Your not wrong. I'm not sure if he has a driver for it or just the board. What i was saying is sometimes you end up paying more for less when trying to incorporate something you already have and it may be beneficial to look at other options not just focus on using it. There are many ways he could go. I'm just trying to provide some prospectives so he can make an informed decision.
I kinda feel like limiting himself to incorporating it is not the option i would choose but its not my decision. I think that 1 QB would prob serve just as well for clones/seedlings from a bang for buck prospective.
