I wanna give you my 2 cents, make sure there are enough air bubbles supply to all the plant site and dont forget your get root balls. If there are more bubbles/air on one side then that side would grow alot more then the other side and will overshadow the side with least bubbles. That is what i learn from my first dwc/sog grow.
And another consideration is plant support, if you plan on vegging for a few days then pruning(which u should or else you'll end up with a huge bush and alot of non-compact buds) don't forget about plant support trillis nettings works great.
