So. I decided to email Dr. Patricia A. Rorabaugh who has a Master's degree in Plant Physiology. I asked if ebb was any better than dwc. and the differences between them.
The reply i got was:
Both flood & drain and deep water culture are good methods of hydroponics. I've never heard that one is favored over the other. Both provide water and nutrients to the roots. Oxygen is provided in flood and drain systems every time the water drains. In deep water culture systems one would have to add oxygen via bubblers.
Certainly the choice of plants to grow may be a factor in any results found from a comparison. If you grow large tomato plants, flood & drain many times a day for good aeration but do not use bubblers for aeration in the deep culture system, then yes the flood & drain plants will probably do better. So, make sure your are giving your plants the same conditions (water, nutrients, oxygen and aerial environment). The only difference should be the systems used. Good luck with your project.
Dr. Rorabaugh
I shall be happy to forward the Email to anyone who would want it. she also seems very helpfull if you tell her its for a school project. Hehe.
This is her info page hXXp://ag.arizona.edu/PLS/faculty/rorabaugh.html
