Transporting plants from one place to another is not very smart. How are you going to move 2 foot plus plants around without being noticed. People have been busted trying to do this. If you use flouros for veg, that would be a huge help, flouros use next to no power at all. Plants don't need nearly as much light during veg as they to in flower, so you don't need a HID system for that. Keeping them in the same place is a lot more convieneint and safe.
