Hey man life finds a way...But there are a few things that could make your plants a lot happier and might give you great results on a small budget.
Get a couple T5 light fixtures. They are fluorescent fixtures so not much heat or energy use, and you could fit all of your plants under a couple of decent sized T5's. You might spend $60 on lighting.
Use good soil and nutrients. GOOD =/= EXPENSIVE !!! Just find a bag of anything meant for tomatoes, usually with worm castings. Fox Farm and Happy Frog are the two most recommended for cannabis, but just talk to someone at your local nursery and see what kind of soil they have. Add perlite into your soil at a 1:3 ratio of perlite:soil. Fox Farm nutrient trio is probably the best nutrients for your money if you're not trying to power grow. It's a pH buffered line of nutes so that your water doesn't get wildly thrown through the pH ringer when you're trying to adjust concentrations of nutes. They also have a feeding schedule that is pretty helpful. You only really need the top three on that chart, all the other additives are for if you are dialing in your own personal feeding schedule and tweaking small things. (I am not affiliated with FF I just used their nutes when I first started out and it worked great). The only other thing about nutes is maybe keep some CalMag+ on hand. Depending on your soil you may or may not need it but its like $10 a bottle and can save a lot of headaches down the road.
Buy a pH meter. Seriously. Don't try to even absentmindedly grow without one. They are $14 on amazon. If your pH is not around 6.5 for soil, your plants wont be able to uptake all the nutrients they need and you will starve them to death and we will have to mourn for the fallen ladies. Don't make /trees sad. Buy a pH meter.
If it was bagseed that you planted you're going to want to keep them on a 18 hours on/6 hours off light cycle for about a month, then switch to a 12/12 cycle for another two months to let them flower. The light tells the plants when to flower so you are in complete control of them.
Treat the ladies well and kill the boys. Chances are at least one of those plants will be male. Kill it. Kill it with fire. Kill it with so much rage that it doesn't have a chance to pollinate your ladies and bring down your quality and yield. Seriously though, male plants are bad news unless you're trying to make a personal seedbank. Plants should start to show their sex after a month or so. Boys look like this and girls look like this with little white pistils.
Smell wont really be an issue until a couple weeks into flowering. If you don't want to build some kind of air filtration system then I would suggest getting some Ona Gel and spray. I use it still just to get some of the smell out and it works great. Amazon is your god haha.
Also this chart of plant problems will be good to help you identify what is going on with your ladies if you run into some stumbling blocks. It's almost inevitable that you will probably make a mistake your first time. I killed a plant my first time, it happens.
As for chopping and drying, you should wait until the trichomes on your buds are milky amber. If they are clear, wait to harvest another week or so. Dry them for about a week in a dark room or closet with a fan running on low to keep air circulating. I use a big plastic tote with string across the top to hang my buds to dry. After the stems are easily snap-able you can snip the buds off and put them in quart mason jars to cure. Open the lids every day for about 10 mins for the first week and make sure you don't have any residual moisture that will cause mold.
After that, enjoy your homegrown...and tell everybody that asks that you got it from some random guy!
Enjoy your new hobby man and good luck with your ladies, it can be super rewarding and therapeutic. Peace!
