If I were to grow Contender bush beans in a controlled environment (greenhouse equipped with heating/cooling capabilities), what would be the ideal air temperature to do so in?
Generally, these beans prefer temps between 60 and 80 degrees F. They do better with minimum soil temp of 65 F. and will have difficulty setting pods in temps above 80 F.
My beans come up good and look healthy for the most part, but 80% of the beans have mostly just seeds inside and no meat. It is just a small container garden. I put new compost every year. Also, it seems the plant dies quicker and does not re-flower. The problem seems to get worse year after year. I thought it was lack of water but last year we had sufficient rain and I still had the problem.
My only explanation is that your bush beans have some sort of virus and it could return year and after is your containers aren't sterilized. Here are a few articles for you to review so you can try to pinpoint what is afflicting your beans. If it in fact a virus, you will want to consider planting disease resistant cultivars.
I have bean bushes thriving. Lots of leaves and covered in blossom but no beans form. Blossoms fall off.
This could be a sign that there is too much nitrogen in the soil, or that it is too acidic. You can offset this by adding phosphorus and potassium into the soil, along with some dolomitic lime to adjust the pH.
This should get your beans producing. Until then, here is an article to help with bean plants: https://www.gardeningknowhow.com/edible/vegetables/beans/bean-blossoms-no-pods.htm
First-time gardener with zero family or friends that garden. Just put my first raised bed in the backyard with 5 bush beans and cucumber to start out. My cucumbers and beans I believe have powdery mildew so I bought Daconil but now my beans look worse. I'm not sure if it's from the daconil or if I'm doing something else wrong. It almost looks like the leaves are burnt :(
What soil did you start out with? This looks like a severe fungal infection gone wrong! Daconyl can help. but too much will cause burning. Sometimes it will be necessary to start fresh. Infections such as this are aggressive, and can be very hard to get rid of. It may be best to get rid of this soil and start fresh.

Our raised bed was made with mulch, soil, and fertilizer. Gosh, I really hope I don't have to buy all new soil. Is there a way to find out if it is in fact the soil?
When to plant bush beans indoors and how deep
Beans grown indoors can be sown at any time. Just make sure that you have enough light, and that your potting soil contains beneficial microbes. Plant them 3 times deeper than the width of the seed.
Growing beans indoors will require about 100 watts of light per plant, with 200 being around optimal.
If you intend to start them indoors, and move outdoors, then I would advise against this. They prefer to be started where they will finish.
For when to start- This can depend on the variety. Follow all packaging instructions on the back of the seed pack for information on when to start the specific cultivar. This article will help you to grow beans:
I have flowers on my bush bean plants, but it's August and I planted the seeds in May, and still no beans. I ordered them from Burpee Seed Co, and never had a problem with any of their seeds, also, there is some spotting on some of my plants, which after reading your article, I'm pretty sure they have Mosaic virus. I live in the most southern part of Nevada, desert environment, but I planted yellow squash, and they are producing abundantly. I need your advice please.
It may not be too late to treat your bean plants with neem oil. Here's an article to help:
My green beans are not straight but curved. What causes this?
Unfortunately, your photo did not come through.
There are a few things that will cause this. The most common issue will be improper and watering habits. That doesn't rule out disease or insect damage, though.
