Building a "small scale personal grow room" for a friend. With practically unlimited space, i am trying to setup a 2 stage system. A vegetative room for motherplants and cuttlings. And a flowering stage for matured cuttlings (allowing more harvests).

I want to use a 400 Watt HPS for the flowering and a MH light of some kind for vegetative.

1. How many plants should i flower at one time?
2. How many Mothers do i need?
3. How many watts for the MH light?
4. How big should each room be?
5. Expected yield?

Please share comments or suggestions.
