Before attempting to force spring flowering bulbs for hydroponic growth, it is recommended to let the bulbs recover in soil, since they're depleted from having bloomed once. Please see here for our instructions for that.
When it comes to putting the bulbs back in the vase during the season, we cannot guarantee success. Our growers use a complicated process over the course of weeks to prepare the bulbs so they can thrive hydroponically. However, after having been in the soil for the right amount of time you can try to have them live out their second life-cycle in the vase for the duration of the blooming period. The bulbs are alive and sensitive to abrupt changes in their environment, switching them over to another is a delicate process.
At some point in the future we might put up a video of our own with our head grower explaining how. For now, have a look at some useful videos below. They were selected from YouTube by our grower.
