I'm a first time container tomato grower. I planted the last week of april(bonnie's better bush), but only got one tomato from my 7 plants before the summer heat set in. I am using three 65W grow bulbs from 8am until 2pm, as my balcony faces west, and the sun takes over from 3pm until 7:30-8:00 pm. I learned early that my tomatoes needed the artificial light. I didn't realize, however, that heat makes tomato plants become sort of "dormant", and slows growth and development to a crawl. This happened to me. After some research, I realized that I was adding too much heat to my already warm grow area. I decided to try setting up a small fan that could blow a breeze across the plants and, theoretically, cool them down. I can tell you that this has absolutely worked. It has been over 100 degrees here lately, and my plants have come back to life, and are setting fruit and growing like crazy again, in spite of the heat. I leave the fan on while the sun is up as well now, as it helps them stay cooler under any light. I was wondering if anyone else has any more tips on heat, and it's effects on fruit set and yield?
