ok been going for about 2 weeks or so now and plant has roots (about 4) hanging down to the water and roots look great, growth however is slower than a turtle that was hit by a semi-truck!! Was running a pair of 75w cfl's over top of plant and just upgraded those to a pair of 100w cfl's. Could it be low light levels being the cause of slow growth? Comparing to the plants under the 400w MH which were started about 2 days earlier, the cfl plant is about half the size.
