Many peolpe have asked, "why not hydroponics poinsettias"?
Hydroponic poinsettias simply aren't practical for to reasons:
1. Poinsettias are grown as a Christmas holiday plant and their bright, cheerful colors brightens any room. Unfortunately, after those colors begin to fade in 6-8 weeks it's time to send them to compost.
Because of their short life span, the advantages of hydroponic growing simply don't apply to these plants.
2. The market for poinsettias is extremely price sensitive. Commercial growers are forced to use the cheapest materials they can find to grow their crop. The cost of hydroponic supplies aren't the cheapest way to grow, so poinsettias and hydroponics don't work.
