That may be true, but for me, and this is just my experience and with my growing conditions, when I put my phals. outside, they seem to grow twice as fast, with no lag-time. Understand, phal. is not my main plant family, so others have much more experience in them than I. My greenhouses have all kinds of air movement (my orchid greenhouse has four fans running from 8:00 AM until 7:00 PM) but for some reason, when my plants go outside, they just grow better. Perhaps it is the humidity, and a lot is given off by my oak trees, perhaps it is and lack of intense heat, my greenhouse does get hot, and perhaps it is simply the natural, dappled shade with some early morning or late afternoon sun. What ever it is, my orchids, and the other tropical plants I grow, seem to flourish being outside.
