Full Moon and cauliflower?

It is not surprising that some people don’t take moon planting seriously when TV commercials make statements like “the increased light of the Full Moon has hastened maturation of cauliflowers”.
All vegetables are exposed to light from Full Moons. Maturity times for different varieties of cauliflower vary from 11- 26 weeks, so the slower growing ones would be exposed to more Full Moons than the faster-growing varieties. In fact, radishes, which are sown after the Full Moon, can mature in a month, and would be exposed to the least amount of Full Moon light.
I thought the statement may have been based on the Moon being in Perigee (closest part of its orbit to Earth) and the reflected light from the Full Moon being slightly stronger. However, the only time the Full Moon was near perigee this year was back in January. Cauliflowers require cold weather to form the curd, and the coldest weather normally occurs when the days are shortest and the plants are exposed to less sunlight. It is more likely that the cooler temperatures this year have assisted the early maturation of cauliflowers, and that TV ad doesn’t make a whole lot of sense to me.
