I will be installing a growing cart with the tent cover shortly to put my orchids and other tropicalÂs in for the winter. (Follow link for info on the cart). Each tray will have a plastic grate in it to keep the pots out of any drainage water. The light fixtures (3 of them) will be four bulb 48" Fluorescent Grow Fixtures. I am not sure if they come with or with out the bulbs. If I need to purchase bulbs what are the recommendations from the group?

My questions are:

I have researched a lot of sites on the internet and books and I find that most of info I have reviewed state that using a mixture of Cool white and Daylight bulbs is just as good or better than using Plant Bulbs. What is the consensus of the forum on this?


Since the Tent/Plastic cover will be part of the over all growing structure to help maintain humidity levels should I also install some low voltage (12VDC) muffin fans for air circulation?

If there are any other comments please feel free to post them.

Thanks
