2 150w hps sog

I've done a few successful grows with autos and one single blue mistic plant, but this is my first time attempting a perpetual harvest...my vision right now is single colas (mother is a dinafem blue hash) 9 freshly rooted clones flowered in 2l bottles with no veg...9 under each light staggered 4 weeks...I'm thinking 12-20g per cola so anywhere from 4oz to 6oz every 8 weeks....does that seem doable to those of with single cola sog experience? Could I go even smaller? Maybe 1l bottles? I know the 150s don't have much penetration, so im thinking cramming a bunch of small single colas would be most effecient

It should work out perfectly, just be sure you aerate the water thoroughly to avoid root rot. Are you planning to do 12/12 directly after rooting? That would be best if you are doing it in 2 liter bottles.
