LOL--no, I am not getting frustrated--I am just trying to get you to switch your priorities to where they need to be right now. And that something is to get a space set up. That needs to be done last month...so you are really behind schedule. While it is possible to keep a plant that is very small and young in about any place under fluoros, once they get about 3 weeks they need their own home. However, I wouldn't go larger than 5 gal pots--you don't need a larger container unless you are growing trees and you are not going to be.
You need a thermometer. Forget about the moisture meter if money is tight--you have a lot more things you are going to need to buy that are far more important. You can stick your finger in the soil and determine if you need water.
I would keep all the plants for now. You have not sexed them and you could have some males--in fact, I hope you get some males...it would make me more comfortable with those bagseeds.
Ditch the bagseed entirely after this grow. The Safari Mix is an excellent suggestion. Mandala is my favorite breeder. I have gotten some real great phenos from the Safari Mix. I had one I kept going for years before I lost it.
You do need to learn to crawl before you can walk. And that starts with getting a good space set up for your plants. A centrifuge type fan is going to have to be on your shopping list. I think you may find it difficult to keep a cardboard box the 100% dark that is required for flowering, but it should be find for finishing vegging. Or since you are a mechanic, I make the assumption that you are familiar with tools...including construction type tools like saws and drills? You may be able to scrounge up enough scrap wood to make a proper looking box. I have a customer that is in the shipping business and shipping crates, even quite large ones are available for the taking. Construction sites often have a lot of usable stuff in their burn piles. There are tons of places to get scrap lumber. Flat white paint is inexpensive and is my wall covering of choice. Be creative and resourceful and you should be able to build yourself a nice little space. I have a ton of closet space at my home, so I turned 1/4 of one of my closets into a veg space that is 2 x 4 x 4 with a few 2 x 4 scrap pieces and some 1/2" plywood off an old shipping crate. I turned 2 3 x 3 closets into a 3 x 6'+ flowering space accessible only from my master bathroom. Think creatively and you should be able to come up with a lot of solutions.
You do not really want to grow sativa dominant in a small environment unless you know how it grows. Some of them get quite large and willowy without a lot of special training. I would stick with hybrids for now and be sure to read the descriptions. Check out the Safari Mix from Mandala. These are experimental crosses, but since all their strains are quite good, you should get something to your liking--maybe even something that is outstanding. Once you get a female, we will teach you to clone.
So, like I said, not frustrated, just waiting for you to get your space set up.
