Actually, I think that Home Depots (and the like) do it to their plants so that in late winter ~ early spring the flowers are all blooming in their stores, until you get them home and put them into the soil where they lose their flowers until later. JMO of course.

Had a temperature issue with that HD light in my fuge, shot way up to 84.7 degrees. Put a fan in their set on low turned off the HD light and the water temp dropped to 77.5 degrees. Turned the HD light back on and left the fan on one... got to find that happy medium...
