Ok as a suggestion... you said gas is expensive, so I'm guessing ur in cali... Do-it center sells the BIG fertilizer bag of Fox Farms Ocean Forest soil/fertilizer mix for $12.95. This shit is the bee's knees.
For CFL's, it gets expensive(for us cheap people) And you will need 6 bulbs all together. 3 6500k or "daylight bulbs" (100w equiv), and 3 "soft white" 2700k bulbs. 6500k for Vegetation, 2700k for Flowering.. If your a cheap bastard, just buy the 6500k and after 3 or 4 weeks(your veg period) just go return the bulbs and use your new found money to buy the other bulbs.
Here is a check list you may want to follow:
3 6500k CFLs
3 2700k CFLs
Light timer, or set alarms on your iPhone
Soil reputable for MMJ.
This is all you really NEED to grow your plants.
Weed grows extremely easily in GOOD conditions, but it dies extremely easily in poor conditions. As other have said, the more you put in, the more you get out of it. I would suggest reading all the "sticky" threads in the CFL forum section along with the General Marijuana Growing section. They are very beneficial to you and your grow. When I first joined this site, i was better off than you are, but still to this day I come on here and learn new things each day. Gather your supplies, and be prepared for your journey. I also suggest reading through peoples SUCCESSFUL grow's and learning what they did. There are many tactics when it comes to growing and its good to prepare yourself. I am NOT the smartest person on this site, far from it, but if u have any questions, feel free to PM me. As your a newbie, I can probably answer most questions for you about which CFL's you need and different jimmy rigging plans u might have. Cheers bro, good luck
