Ive started in soil and gone to hydro, meaning the roots grow out of a paint strainer filler with soil into the air and down into an aerated nutrient solution, and current have 3 gal soil pots with the bottoms cut out and placed in a bubbel bucket top then place in a bucket, so i only have to keep the bucket filled and not water the soil, because marijuana feeds from the tips of the roots. Anyway, to answer your question, you could, it might shock them a bit, and be kind of backwards but you could do it.
Have fun
