i would not suggest a DWC for moms because it needs to be maintained at the right temps in all seasons since moms are grown all through the year.you will also be changing airstones and pump. i would suggest growrocks with drip system or hempy buckets, or flood/drain, thats much less temperature sensitive. add to it that moms dont need to be grown at maximum rate, because lighting is not max so a simple handwatering hempy buckets would be simplest. thats how i kept them for years under fluro tubes shoplights and they gave me much more clones than really needed
