if they were mine, i would find a bucket large enough to fit them into and put the plant pot in the bucket then add water to about half way up. being carefull that the medium isnt starting to float on the top f the warter level and give them a good soaking. then once all the medium is wet, go from there with the watering, the roots will be cruing out for someware to get food and it promotes a better root system and avoids dry spots/pockets in the medium. dont be afraid to get the mredium wet in the begining, nothing worse then roots trying to grow in to dry soil and dying
