>>169888Some bees are extremely small. bumble bees and honey bees are only 2 of thousands of bee and wasp pollinators. Outdoor plants will almost always be pollinated by some form of insect. If you live in a very large city or equally nature-desolate place, you may need to hand pollinate.
Also, better pollination isn't about 100% fruit set. It is about fruit size.
>>169891All greenhouses have yo have fans. the one I worked in used smaller fans at the ceiling, massive 5 feet diameter exhaust fans, and long ventilation tubes that blasted air over all the plants. When ever the heating or cooling system kicked on (every 10 minutes) it was like a wind storm in there. However, you still needed to pollinate by hand when we didn't have bumble bee hives.
You have to understand that plants sway in the wind and are not jarred by the wind. It is the jarring motion that knocks the pollen loose for pollination. That's why sudden sharp motions from physically shaking the plant or vibrating the flower cluster are what pollinate better.
You are debating a former professional tomato grower, fyi. Now I just grow them for personal use.
