| Just as a postscipt - since adding these posts a few years ago, I invested in a white plastic 'greenhouse' to house my growing collection. The orchids in it have now been through 9 mths of growth, and are starting to flower. The results have been amazing - and I now have no concern about the colour... the flowering rate is way superior to the shadecloth house i'd tried before (due largely to some limited insulation at night and 'greenhouse' effect during even the coldest winters' day). |
