I grow blueberry shrubs here in Madison, Wisconsin, but all of our shrubs are planted in the ground, so my methods of pH control are not necessarily best for your situation. How are you measuring pH? If the leaves are deep green color, the shrubs are healthy, and pH must be reasonably close to optimum. We have hard water, supplied by the City of Madison. Our water has pH = 7.6, and it gets an addition of 5% white vinegar before being used on our blueberry shrubs. If you are using soft water, or rainwater, the amount of acid needed will be less, so you need to know what kind of water you have before proceeding. Also, you would have to know what kind of growing medium is in the pot. Some people grow potted blueberries in spaghnum peat moss, and this material tends to be acidic with no chemical addition needed.

I Love all the windows! It doesn't look like you have a lot of room for upper cabinets, so will you also have dish storage under the island, in dish drawers or something? I'm imagining making sandwiches, snacks, breakfast. The dishes are probably near the dishwasher, but most of what you need (meat,cheese,milk, lettuce) is way on the other side of the island. Then when your clear the table, you are walking around the probably-open dishwasher to get to the disposal in the sink. So the DW should probably go on the other side of the sink, with dish drawers in the island across from the range. You're on a farm, right? You might want a utility sink in the laundry or mud room. ( I miss my old double concrete sink!)

If the concrete floor is damp from moisture seepage, then the humidity level in the basement should be fine. It actually may be too high and may need a dehumidifier in the summer. Part of my basement is finished. I had a carpet and pad installed a few years ago. I specifically told the installer I did not want a pad with a moisture barrier. My thinking was that if the concrete were to become damp due to high rainfall then I did not want the moisture to be trapped below the padding. Ideally the moisture passes through the carpet and padding and the portable dehumidifier I have in the basement would dry out the air as needed. I was worried trapping any moisture would create a potential mold problem. So far it has worked well for me.

Here is my first cut at your space. Rev. 1 (and btw, super-duper measurements!! kudos!). I put an approximately 11' length of sofa along the wall and since you have that short wall before the windows, I put a large ottoman type piece. I put a swivel chair in "corner" of the living space near the windows so you can swivel to converse or watch TV? maybe, or swivel toward windows for views. I put a 60" long (max. to maintain walking space to other part of the apartment) and keep it 16" deep because it will stick out 17-18 with baseboard, cords, etc. Set TV on that console. I put a 52 x 30 coffee table that would be 18" from the front edge of seating area. You could also put a small round decorative stool/table, beside the swivel chair for a place for someone to set a drink/cup of coffee, etc. Now to the dining area. To get a nominal seating for six in this area, you need a 30" wide table and you might have to have it made. A live edge custom table with metal base might be great in your space if that is a style you might like. Then in the living area, go modern and sleek. I would do the coffee table, even smaller if you wish with glass top and metal base to work with the dining elements you select. The chairs at the dining table have to be really narrow across the front seat edge. That is the big challenge. This table is 60" long and 30" wide. For every day, 4 chairs could be placed there, two on each side with the additional two chairs in the corners just to give a more open feel and help maintain views. You will need some additional lighting and a arc lamp would work well on the fireplace end of the sofa and you might want another floor lamp beside the window end of the TV console. Unless you shorten the sofa on the long wall, you have no space for end tables and lamps. So something to think about when shopping. I put a 36x16" bench in front of the fireplace for one person. The seating area will only seat 5 so total would be 6. You could bring in a chair from the dining set if needed and just squeeze folks in. Watch the size of cushions for any sectional you buy, each person needs at least 24" of space, and generally don't like sitting next to each other. Also, TIP, make sure your sectional pieces join together "under" the pieces so you don't have brackets on sides. This allows for greater flexibility in "next" house and even if you just want a seasonal change of some kind here. I'll play a bit more with this later today and see what other options I can come up with for you.
