Just about every new grower has or had a set-up similar to yours. Six months from now, you'll have so much growing stuff you'll wonder what the hell happened. It's call "the growing bug" and it's hard to stop once you've started.
A few suggestions to prevent you from making the same mistakes I and one million others have done when first starting growing.
1. You will want to water your plant just about every time you look at them. Don't. Not only do roots need water....they need air too. Saturate your soil, and give 'em a few days and repeat.
2. You will get informational over-load on here. Keep it simple. Between you and the plant, the plant's the smarter one about growing. It's your job not to kill it.
3. Don't give your plant nutrients for about a month, and only give 1/4 to 1/2 the recommended dosage, and then wait a few weeks before giving more.
4. Regardless of what you'll read here and elsewhere, keep all the leaves on the plant. They are the solar panels and lungs of the plant. You can learn more from watching how a plant grows on it's own the first grow, and down the road you can adjust your growing technique as you see fit.
5. Did I mention keep it simple yet?
6. Don't over analyze your grow. Sit back and enjoy what it's doing. You will want to transplant your seedlings into something bigger in about a month. If room allows, I suggest a 5 gallon container with holes at the bottom.
7. If and when you go to a hydro-store (you really don't have to), don't buy into the hype and sales pitch they'll give you. Most of what's out there is snake oil.
8. Craiglist should be your place to look first for growing equipment.
9. And finally.....keep it simple.
