Hello Permies!
I recently became involved with a project that has the lofty goal of growing citrus fruit in an underground greenhouse in the interior of BC.
We are considering several sites for the placement of the green house and the issue of winter sun has come up.
There is concern that inadequate sun during the winter will hinder growth, but by my estimation, the growth cycle of the trees would not be affected as the winter sun is not strong
enough to support much growth. I am unfamiliar with the growth cycles of citrus... So long as the temperature of the greenhouse can be maintained, is the amount of winter sun going
to play a major role in growth? Any advice or shared experience would be greatly appreciated! Thanks!
