they need the fan before going outdoors so get them used to it by diverting the wind...iow, give the wind an indirect shot to the plants then gradually move the wind into them, a little every couple days (same for the sun when moved outdoors). otherwise you'll most likely bury them deep to make up for the scrawny-ness which'll bring up a new set of probs (damp off mainly). it's still a bit early for outdoors so you have a couple weeks at least to get em strengthened up...i wait until the end of may.
