I'd skip the molasses for right now. You can play with it when you got the basics down. I love how your recycling your containers. I do agree with Corbat though in that you made a few mistakes (but that's ok, that's how we learn), you need improve your lighting, and fertilizers. I'll go a step further and suggest how I would do it on a tight budget...
Containers - I start off my seeds in a #6 nursery pot, which holds 1 quart of medium. They'll run you about $5-$6 each. If you want stick with recycling, you can use 2 liter soda bottles. If you save the top part after cutting it, you can even use it for your cuttings (clones). Here's a good site on making a soda bottle terrarium:
http://www.stormthecastle.com/terrarium/soda-bottle-terrarium.htm , the only change I would do is to add holes to the bottom since in our case we're more interested in using the bottles as containers.
Growing mediums - There are basically two types, soil and soilless. Soil is made up of sand, silt, and clay. Soilless mediums includes peat moss, bark, wood chips, coir, stylophone, perlite, etc. Basically anything not sand, silt, or clay. Miracle Grow uses peat moss, because very abundant, it's organic, it holds water and nutrients well, while also having lots of air spaces, giving roots plenty of oxygen. For years this was the best stuff to get and to this day many gardeners add peat moss to their soil if it contains to much sand to aid in water retention. Now people are slowly switching to Coir because of environmental reasons, but it's water holding abilities is not as good as peat moss, and it's a little more expensive, but it's less acidic, and very renewable.
Roots organic and fox farm use a mix of peat moss and coir and a bunch of different types of manures. Miracle Grow doesn't say what kind of manure they use, but I'd guess it's poultry since it runs a little hot and poultry is cheap and widely available in the US. There is nothing wrong with MG using peat moss and poultry (it's really good stuff!), it's just nice to know what's in your medium so you can better understand what your working with. When you shop for soils, ignore the brands and pay attention to the ingredients. If it has coir or exotic fertilizers like bat guano it's going to be more pricey. Is it worth paying more for coir and fancy poop? It all depends and what your looking to get out of it. I personally don't think so, but it's a hot issue and many intelligent people will disagree with me.
Fertilizers - First you have organic and chemical then you have Vegetative and Flower fertilizers. Organic has been used since the Earth was created. Chemicals are stronger, more concentrated and pure, but can cause environmental problems and they are more likely to burn your plants.
Since your just getting started and your already using an organic medium, I would suggest you start out using Worm Castings (1-0-0) for vegetative growth. As soon as you see yellowing leaves you can foiler spray using liquid worm casting. Its very safe and very good for your plants. I've added it to my seed starting mixes and both my cuttings and seedlings love it. Just feed no more then once a week if using liquid or use less then 10% when mixing it into your soil if using dry powder.
Another option for vegetative growth I'd highly recommend is fish emulations (5-1-1). Notice that higher first number, that's the nitrogen and because it's higher it's more likely to burn so you need to be a little more careful, but it's really good stuff. Another benefit of fish emulsions is that it's cheaper and more readily available. Most Home Depots and Lowes carry a brand called Alaska's Fish Emulsions for $6 a bottle. Worm castings is a little harder to find, but will usually run you $13-$16 for a bag. $5 if you can find a bottle, but it won't last as long as the Fish Emulsions.
I'm less picky about flowering fertilizers, since by then it should already be pretty healthy and I'm just looking to add Phosphorous and Potassium (potash) which is just mineral rock and ash. Kelloggs makes pretty good stuff and it's available at Lowes and Home Depot.
Water - one of the benefits of using tap and rain water is that they contain lots of trace minerals. Even chlorinated tap water is fine... just take a look at the grass and shrubs in your front lawn. I often hear that to much chlorine can kill the microbes, but you'll be supplying fertilizer anyway so you'll be able to make up for any lost nutrients along the way.
PH - your growing organic, so don't worry to much about this.
Boosters - Don't use them. Not yet anyway. Wait until you've done 2-3 harvests and gone through a few battles with pests and nutrient deficiencies. Once you know your strain you can slowly tweak your nutrients and start adding new things.
Lights - you want around 100 watts per cubic foot. For a closet grow I'd try to aim for at least 300-400 watts if you want to flower indoors. If you only need to veg for a month you can get away with 120-150 watts.
Insecticides - If you want to stay strictly organic look into diatomaceous earth, neem oil, and organic insecticidal soaps. If your not super picky about going organic, water and 2-3 drops of dawn dish soap inside a water bottle works really well. You can even add garlic, pepper, and cinnamon to the mix to make it extra deadly.
Vinegar ... normally used along side baking soda to adjust PH. Again your going organic so you don't need it. It's also commonly used in the garden as a weed killer so I wouldn't go around spraying your plants with it. I love it for sterilizing my grow room though (after I've removed my plants). Spray your grow area with vinegar, then come back with hydrogen peroxide (never mix the two together) and you've got a damn good disinfectant.
its what i started off with untill i had enough of a harvest to upgrade. and i still use 5 gallon buckets.....
But then I don't use
