I'm with both Mehitabel & Katrina - a good number of mine head outdoors as soon as weather permits - usually about mid April to late April and then stay out until Late September to mid October depending upon the year. They love it outside and I've never had bug problems from the move. As noted the AMOUNT of light you give them outside can be difficult to determine, especially the transition phase as there is MUCH more light outside than indoors under artificials. Nearly any orchid could potentially be grown indoors under lights if you are willing to invest in the hardware to give them the entensity and temperature/humidity that they want. I suggest you tell us what YOU would like to grow indoors and move outside in the summer and we'll give it our best shot telling you what you will need to do to make that happen. Sound good?
