fit under 2 x 55w PL-L?
- My pl-l fixture i will buy, can i change the bulbs? is their any particular 55w PL-l bulb i should be buying

Anyone care to answer or have an input :D

PL-L for certain. The design of the cfl is nowhere near as efficient - the insides of the coils block each other. I have a 2 x 55w kit from AHSupply in a freezer for my mom & nursery cabinet, and have had up to 8 small plants in there. I have also re-vegged a couple of pretty large gals under them. You should be able to change the lamps in any fixture that you buy. HTG Supply has both 2 and 4 lamp fixtures that look good for the money, or AH Supply has very nice kits for DIY. The high-pod used 4100K lamps all the way through with very good results, but I use 4100K for veg and 2700K for flowering. Fluorescents are different than most light sources - they all have a broad spectrum with some minor adjustments for visual peaks in whatever the advertised spectrum is, so they aren't as task-specific as HID's.

These re-veg ladies were moved out of the freezer and into the tent for the picture. Sorry for the quality - reducing the resolution didn't agree with it.

just compare the two different designs and you'll see that a 125w cfl won't distribute light as even as 2x55W PL-L. The flouro tubes shade themselves ;) of course you can change the bulbs, another big advantage over cfls where you'll throw away the electronic parts as well.
Just have a look around ion this section and don't let the information get feeded to you. A good starting point is the PL-L club ;)

It looks like a nice fixture. I have used both cheap Chinese lamps (PlusRite) from 1000bulbs.com and Osram lamps, and can't really state that there was much difference since I didn't do it side-by-side. I would lean toward Osrams if they are readily available - actually, you should have much better access to them in the UK than we do in the states. As for yields, there are waaaay too many variables to predict that, but if you look through the following thread you can probably find a style similar to what you have in mind and see their results.

I doubt that you will have any problems getting 10 grams. My first grow with them yielded about .4 gpw, and that was with horrible problems from root aphids and a soil mix that ran out of steam about the 4th week of flowering. Good luck!
 
big cfls are a waste of money, poor design n cost to replace, id def get the pl-l, there what 70 bucks, id say over both of them that id recomend u just get 3 42 watt cfls but the cost of that once all is said n done will be more then your pl-l which is better technology for your dollar. if u happen to have enough extra cfls laying around to equal 100 plus watt then just run them, if not get the pl-l.

That was done under 6 x 55 watt lamps, PlusRite brand, 4100K in veg, 3000K in flower, and the strain was Purple Crack. Depending on your setup, you may want to veg under a lamp with less blue than the 4100K - these were extremely compact, no stretch to speak of, and very tight internodal spacing.

nice, was it 12/12 ? how long veg?
and final yield?

The 2x55w pll will be more efficient and better light distribution than the 125w cfl.

cool bro, what should i do do you think
under 110w's, 12/12 from grow?
or an autoflower
and how many plants?

I've never done either auto's or 12/12 from seed, so you're on your own there. If you knew that you had a real healthy plant, one could probably produce as much as two with the limited amount of light that you will have. You could start with two and cull one, but I can never get myself to get rid of one after they are established.

I would do one or two, top them early (perhaps a couple of times) and lst the shit out of them. The screen in the following link would be very helpful - using a scrog works very well with the limited penetration of the lamps (although they penetrate far better than you would expect). Keep the light about 4" above the tops of the plants, and if things get too warm, use a small fan to blow between the fixture and the canopy.
