i would think dwc would be best it's alot less to deal with i think either the bucket system or 30 gal res type like i have i have a areo/dwc i combined them both i took a 30 gal rubbermaid tub and then took sum 1/2 inch pvc with 4 elbows and cut to fit where it was a lil bit bigger than the res so when u fit it in it's a tight fit drilled holes for my sprayers 4 for the sides and 3 each on the front and back and on 1 of the elbows i bought 1 elbow with a 1/2 inchhole in the bottom so i could screw in the 1/2 adaptor so i could hook it to my pump then just put the pump in the res hook it to the elbow with the adaptor and ur good to go. and as far as draining goes i have a water pump i drop into the res with a hose that is hookup to a pvc drain i installed in the wall that goes outside i ran it about a ft under the ground with sum pea rock so it will drain good and sum i pump into a bucket to water my plants with.and the dwc part is i have 2 dual airhog stones i drop in the res and when i see the roots gettin thick i pull them out and let the roots get a lil thicker then i drop the stones back in where there not tangled with the roots. i have 6 fems now and close to 40 tops at 4 ft tall and 5 that tops that are 5 ft tall i have to bend them the growth is nothin less than amazing.im using advance nutes 3 part and there really good i think + i added calmag+,enngy's f1,silca boost,liquid carbo load,dr hornsby big blood,budblood,and koolbloom along with a 1/4 tsp of epson salt and proxide oh yea and sum hygrozime that stuff is great.i have yet to have any problems other than me messing up and adding to much ph down when i was changing out my nutes 1 time the will wilt droop quick i was adding 10 to 15 ml per res every change and that time i did'nt change out i just topped off the res and for sum reason i was'nt thinking and added the phdown but i fixed it quick lol.
