|I am trying to raise water hyasis (spellling)over the winter in my basement due to the high costs of them at our local nursey in the spring, plus the fact that it takes them awhile to spread. They have not spread very well this past summer due to the fish eating the roots all the time. I built a large holding tank and have placed some plants in it from the water garden this fall. They are not spreading very well, even though I have a grow light on them. I was wondering if having the light "on" 24 hrs. a day harms them? They have spread a little, but some of the leaves are turning brown, (the ones that appear to be under water). Any suggestions to get them to reproduce? I have an arreator from a acquarium in the tank also.
