I have run Organic Soil, DWC, and Ebb and Gro all at the same time this past gro.. ALL plants were the same strain... an elite clone only strain that I have.... My Organic soil produced the least budd... each plant only gave up about 3 ounces, while the Ebb and Gro avged 12 ounces each... the One DWC that I did... produced 19.5 ounces. I just started 4 more clones and am building single unit DWCs for them. The reason for the varied growing methods was because I made too many clones and was planning on culling any that were slow to take root... but that didnt happen - they all established nice roots and were reaching for the sky in my aerocloner... so since I had extra I decided to try soil out... And Since I got the DWC as a gift I figured I would throw one in it just to see... wow is all i can say. I found the the Self Contained DWC easy to run and easier to maintain than the larger res...
Note: all budd is wet weight....
