What kind of nutrients are you planning to add to the water for the bulbs to get enough energy for ther growth? Are you looking into any specific nutrients for the tulip bulbs? Since hydroponics requires runnoing water and you are not able to provide such a condition, try to agitate the water in the different cups manually several times a day. In case your tulips are taking long to sprout, consider taking grown plants and estimate their growth in the different rooting mediums. Good luck!
