Switching from Megagarden to Waterfarm

I just made the switch last night from the Megagarden to the Waterfarm with 4 modules and the 15 ga. res. I made the switch b/c I was tired of having the plants roots just sit there and not thrive like they can in a 2 gallon container along with the vesatlity of being able to move the plants around. I have the 4x4 huydrohut, 600 watt hps, Co2, portable a/c using GH.

Has anyone used the Megagarden then switched to the Waterfarm or vice-versa? If so, please comment.

Thanks.
