Hello GarlicToast , can I just ask how many plants are we talking about ?..............
A 1000 watt HPS should be adquate for flowering a fair number of plants.

Anyway, if you wish to add a bit of MH into the mix it definately isn't going to hurt anything but as for increasing potency, I really couldn't imagaine that happening. I think the only way of ensuring good potency is to get hold of the best possible seeds to begin with
