Yes DWC will greatly increase the yeild production and shorten ur time a little not much though and about ur space umm i have a 5x8 room with 60 plants under 1 1000w hps so ya i think you will be fine with wall to wall plants if you wanted and about the multi system u can go to walmart or a 99c mart and pick up those plastic storage bins and pick urself up some net pots or make ur own and cut holes in the top of the bins and set ur net pot in it i would suggest u get some black spraypaint if you use the bins and paint the whole outside so no like shines through but you dont want the plants to close the get huge yep something like this!!!! but to be honest with you i personaly like the buckets so i can control them one by one!!!! but good luck!!!!!:thumbsup::thumbsup::rastasmoke:
