I think it is the balance of food and water to support the amount
of light. The more light the plant has, the more food it needs
and the larger it can grow. We had some "mature" plants when we
moved from Chicago to CO. The difference in pbulb size was
dramatic. Many are 1/3 to 1/2 again as large. The better light
just produces better growth.

Thanks, I guess I'll have to step up the fertilizer. I grow in S/H and
didn't have a shadecloth on the greenhouse last year because we had so very
much rain and if not rain then clouds, but when the sun came through it was
intense.
This year I have a 30% shadecloth on the house, because I noticed Phal
leaves being smaller (what Rebecca Northen calls - growing harder)
