You have net pots. I would go with the drip and recirculate. Drop the pump into the rez. I'm not too familar with ebb and flow but drip can run 24/7 without problems. As soon as that sprout comes up good 3 or 4 sets of leaves fill with rocks.
Indoor grows are mostly indica to keep the hieght down but alot are mixed. Indica's can be really stoney.
Yea it's good to learn from the bag seed. Besides most all strain are chronic, it's all in the grow. They will suprize you as to how good they can be. Most bagseed are sativa because they are grown outside to be very tall.

Plant a few of you new seeds and proof them under fluro's then back to veg and you have mothers to clone from . This way you save seeds and time on having males. Cloning is easy.
