Ok I've read far to much info to be certain about my lighting. I have 4 plants that have not sprouted as of yet. I only have two 40 watt 4 ft flour bulbs. I believe I need more light than this correct? If so what do u reccomend as for wattage and quantity of lights? I'm def wanna stick with flour or cfl as this is my 1st time and funds r limited. Pleeeeaaase help? Thanks to all !!
desperate for clarification!!!! please help

Just get a cheap HSP with a MH conversion bulb. After you're done buying the high wattage CFL's/fittings and/or a high powered Fluoro, a HPS system won't cost much in comparison.
You need at least 3000 Lumen per square foot of room, or about 100watts per plant.

Initially for vegg, depends on how big you are going to let them get.

Not too technical, but more light is always better when it comes to flour/cfl's, so if you get them almost free them use as many as possible.

Yep, that's why I suggested HPS because when it comes to flower time you'll get bigger, denser buds. I always say that when judging when to start flowering take in to account your grow space and that the plant can double/ tripple in size : )

Some people start with a 48hour dark period (dn't really know about that) and then you need complete darkness for 12 hours a day. No light leaks. Even a normal house light can mess with the 12/12 cycle.

I would recommend during the flowering stage you should have 2 23-40W on each plant
you're good for the seeds and about 1~2 week after the seeds but i suggest you get about 2~4 42 watt CFL's per plant and keep them about an 1~3 inches away from your plants. 6500k or daylight/coollight for vegging and 4200k or warmlight for flowering. I started with CFLs to learn as well.

Yes flower only. it does'nt hurt to leave some 6500k in the mix also. I have mine on a bar. 3-42w I get to many going and nedd side light for the 400w.

You can get the 6500 with a mh conversion bulbs that fits into a HPS system.

Don't think any mh hits 6500k. and it works the other way around you can get hps conv. for a mh ballast.

Depends on the strain. Indica has a long vegg period with a relatively short flowering period and satvia vise-versa.
