While I wouldn't reccommend CFL's after my personal experience, they WILL work, they just aren't going to give you those heavy, dense buds that an HID light will. After they've successfully germinated, and you've got your 2nd set of true leaves, it is time to start hitting them with the light. For the first 2-3 weeks, or until you see pistils develop (they look like little white hairs), you will want to use a 6500K bulb. I would shoot for approx 100 ACTUAL WATTS per plant, BARE minimum. Forget what the bulb claims is the "incandescant equivalent" because that number isn't important. All you care about is the color, and the actual watts. As far as color, you will see a "kelvin" rating on the packaging. They range anywhere from 2700k-6500K, the difference being, the higher the number the whiter the light will look. The lower the color, the more red/orange the light will look. A 6500k bulb is most comparable to a Metal Halide bulb if you're familiar with HID lighting, and the 2700K is closer to the High Pressure Sodium lights. Anyways, enough rambling - to keep it simple - get several small, or a couple of large 6500k bulbs to start out with... make sure the actual watts adds up to at least 100. I wouldn't reccommend transplanting your autoflowering plants, because you don't want to stunt their growth in any way, especially since they've got such a short veg period. If you have the space use a 3 gallon pot from the jump. This will also take one more variable out of the grow that you could fuck up (transplanting). Next - go with a high quality soil. You will likely have to visit a specialty shop, like a hydroponic store or find it online. Some quick suggestions off the top of my head - Fox Farm Happy Frog (im using this now - good stuff), F.F. Ocean Forest, anything from Humboldt Nutrients, etc. DO NOT USE MIRACLE GROW, even if your buddy tells you it works, it's not the BEST for your baby, and can actually cause lots of problems down the road. Your next issue will be fertilizer - again - I'm going to stick with Fox Farm, because that's what I'm currently using and it's doing great. Plus they have a great feeding chart that comes with the nutrients that will keep you from guessing and burning up the plants. I use Fox Farm - Big Bloom, Grow Big, Tiger Bloom, Open Sesame, Beastie Bloomz, and ChaChing. I know that sounds like a lot, but it really isn't, especially when you go to looking at some of the stuff from Humboldt or Advanced Nutrients. And don't get overwhelmed - you don't have to get everything at once - you could start out with just the Big Bloom & Grow Big then get the other bottles as your babies progress. It is also a good idea to get a bottle of Cal/Mag - this is great to add just to make sure all the nutrients you feed the plant are able to be absorbed & keeps you from having lockout & defficiency problems down the road. Back to your closet/room - make SURE you have good ventiliation. You don't have to worry about concealing smell in the beginning, but you do have to keep the temperatures down, and keep the air circulating. Get a hygrometer (temperature/humidity gauge) from WalMart for like $10. If possible, keep your temps between 65-75 do NOT let it get more than say 82-85 degrees because the plant will slow/stop growing. Humidity during veg should be between 55-62%, and under 55% once you start flowering.
You can get all the advice you want to read on sites like this, but it's up to you to grow your plants. You CAN give them nothing but water and get buds at the end, or you can give them 16 different bottles of fertilizer each time and still end up with buds. It's a matter of how much time you want to fuck with them, and how much money you want to throw into it. It's a weed. It will grow like crazy in the wild with no human intervention. We try our damnest to replicate mother nature - everyone has their little secrets and every company has the newest and best formulated fertilizer. Just stick to the basics in the beginning - proper watering, proper levels of food, proper lighting, proper heat/humidity and you will be just fine. Don't overthink it too much or you'll go crazy.
